one
Construction Background In recent years, with the rapid progress of optical fiber in copper, optical fiber to the building, and optical fiber to the home, access network construction has ushered in the era of FTTx based optical fiber access. A large number of access optical cables converge to different computer rooms such as OLT, transmission, and data. The number of optical cable terminals in the computer room continues to increase, and the number of optical fiber hops is also increasing, The demand for optical hop management and flexible scheduling has also been further improved, but due to the limitations of the traditional ODF frame's own hop management capability and scalability, the following problems are mainly caused:
one point one
Chaotic management The existing incoming optical cables are distributed in various professional computer rooms, and all are equipped with ODF optical distribution frames. Most businesses require more than two professional computer rooms to achieve fiber hopping. The amount of optical cables between computer rooms is large, and the routing and fiber hopping are chaotic, which makes it impossible to achieve unified management and is not convenient for adjustment and maintenance.
one point two
The traditional "small and complete" layout structure of ODF shelf with unclear boundaries blurs the interface of construction and maintenance, which is easy to become the repeated winding of jumping fibers, which is not conducive to flexible scheduling and is not suitable for the construction of larger capacity.
one point three
The access layer optical cable and the trunk layer optical cable are terminated in the same ODF frame, and the frequent construction and maintenance of the access layer optical cable can not guarantee the safety of the trunk layer optical cable, so there are hidden dangers. With the further promotion of the access network optical fiber strategy, the above problems will become increasingly serious. For this reason, the installation of optical fiber distribution frame (MODF) should be considered in the planning and construction of the computer room in the future to gather a large number of access optical cables, and gradually solve the maintenance, management, security and other problems.

I. Construction Background
In recent years, with the rapid progress of optical fiber into copper and back, optical fiber to the building, and optical fiber to the home, the access network construction has ushered in the era of FTTx based optical fiber access. A large number of access optical cables converge to different computer rooms such as OLT, transmission, and data. The number of optical cable terminals in the computer room is increasing, and the number of optical fiber hops is also increasing, The demand for optical hop management and flexible scheduling has also been further improved, but due to the limitations of the traditional ODF frame's own hop management capability and scalability, the following problems are mainly caused:
1. Management confusion
The existing incoming optical cables are distributed in various professional computer rooms, and all are equipped with ODF optical distribution frames. Most businesses require more than two professional computer rooms to achieve fiber hopping. The amount of optical cables between computer rooms is large, and the routing and fiber hopping are chaotic, which cannot achieve unified management and is not convenient for scheduling and maintenance.
2. The boundary is not clear
The traditional "small and complete" layout structure of ODF frame blurs the interface of construction and maintenance, which is easy to cause repeated winding of fiber hopping, which is not conducive to flexible scheduling and is not suitable for construction of larger capacity.
3. Unclear hierarchy
The access layer optical cable and the trunk layer optical cable are terminated in the same ODF frame. The frequent construction and maintenance of the access layer optical cable cannot guarantee the safety of the trunk layer optical cable, and there are hidden dangers.
With the further promotion of the optical fiber strategy of access network, the above problems will become increasingly serious. For this reason, the installation of optical fiber distribution frame (OMDF) should be considered in the planning and construction of the computer room in the future to gather a large number of access optical cables and gradually solve the problems of maintenance, management and security.
2、 Introduction to MODF and establishment of relevant standards
Optical Fiber Main Distribution f rame， Referred to as MODF, hereinafter referred to as OMDF) applies all the use and maintenance methods of MDF, with in-line and horizontal end modules. The in-line side is connected to the external optical cable, and the horizontal side is connected to the optical communication equipment. The communication route can be distributed and connected through the fiber hopping. It has horizontal, vertical, front and back fiber paths, which is convenient for the maintenance, management and expansion of high-capacity fiber hopping, and can be installed with link test ports.
At present, there are no national and industrial standards for OMDF, mainly referring to YD/T 778-2006 Optical Distribution Frame, Q/CT 2354-2011 Technical Requirements for China Telecom Optical Distribution Frame, and the enterprise standards of domestic and foreign optical distribution frame manufacturers.
3、 Applicable scope of OMDF
OMDF is applicable to the access layer central office (OLT office) and similar central machine rooms, for the centralized termination, connection scheduling, monitoring and measurement of access equipment optical cables and external MAN backbone optical cables. It is also applicable to large and medium-sized transmission machine rooms, but the access layer MODF and trunk layer MODF should be set respectively. OMDF
4、 OMDF Classification and Structure
The OMDF is mainly divided into two categories: integrated fusion and separation fusion (frame height is 2600mm, 2200mm and 2000mm).
1. Melting and matching integrated OMDF melting and matching integrated MODF: It consists of the distribution frame on the line side connecting the external optical cable and the line side connecting the optical communication equipment. The in-line side and the horizontal side can be integrated racks or separate racks.
The rack is mainly composed of the rack top base, base, framework, door (when required), optical cable fixing stripping unit, grounding, in-line module, jump fiber receiving unit, horizontal module, horizontal wiring channel and accessories.
The following are introduced separately according to the integrated rack and the separated rack:
2. Integrated rack
The in-line rack and horizontal rack of the integrated rack are back-to-back structure, double side operation, and the parallel rack structure is relatively fixed and single. The in-line rack is composed of several end plates to form a unit, which uses 12 core fusion integrated tray components. The horizontal rack can adopt 12 core fusion integrated tray or 72 core fiber hopping frame components.
2. Split rack
The separated rack is composed of the optical fiber melt fiber terminal frame and the equipment side distribution frame, which are two separate optical fiber distribution frames. The combination is flexible, and can realize full front parallel frame structure or back-to-back parallel frame structure. The in-line rack is composed of several end panels to form a unit, which uses 12 core fusion integrated tray components. The horizontal rack can use 72 core fiber hopping frame or 12 core fusion integrated tray components. Two side parallel rack scheme of separate rack (combination of two front and back to back parallel racks),
3. The combination of fiber optic MDF of separate rack is flexible, and in practical application, multiple full front or back-to-back fiber hopping fields can be formed according to the capacity of the machine room.
4. Fusion separation type
Melting and separating OMDF: It is composed of fiber melting frame and fiber distribution frame, which are used together.
Fused fiber rack is a rack that leads all optical cables into the ground and concentrates the connection function with pigtail in the same subrack. The rack is composed of fixing, stripping, bundling, grounding, etc. of optical cables, and the two sides are the welding area of the welding plate.
Melting and separating OMDF fiber rack
The fiber distribution rack is a rack that centralizes all end forming functions in the same subrack and realizes the optical transmission routing and scheduling function. The rack is composed of an external line end forming area, an internal line end forming area, a tail cable fixing area, and a fiber hopping area. Each area is independent of each other. The external line and the internal line adopt the reversible fiber hopping unit frame. The combination scheme of fusion and separation OMDF is mainly based on single side operation,
The above is the combination and combination scheme of OMDF produced by mainstream manufacturers at present. The division of labor between the external line side and the equipment side interface of the double-sided rack is relatively clear, but double-sided operation is required; The full front frame can be installed back-to-back or against the wall, which is easy to operate. In engineering applications, appropriate rack and parallel rack schemes can be selected according to the specific application scenarios, management modes, operation habits, and capacity requirements on the outside line side and equipment side to build a high-capacity fiber hop field with good capacity expansion, clear fiber hop management, and flexible use.
5、 OMDF application
OMDF installation scenario
OMDF should be installed as close to OLT or Other equipment Machine room, and consider outgoing The Conduit The routing, capacity and other factors of physical channels such as shafts and channels in the building can be divided into settings on the same floor (or in the same machine room) and settings on different floors. The specific settings can be selected according to the following priority:
1. When the space conditions of the existing cable distribution room are met, the cable measurement room is preferred to set OMDF;
2. When the space conditions of the existing cable distribution room are not satisfied, the OMDF equipment should be in the same machine room as the OLT equipment as far as possible;
3. If the existing OLT or transmission room space conditions are not met, separate OMDF rooms can be set on the same floor or different floors.
6、 Requirements of OMDF installation on computer room
The OMDF machine room should try to choose a machine room with sufficient length to make the OMDF be placed in a row as far as possible to form a fiber hop field. If it is placed in two columns, the fiber jumpers between columns can only go through the cable rack on the top of the machine room, which is not conducive to maintenance.
When OMDF and other equipment are set in the same machine room, the area of the machine room should be based on the final capacity of the machine room, and the demand space and reserved space for OMDF, OLT, dedicated line access equipment, power supply and other equipment should be comprehensively considered; When setting different machine rooms, only the space required by OMDF and the reserved space need to be considered, and at the same time, the installation position reservation of online test equipment should be considered. OMDF
1. Suggestions on connection between OMDF and equipment
When connecting OMDF and equipment, it is recommended to select the tail cable. According to different use scenarios, dual head or single head (welded on the OMDF equipment side) pigtail can be selected
Note: When the cable is set in the same machine room or on the same floor, the length of the tail cable between the OMDF and the equipment is well controlled, and it is recommended to use double end tail fiber connection or tail fiber connection; When different layers are set, it is difficult to measure the tail cable length between the OMDF and the equipment. The OMDF head and tail cable or the indoor optical cable with single head and tail fiber customized by the manufacturer shall be used for connection. The 12 core fusion integrated tray shall be selected at the equipment side of the OMDF rack. OMDF
7、 Conclusion
With the promotion and use of OMDF, it will gradually solve the problems of chaotic management, difficult expansion, and difficult maintenance of optical cables in the current agricultural production system room. However, the introduction of each new product requires a certain running in period, which urges us to continue to study in depth how to combine the evolution with the existing network and long-term deployment scheme to meet a large number of business needs of future users.

What is optical fiber communication
Optical fiber communication is a kind of communication means which uses light wave as carrier and optical fiber as transmission medium to transmit signals from one place to another.
Advantages of optical cable communication
Compared with the previous electrical communication, optical fiber communication has many advantages: its transmission frequency bandwidth and communication capacity are large; Low transmission loss and long relay distance; Fine wire diameter, light weight, raw material is quartz, which saves metal materials and is conducive to rational use of resources; Strong insulation and anti electromagnetic interference performance; It also has the advantages of strong corrosion resistance, strong radiation resistance, good flexibility, no electric spark, small leakage, strong confidentiality, and can be used in special environments.
3 Application and development of optical fiber communication in power system
The power system communication network is a large-scale and well-developed special communication network specially used in China. With the acceleration of the trend of optical fiber communication network, the process of transition from trunk line to access network to optical fiber has been basically completed in many areas of China's power special use communication network. At present, the services carried by the power system optical fiber communication mainly include voice, data, broadband services, IP and other conventional telecommunications services; The professional business of electric power production includes protection, automatic safety devices and broadband data required by electricity marketization. In particular, the protection and safety automatic devices put forward higher requirements for the reliability and safety of optical cables. It can be said that optical fiber communication has become an indispensable part of the safe and stable operation of the power system and the production and life of the power system (public number: transmission and distribution lines).
At the beginning, the application of optical fiber communication in electric power communication was to lay ordinary optical fiber cables by the traditional buried, pipeline, overhead and other methods of the telecommunications department to form the electric power optical fiber communication system. With the progress of technology, in the 1970s and 1980s, some optoelectronic composite optical cables, which are different from traditional optical cables and are attached to power lines and power towers, were developed. These optical cables are collectively referred to as power special optical cables. One of the major differences between power system optical fiber communication and other optical fiber communication systems is the particularity of communication optical cables. The possibility of power special optical cable being damaged by external force is small, and its reliability is high. Although its cost is relatively high, its construction cost is low. After years of development, the manufacturing and engineering design of power special optical cables have become mature, especially the OPGW and ADSS technologies, which have begun to be widely used in domestic power special optical cables, such as the long-distance backbone OPGW optical cable lines in the Three Gorges Project. Relying on the power system's own line resources, special optical cables avoid conflicts and disputes with the outside world in terms of frequency resources, routing coordination, electromagnetic compatibility, etc., and have great initiative and flexibility.
The power system has a powerful power network, which is distributed in cities and rural areas all over the country. It is completely feasible to build an optical fiber communication network with the help of power lines and towers. It can also provide a broadband channel for the development of power grid automation and new relay protection. At present, the urban and rural power network transformation of the power system has also brought good opportunities for the development of power communication. Many provincial, prefecture (city) and county power bureaus have built optical fiber lines to make full preparations for the realization of broadband integrated services digital network (B-ISDN).
