Simplex LC 1.25Gb/S SFP Single Mode Fiber Module 20KM 1550/1310nm BIDI DDM
PRODUCT DESCRIPTION
1.25Gbps SFP BIDI Optical Transceiver Module Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA), The transceiver consists of four sections: the LD driver, the limiting amplifier, the 1550nm DFB laser and the PIN photo-detector. The module data link up to 20KM in 9/125um single mode fiber.
The SFP Module compliants with SFF-8431, SFF-8432 Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472. The fully SFP compliant form factor provides hot pluggability, easy optical port upgrades and low EMI emission.
1.25Gbps SFP BIDI 20KM Optical Transceiver Module is small form factor pluggable module for bi-directional serial optical data communications such as STM-8, OC-24,Fiber Channel, It is SFP 20-pin connector to allow hot plug capability. This module is designed for single mode fiber and operates at a nominal wavelength of 1550nm.
