1 Product Overview
1.1 Introduction
SDI fiber transceiver adopts the advanced non-compression digital HD video and high-speed digital
optical fiber transmission technology which converts SDI digital signal to optical signal via
fiber-optical and it can transmit up to 20 km. It is used in public security, school, residence and office
environments.
1.2 Features
Digital non-compression encoding technology.
Auto recognition of video input format.
Support 1-ch SDI and RS485 control data transmission on single fiber.
RS485 speed support 115200bit/s and below.
Support DC12V power supply.
Support video format of 720p/25, 720p/30, 720p/50, 720p/60, 1080p/25, 1080p/30 and 1080i/60.
LED status indicator display fiber transceiver’s working status.

4 FAQ
Problem
Possible Cause
Solution
Video signal blanking
Fiber cable, video line
connection are abnormal.
Properly connect fiber cable, and
may judge according to device
indicator.
Video line is too long.
Use better cable, and make 75-5
line > 100m
Sending end and receiving end
are connected inversely.
Make sure sending end is
OTS102T and receiving end is
OTS102R.
RS485 does not work
Connecting terminal’s positive
and negative ends are
connected inversely.
Switch them.
