of interfaces are very simple to install and this Quick Start Guide should provide sufficient information to
get you up and running in the vast majority of cases.
Should you need additional information, an Operation Guide with full technical information is available
on request.

Overview:
The BC313 Series is a range of compact, stand-alone fibre interface modules intended for OB
applications, which allow SDI video to be transmitted over fibre-optic cable.
This Quick Start Guide covers four models making up the range:
• BC313T transmitter – single channel, SDI input, single fibre output
• BC313T/L transmitter – as BC313T, but with loop-through video output
• BC313R receiver – single channel, single fibre input, SDI output
• BC313R/D receiver – as BC313R, but with second (buffered) SDI output
The four models are of identical construction, and in outward appearance differ only in the silk-screened
labelling on the module:

Power supply:
All BC313 models require an external power supply voltage between 4.5 and 17 V. A Bluebell Model
PS12 PSU (12 V) will be packed with the interface if one was ordered. The power supply connector is a
Neutrik®XLR4M, and a locking mating connector is pre-fitted to the PS12 DC cable.
Inputs and outputs:
Video:
BC313 interfaces are intended for use with serial digital video signals with data rates up to 3 Gb/s.
Standards supported are SD-SDI (SMPTE 259M-compliant), HD-SDI (SMPTE 292M-compliant) and
3G-SDI (SMPTE 424M-compliant); ASI baseband streams are also compatible.
Videoinputs andoutputsareon75ohm BNCsockets.The BC313T andBC313Rhaveasingleconnector,
for video input or output respectively.
The BC313T/L has a second BNC, which is a “loop-through” of the input signal. This signal is equalised
and reclocked.
The BC313R/D also has an additional BNC connector, in this case an independently-buffered second
output, enabling the interface to feed two different destinations.
Optical:
A dual LC optical SFP connector is fitted as standard; only the upper optical port is active (BC313 units
are unidirectional). If specified at the time of ordering, an ST optical connector may be fitted instead.
Single-mode operation is standard; alternative multi-mode versions of each model are available. The
standard transmission wavelength for single-mode versions is 1310 nm; a version with an alternative
wavelength (1550 nm) is also available. Transmitters fitted with lasers tuned to specific CWDM
wavelengths are also available. Any of the alternative options will have been specified at the time of
order.
Note that the optical receivers in the BC313R and BC313R/D are wideband, and can be used with all
wavelengths in the range 1270 – 1610 nm.

Using the BC313:
Normally, BC313 units will be used in pairs, with a BC313T (or BC313T/L) and a BC313R (or BC313R/D)
at the ends of the fibre run.

LEDs:
Bi-colour LEDs are fitted adjacent to each of the primary SDI video BNC input or output connectors; they
are not fitted to the loop-through output on the BC313T/L or the second output on the BC313R/D. These
illuminate green to confirm a valid input signal, or red to indicate either no signal or a signal which is in
some way invalid. On a BC313T and BC313T/L, the LEDs monitor the incoming SDI video signal (but see
note re jumpers below), on a BC323R and BC313R/D, they confirm the receipt of a valid optical signal.
Reclocking:
The factory default is for the data at all the inputs (SDI or optical) to be internally reclocked. This will
generallybedesirablefor themajorityofoperationalsituations.Thereclockingcircuitrymaybebypassed
on a per-channel basis by moving internal PCB jumpers; this may be desirable when low data rates or
asynchronous operation are in use. Please consult the Operation Guide for details of how to do this.
SDI LED detection source:
Each transmission channel (i.e., in the BC313T and BC313T/L) has an additional jumper which sets
the source signal for triggering the bi-colour LED. The default setting is for the LED to confirm a valid
SDI stream, but this may be altered to monitor the amplitude of the incoming signal, in which case a red
illumination indicates that the signal level is too low for data recovery to be made.
