HD-SDI extender
Preliminary Datasheet
General Description
HG-SDI extender increases transmission length of HG-SDI
signaling using single optical cable. Electrical-to-optical
and optical-to-electrical conversion technology enables
transmission length extending without any bulky cable
and repeater. Transmission length is up to 2km for HG-SDI.
It uses 5V power supply.
Features
 Reliable 850nm VCSEL and GaAs PIN PD
technology.
 Up to 3Gbps data link.
 Transmission length: up to 2km using 50m
OM3 multimode fiber at 1.485Gbps HD-SDI
 5V power supply.
 Supports video pathological pattern
transmission.
 Supported data rate: HD-SDI(1.485Gbps)
and SD-SDI(270Mbps) transmission is also
available by option.
 BNC connector for electrical in-out.
 ST connector for optical in-out.
 Mini USB for power supply.
Applications
 Broadcast video applications
 Digital Video Records (DVR)
 Surveillance / CCTV cameras
 Digital video displays
