CWDM SFP 1.25Gbps 41dB LC Optical Transceiver Module

CWDM SFP 1.25Gbps 41dB LC Optical Transceiver Module

The EOLS-1612-C series single-mode transceiver is small form factor pluggable module for serial optical data communications such as Gigabit Ethernet 1000BASE-ZX and Fiber Channel 1x SM-LC-L FC-PI. It is with the SFP 20-pin connector to allow hot plug capability. This module is designed for single mode fiber and operates at a nominal CWDM wavelength. A guaranteed minimum optical link budget of 41dB is offered. The transmitter section uses a multiple quantum well CWDM DFB laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses an integrated InGaAs Avalanche photodetector preamplifier mounted in an optical header and a limiting post-amplifier IC.The EOLS-1612-CD series are designed to be compliant with SFF-8472 Multi-Source Agreement (MSA).
