1U Rack-Mountable 8-Channel SD/HD/3G-SDI over Single Fiber CWDM Uncompressed Extender
Model: LNK-SDI-8V Series
Overview
The LNK-SDI-8V Series is a professional-grade 1U Rack-Mountable
8-Channel SD/HD/3G-SDI
over Single Fiber CWDM Uncompressed Extender, specifically
engineered to meet the high-density,
long-distance transmission needs of broadcast, surveillance, and
industrial video systems. As a 1U
Rack-Mountable 8-Channel SD/HD/3G-SDI over Single Fiber CWDM
Uncompressed Extender, it
adopts a space-efficient 1U rack design—ideal for data centers,
broadcast studios, and control rooms
where rack space is valuable, while leveraging Coarse Wavelength
Division Multiplexing (CWDM)
technology to optimize single-fiber bandwidth utilization.
This extender supports uncompressed transmission of 8-channel
SD/HD/3G-SDI standard high-
definition video signals via a single fiber optical cable, ensuring
no loss of video quality during transmission
—critical for applications requiring broadcast-grade visuals. It is
equipped with a local SD/HD/3G-SDI
loop output interface, allowing on-site monitoring of video signals
to facilitate real-time troubleshooting
and ensure signal integrity before long-distance transmission. The
system consists of a dedicated
transmitter and receiver pair, specifically optimized for 1080P
3G-SDI signal transmission, with
backward compatibility for SD-SDI and HD-SDI formats to adapt to
diverse legacy and modern video
devices.
Beyond video transmission, the 1U Rack-Mountable 8-Channel
SD/HD/3G-SDI over Single Fiber
CWDM Uncompressed Extender integrates multi-signal synchronization
capabilities: it can simultaneously
transmit 8-channel SD/HD/3G-SDI video and 1-channel reverse RS-485
data over a single optical fiber.
The reverse RS-485 data channel supports reliable bidirectional
communication, enabling remote control
of PTZ cameras, video matrixes, or other RS-485-enabled
devices—enhancing operational flexibility in
large-scale video surveillance or broadcast networks.
In terms of performance, the extender delivers video quality that
meets strict broadcast industry standards,
with color accuracy, signal stability, and frame rate consistency
suitable for live broadcasting, post-production,
and high-end surveillance. Its audio quality reaches CD-level
clarity, ensuring synchronized, high-fidelity audio
transmission alongside video signals. The CWDM technology further
enables efficient use of fiber resources,
reducing the need for multiple fiber cables and lowering overall
infrastructure costs. With its robust multi-signal
support, rack-mountable design, and broadcast-grade performance,
this extender is an ideal solution for broadcast
stations, large-scale security surveillance systems, stadium video
networks, and industrial video monitoring
platforms requiring high-density, long-distance uncompressed SDI
transmission.
