HD-SDI CWDM SFP Optical Transceiver 1270–1610nm 40km SMF DDM
Overview
The LNK-CWDM-SFP1G-XX40 is a broadcast-grade HD-SDI CWDM optical transceiver built for
long-haul video transport up to 40km over single-mode fiber. Supporting data rates up to 1.485Gbps
and all 18 CWDM wavelengths (1270–1610nm), it delivers robust performance under SDI pathological
patterns. With hot-swappable SFP form factor, integrated digital diagnostics, and low power consumption,
it is ideal for professional broadcast links, camera systems, and video routing networks.
Features
Transmits HD-SDI up to 1.485Gbps over SMF
Supports long-distance video extension up to 40km
Fully compliant with SMPTE 259M, 292M, 344M standards
Handles SD/HD-SDI pathological test patterns reliably
Available in 18 CWDM wavelengths (1270–1610nm)
Compact hot-pluggable SFP design with LC duplex interface
Built-in Digital Diagnostic Monitoring via I²C
Low power operation with wide 0°C ~ +70°C range
