LC Connector 60KM 155Mbps Optical Transceiver Module BIDI TX1550nm
RX1490nm SFP
PRODUCT DESCRIPTION
155Mbps SFP BIDI 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.
155Mbps 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 five sections: the LD driver, the limiting
amplifier, the digital diagnostic monitor, the DFB laser and the
PIN photo-detector .The module data link up to 60KM in 9/125um
single mode fiber.
