HD-SDI CWDM SFP Optical Transceiver 1270-1610nm 20km MSA Compliant

Product Specification

Model: LNK-CWDM-SFP1G-XX20

 Product Description & Overview

The HD-SDI CWDM 1270~1610nm 20km Digital Video SFP Optical Transceiver (MSA) delivers reliable,

high-density video transmission for professional broadcast and surveillance applications. This MSA-compliant

optical transceiver supports the complete 18-wavelength CWDM spectrum from 1270nm to 1610nm, enabling

efficient utilization of existing single-mode fiber infrastructure. Engineered for stable operation across data rates

from 50Mbps to 1.485Gbps, the module ensures robust signal integrity when processing SDI pathological patterns,

guaranteeing consistent performance for SMPTE 259M, SMPTE 344M, and SMPTE 292M compliant video signals.

Designed for flexible deployment, this digital video SFP transceiver achieves transmission distances up to 20

kilometers while maintaining 1.5Gbps signal quality, making it ideal for metropolitan and campus-wide video

networks. The hot-pluggable SFP form factor ensures straightforward integration with a wide range of broadcast

equipment, including video routers, extenders, and media converters. Advanced DFB transmitter technology

provides precise wavelength stability, while built-in digital diagnostics via the I2C interface allow for real-time

performance monitoring and system management.

Certified for safe operation, this optical transceiver meets relevant industry standards for deployment in

professional environments. The CWDM wavelength division capability enables significant bandwidth expansion

without the need for additional fiber installation, offering a cost-effective solution for broadcasters, system

integrators, and network operators. This transceiver is particularly well-suited for high-definition surveillance

systems, multi-channel broadcast distribution, distance learning networks, and event production setups where

reliable, high-quality video transmission over intermediate distances is required.
