1.25Gb/S Single Mode Fiber Module BIDI 1550/1490nm Simplex LC SFP 60KM Distance
PRODUCT DESCRIPTION
This module is designed to be compliant with SFF-8472 SFP Multi-source Agreement (MSA)
The SFP transceivers are high performance, cost effective modules supporting 1.25Gbps/1.0625Gbps data-rate and 60km transmission distance with SMF.
1.25Gbps SFP BIDI 60KM 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.
The SFP provides an optical link budget of 24 dB, but the precise link span length depends on multiple factors such as fiber quality, number of splices, and connectors.
