3G-SDI CWDM SFP Optical Transceiver 1270-1610nm 40km Digital Video MSA
Model: LNK-CWDM-SFP3G-XX40
Product Description & Overview
The 3G-SDI CWDM 1270~1610nm 40km Digital Video SFP Optical Transceiver represents a high-
performance fiber optic solution designed for bandwidth-efficient video transmission systems. This
MSA-compliant transceiver module supports comprehensive 3G-SDI signal transmission across all
18 CWDM wavelengths from 1270nm to 1610nm, enabling significant expansion of existing fiber
infrastructure capacity without requiring additional fiber strands. The module maintains robust
performance with data rates ranging from 50Mbps to 2.97Gbps, ensuring reliable operation even
when processing challenging SDI pathological patterns.
Engineered to meet stringent industry standards, this optical transceiver delivers exceptional signal
integrity for SMPTE 259M, SMPTE 344M, SMPTE 292M, and SMPTE 424M serial interfaces while
achieving maximum transmission distances of 40 kilometers over single-mode fiber. The compact
SFP form factor provides flexible deployment options in various video transmission equipment,
including SDI extenders, video routers, and media converters. The module's sophisticated laser
technology ensures consistent performance across the entire CWDM spectrum, making it ideal
for dense wavelength division multiplexing applications in broadcast and professional video
environments.
Certified as Class I Laser products according to FDA/CDRH and IEC-60825 safety standards,
this transceiver guarantees safe operation in diverse installation scenarios. The advanced design
incorporates temperature-stabilized laser components that maintain precise wavelength accuracy
across varying environmental conditions. This reliability makes the module particularly suitable for
broadcast facilities, outside broadcast vehicles, sports venues, and surveillance systems requiring
high-density video transmission over extended distances. By leveraging CWDM technology, users
can effectively multiply their existing fiber capacity while maintaining the signal quality and reliability
essential for mission-critical video applications, establishing this transceiver as an optimal solution
for expanding video transmission capabilities in bandwidth-constrained environments.
