HD-SDI CWDM Optical SFP Transceiver 1270–1610nm 20km SMF DDM
Overview
The LNK-CWDM-SFP1G-XX20 is a compact HD-SDI CWDM optical transceiver designed for
professional video transport over single-mode fiber up to 20km. Supporting 18 CWDM channels
across 1270–1610nm, it ensures stable 1.485Gbps signal transmission while handling pathological
SDI patterns with ease. Its hot-pluggable SFP design, integrated diagnostics, and low power profile
make it an ideal solution for broadcast, video routers, and high-density camera systems.
Features
Supports 50 Mbps to 1.485 Gbps transmission rates
Extends HD-SDI video over SMF up to 20km
Fully compliant with SMPTE 259M, 292M, 344M standards
Handles SD/HD-SDI pathological patterns for reliable broadcast
Available in 18 CWDM wavelengths (1270–1610nm)
Hot-pluggable SFP MSA design with LC duplex connector
Built-in Digital Diagnostic Monitoring via I²C
Operates from 0°C to +70°C with low power consumption
