TX1490nm RX1550nm 1.25Gbps Optical Transceiver Module SFP 60KM BIDI
Single-mode
PRODUCT DESCRIPTION
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 1490nm.
1.25Gbps SFP BIDI 60KM 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 DFP laser and the
PIN photo-detector .
The transmitter section uses a multiple quantum well laser and is a
class 1 laser compliant according to International Safety Standard
IEC-60825. The receiver section uses an integrated InGaAs detector
preamplifier (IDP) mounted in an optical header and a limiting
post-amplifier IC.
This module is designed to be compliant with SFF-8472 SFP
Multi-source Agreement (MSA)
