3G-SDI CWDM 40km Optical Video SFP Transceiver 1270–1610nm MSA
Overview
The LNK-CWDM-SFP3G-XX40 is a high-performance CWDM optical SFP transceiver designed for
long-distance 3G-SDI/HD-SDI/SD-SDI video transport over single-mode fiber. Supporting data rates
from 50Mbps to 2.97Gbps, it ensures stable broadcast-grade video delivery up to 40km, even under
pathological SDI patterns. With 18 selectable CWDM wavelengths (1270–1610nm), this compact
hot-pluggable module enables broadcasters and video operators to expand bandwidth without laying
new fiber. Digital diagnostics (DDM/I²C) further improve system reliability and ease of monitoring.
Features
Supports SD-SDI, HD-SDI & 3G-SDI per SMPTE 259M/292M/344M/424M
18 CWDM wavelengths (1270–1610nm) for flexible deployment
Up to 40km reach over SMF at 3Gbps pathological signals
Hot-pluggable SFP form factor, MSA compliant
Digital diagnostics (DDM) via I²C interface
Robust against pathological test patterns, ensuring video integrity
Low power consumption, single +3.3V supply
Operating temperature: 0°C ~ +70°C
Compact design, lightweight (25g)
Broadcast-ready Class I laser device, FDA/IEC-60825 certified
