1U Rack-Mountable 8-Channel SD/HD/3G-SDI over Single Fiber CWDM Uncompressed Extender
8-channel SD/HD/3G-SDI Fiber Extender Overview
The LNK-SDI-8V Series constitutes a professional 8-channel SD/HD/3G-SDI video
fibre transmission system that facilitates the delivery of broadcast-quality video
over a solitary optical fibre. This comprehensive solution comprises one transmitter
and one receiver, with the capacity to support 1080p 3G-SDI signals, accompanied
by CD-quality embedded audio and bi-directional RS-485 data transmission.
8-channel SD/HD/3G-SDI Fiber Extender Key features include:
►-channel video + 1-channel RS-485 data over single fiber
►Supports SD/HD/3G-SDI standards (up to 3Gbps per channel)
►Local monitoring via SDI loop output
►20km transmission distance (with single-mode fiber)
►Broadcast-grade video quality with zero latencyRack-mountable 1U chassis for professional installations
Ideal for broadcast studios, live event production, sports venues, and surveillance systems
requiring high-density, long-distance SDI video transmission.
