HD-SDI CWDM SFP Transceiver 18-Wavelength 20km MSA Compliant Digital Diagnostic

HD-SDI CWDM SFP Transceiver 18-Wavelength 20km MSA

Compliant Digital Diagnostic

Overview

The E-link LNK-CWDM-SFP1G-XX20 represents a high-performance, cost-optimized fiber optic solution specifically engineered for long-distance HD-SDI video transmission systems. This advanced CWDM SFP transceiver module delivers exceptional signal integrity across data rates ranging from 50Mbps to 1.485Gbps, maintaining reliable performance even when processing demanding SDI pathological patterns.

Compliant with Multi-Source Agreement (MSA) standards, this transceiver ensures broad compatibility with various host equipment while supporting comprehensive SMPTE 259M, 344M, and 292M serial interface standards. The module achieves extended transmission distances up to 20km over single-mode fiber infrastructure, making it ideal for connecting distributed video systems across campus environments and metropolitan areas.

Featuring complete wavelength coverage across all 18 CWDM channels from 1270nm to 1610nm, this innovative solution enables significant bandwidth expansion of existing optical networks without requiring additional fiber deployment. This wavelength flexibility allows system integrators and broadcast engineers to maximize their fiber infrastructure investment through efficient wavelength division multiplexing technology.

The transceiver's sophisticated design incorporates quality optical components that guarantee stable performance in demanding professional video applications. Particularly suitable for broadcast facilities, security surveillance networks, and distance learning systems, this HD-SDI solution provides broadcast-grade signal quality and transmission reliability where signal integrity and cost-effectiveness are equally important considerations.
