In practical applications, there is no fixed choice, and you need to choose according to your actual use, mainly from the five aspects of connector, single-mode/multi-mode, single-fiber/dual-fiber, length and optical module connection. In this issue, ETU-LINK mainly analyzes the selection of optical fiber jumpers and the connection scheme of optical modules.
Optical fiber patch cords conform to the telcordia GR-326-CORE standard and have the characteristics of low insertion loss, good repeatability, high return loss, good inter-insertion performance, good temperature stability and strong tensile performance. Select the correct connector. If the interfaces at both ends of the device are the same, LC-LC, SC-SC, MPO-MPO can be used for connection. If the interfaces at both ends of the device are different, LC-SC, LC-ST, and LC-FC can be used. connection method. Single-mode is mainly used for long-distance transportation, and multi-mode is mainly used for short-distance transportation. The single-fiber jumper has only one line, which is connected by a bidirectional (BIDI) optical module, and the dual-fiber is two lines side by side, which is connected by a dual-fiber optical module. The length of the fiber jumper can be determined according to the distance between the equipment and the equipment.
Alphabet parsing:
SX : Simplex, single fiber DX: Duplex dual fiber
SM : Single Mode MM : Multimode
MPO, LC, SC, ST, FC indicate connector type
PC, UPC, APC indicate end-face contact method
MPO-MPO: MPO connectors on both ends
MPO-4xLC: MPO connector on one end and 4xLC connector on the other
LC/UPC-LC/UPC: Both ends are LC connectors, and the fiber end face is UPC
