Optical fiber distribution frame (ODF) is used for terminating and distributing the trunk optical cable in the optical fiber communication system.It can easily realize the connection, distribution and scheduling of optical fiber lines.
With the increasing degree of network integration, the optical number hybrid distribution frame with ODF, DDF and power distribution unit has appeared, which is suitable for small and medium-sized distribution systems from fiber to cell, fiber to building, remote module and wireless base station.

OM2, OM3,OM4 fibers belong to the A1a fiber specified by IEC 60793-20, A1a fiber adopts 50/125 structure, 50μm core and 125μm coating, OM2 is A1a.1, OM3 is A1a.2, OM3 is A1a.3,OM4 is A1A. OM3 and OM4 are laser-optimized fiber types that offer higher transmission bandwidth in the 850nm transmission window.
OM4 cable is an ISO/IEC 11801 approved building level and trunk cable type and is also used for data center level and trunk connections. The OM4 cable can support 10GBase-SR up to 400 meters, which is longer than the OM3 cable transmission, and some switches on the market can support up to 550 meters.
The OM4 cable can support 40G/100G transmission to 150 meters, which is 50% more than the 100 meters transmission distance of the OM3 cable, so it is considered to be more suitable as a multimode cable type to support 40G/100G transmission, using the 8-channel 100GBase-SR4 protocol, OM4 cable can support 100 meters.

Single-mode fiber has a core diameter of 10micron, allowing single-mode beam transmission, and reducing the limits of bandwidth and Modaldispersion, but because the core diameter of single-mode fiber is too small, it is difficult to control beam transmission, so it requires an extremely expensive laser as a light source. The main limitation of single-mode fiber optic cable is the material dispersion (Materialdispersion), single-mode fiber optic cable mainly uses laser to obtain high frequency width, and because LED will issue a large number of different bandwidth light sources, so the material dispersion requirement is very important.
Compared with multi-mode fiber, single-mode fiber can support a longer transmission distance of 100MBPS Ethernet or 1G gigabit network, and single-mode fiber can support a transmission distance of more than 5000m.

The refractive index distribution is similar to that of the mutant fiber, and the core diameter is only 8-10
μm, the light rays propagate in a straight shape along the central axis of the fiber core. Because this fiber can only transmit one mode (two polarization states degenerate), it is called single-mode fiber, and its signal distortion is very small.

OM3 multimode cable is a fiber optic cable made of OM3 multimode fiber plus indoor or outdoor sheathing, which is often used for building trunk laying and trunkconnectionbetweentwobuildings in close proximity.
OM1,OM2, OM3,OM4 fibers belong to the A1a fiber specified by IEC 60793-20, A1a fiber adopts 50/125 structure, 50μm core and 125μm coating, OM2 is A1a.1, OM3 is A1a.2, OM3 is A1a.3,OM4 is A1A. OM3 and OM4 are laser-optimized fiber types that offer higher transmission bandwidth in the 850nm transmission window.

The transceiver wavelength of the optical modules at both ends of the optical fiber jumper must be the same, that is, the optical modules at both ends of the optical fiber must be of the same wavelength, and the simple way to distinguish is to have the same color of the optical modules. In general, multi-mode optical fibers (orange optical fibers) are used in short-wave optical modules, and single-mode optical fibers (yellow optical fibers) are used in long-wave optical modules to ensure the accuracy of data transmission.
After the optical fiber jumper is used, the optical fiber connector must be protected with a protective cover. Dust and oil will damage the coupling of the optical fiber.
