SDI-EO-2 /SDI-EO-2-RC Rev. 2
1Product overview
The Flashlink SDI-EO-2 /SDI-EO-2-RC is an electrical to optical converter
module providing high performance media conversion for various signal
formats from 19.4Mbps up to 540Mbps. Unmatched signal accuracy, even in
critical applications with pathological signal patterns makes the SDI-EO-2 /
SDI-EO-2-RC the first choice for all optical transport demands.
There are two versions of this product, SDI-EO-2 and SDI-EO-2-RC. SDI-EO-2-
RC has reclockers for each channel and cross point functionality. SDI-EO-2
comes without the reclockers and the cross point switch.
The SDI-EO-2 / SDI-EO-2-RC can transport all SD signal formats in addition to
DVB-ASI and SMPTE 310. It performs optical refreshing. High quality optical
transmitters using Fabry-Perot lasers are suitable short and medium haul
applications. The open system platform of Network Electronics Flashlink
system allows easy interoperability with third party fibre optical systems.
The SDI-EO-2 / SDI-EO-2-RC unit has also one electrical output for each
channel, which reduces the need for additional DAs. The electrical input is
equipped with a multi rate cable equaliser providing an equalisation of
typically 300m of high quality coax cable at 270Mbps.

reclockers are not implemented in SDI-EO-2.

3Format configuration
The SDI-EO-2 can support a number of different broadcast formats. The
correct configuration can either be set with DIP switch or with the GYDA-SC
System Controller. The layout of SDI-EO-2 is shown in the drawing below with
the DIP switch to the upper left position.
Figure 2: SDI-EO-2 board layout.
DIP switch configuration must be set according to the table below:
Switch # Label Function, DIP = ON Function, DIP = OFF Comment

All DIP switches are off when pointing towards the release handle.
The SWP DIP switch sets normal mode(input 1 to output 1 and input 2 to
output 2) or crossed mode (input 1 to output 2 and input 2 to output 1).
GYDA-SC System Controller can set other combinations like duplication of
either input channel to both output channels.

4Connector module
The SDI-EO-2 / SDI-EO-2-RC has a dedicated connector module: HD-EO-2-C1.
This module is mounted at the rear of the frame. The module is shown in the
figure below.
Figure 3: Connector module for SDI-EO-2.
In typical use, a SDI-EO-2(-RC) / SDI-OE-2(-RC) module at each end will be
used. Two channels can simultaneously be converted from optical to electrical
channels. The electrical input signal is connected to the INx input on the
transmitting SDI-EO-2(-RC), and the electrical output is connected to the
corresponding OUTx+ or OUTx- output BNC on the receiving SDI-OE-2(-RC).
The fibre cable is connected to the corresponding optical port (OPT1 uses
IN1/OUT1- and OUT1+ and OPT2 uses IN2/OUT2- and OUT2+).
4.1 Mounting the connector module
The details of how the connector module is mounted, is found in the user
manual for the Flashlink frame FR-2RU-10-2.
This manual is also available from our web site:
