1.25G Single Mode SFP Module - CWDM DFB Duplex LC 40KM With DDM
Product Description:
The LNK-CSFP-1Gxx-40 series single mode transceiver is a small form factor pluggable module for duplex optical data communications, such as Gigabit Ethernet (1000BASE-ZX) and Fiber Channel 1x SM-LC-L FC-PI. It comes with a SFP 20-pin connector to allow for hot-plug capability. This module is for single mode fiber and operates at a nominal CWDM wavelength, with eighteen center wavelengths ranging from 1270nm to 1610nm, each at a step of 20nm.
The transmitting section of this module features a multiple quantum well CWDM DFB laser, and is designed to be a class 1 laser compliant with he international safety standard IEC-60825. The receiver section is composed of an integrated InGaAs detector preamplifier (IDP) mounted in an optical header, as well as a limiting post-amplifier IC. Above all, this transceiver is designed to be compliant with SFF-8472.
Features:
This 18-wavelength CWDM DFB LD transmitter is engineered to meet SFP MSA and SFF-8472 standards, and is also fully compatible with SONET OC-24-LR-1. With 1.25Gbps data-rate and a single +3.3V power supply, it boasts a hot-pluggable SFP Footprint Duplex LC form factor.
The operating case temperature ranges between 0°C and +70°C with extended options at -20°C to +85°C and -40°C to +85°C for industrial applications. It offers 1270nm to 1610nm wavelength range and 20nm step.
