Overview
Thank you for purchasing this Bluebell Opticom professional broadcast video product. If you
are new to Bluebell products, or to the subject of transmitting video and/or other types of signal
over fibre links, please take the time to read through this document before putting the module
to use.
Introduction
The BC368 and BC368D plug-in modules belong to the Bluebell Opticom
BC Series of modular fibre interfaces, designed primarily for Outside Broadcast (OB) and
studio applications. The modules are equipped with two empty SFP carriers: the BC368 is
configured for two transceiver cartridges each with an input (Rx) and an output (Tx), while
the BC368D is configured for one dual-channel receiver cartridge (dual Rx) and one dual-
channel transmitter cartridge (dual Tx). These will generally be fibre-optic cartridges of the
user’s choice, though compatible cartridges with coaxial or other types of connector may be
installed if wished. Single-channel cartridges may be installed in either module type if only one
signal path is required.
Fitting suitable SFP cartridges to the two carriers allows the modules to perform a variety
of optical/optical (or optical/copper) operations often needed in OB and other broadcast
situations. These include bidirectional format conversion, signal monitoring and wavelength
management(conversionbetweenoptical wavelengths),andthus theBC368 andBC368Dcan
be regarded as useful engineer’s “toolkit” items as well as forming part of a fixed installation.
The BC368 and BC368D are intended for use with SDI video signals (12G, 6G, 3G, HD or SD)
or DVB-ASI video signals. MADI, audio and Ethernet signals at bitrates between 150 Mbps to
11.88 Gbps are also supported.
Physical formats
BC368 and BC368D modules fit the Bluebell BC100 or BC160 19” modular frames. The
frames can house fifteen (BC100) or six (BC160) interface modules, and are fitted with dual
internal AC power supplies.
Alternatively, modules may be fitted into smaller aluminium chassis; the BC101 and BC102
hold one and two modules respectively and require an external DC power source, while the
BC120 holds three modules and has an integral mains PSU.
BC368 and BC368D modules are fitted with two SFP carriers. These will typically be fitted (by
users) with dual fibre optic cartridges, but cartridges with copper connectivity may be fitted
alternatively: options include composite video, SDI, HDMI and DVI.
For fibre optic implementation, singlemode operation will normally be at 1310 nm or
1550 nm; alternative CWDM grid wavelengths are also possible. The optical option is generally
specified at the time of order.

Power requirements
Power supply requirements are dictated by the enclosure type used.
BC100 modular frames:
These may be fitted with either one or two AC mains PSU modules (number specified at time of
order). Each module has sufficient capacity to power a fully-loaded frame. TheAC connection
is via standard IEC cables, DC power distribution inside the frame is via the motherboard. See
the Operation Guide supplied with the frames for more details.
BC160 modular frames:
These are fitted as standard with dual internal AC mains power supplies, each of sufficient
capacity to power a fully-loaded frame. The AC connection is via standard IEC cables, DC
power distribution inside the frame is via the motherboard. See the Operation Guide supplied
with the frames for more details.
BC101 and BC102 single- and dual-slot chassis:
These are supplied with an external Universal AC adaptor which connects to the chassis via a
flying lead terminated in a 4-pin locking XLR connector. Mains is via an IEC connector.
BC120 triple-slot chassis:
This housing for three plug-in modules is fitted with an internal AC mains supply; mains
connection is via a rear IEC connector.

Choice of SFP types will
determine module's
functionality.
Example SFP
1. SFP1 — SFP carrier for signal-pair 1. User’s choice of transceiver cartridge may be fitted.
The arrowheads adjacent to the carrier indicate the transmit and receive connectors -
the lower optical connector is “receive”, that is, an input to the module, while the upper
connector is “transmit”, an output from the module.
2. SFP2 — SFP carrier for signal-pair 2. Details as [1].
3. S/L (SFP 1) — bi-colour LED for received input signal status at SFP 1. The LED illuminates
green to indicate that a valid input signal is detected at the SFP1 Rx port, and red when no
valid signal is detected.
4. S/L (SFP 2) — bi-colour LED for received input signal status at SFP 2. Details as [3].
5. PW — green LED; illuminates when DC power is applied to the module.

Example SFP
6. SFP1 — SFP carrier for two input signals. User’s choice of single or dual receiver cartridge
may be fitted. The arrowheads adjacent to the carrier indicate the direction of signal flow.
7. SFP2 — SFP carrier for two output signals. User’s choice of single or dual transmitter
cartridge may be fitted. The arrowheads adjacent to the carrier indicate the direction of
signal flow.
8. PW — green LED; illuminates when DC power is applied to the module.
BC368-OperationGuide-v1 8
Signal Routing
BC368 only:
Both SFP 1 and SFP 2 must be fitted with transceiver cartridges. The signal at SFP 1’s input
(the lower optical connector of the pair) will always be available at SFP 2’s output (the upper
optical connector of the pair). A second, symmetrical signal path is available in the opposite
direction, as the diagram below shows:

Thereceivers in fibre-opticSFPtransceiver cartridges arewideband;the BC368 maytherefore
be used to retransmit a signal at a different optical wavelength from the one it is received at.
This principle may, of course, be extended to two separate signals by using both signal paths.
If one transceiver is fitted with “copper” connectivity (e.g., SDI, HDMI, etc.), one optical signal
appliedtothemodulemaybeconvertedintoelectricalformatwhileanotherinthecorresponding
electrical format is remodulated as an optical output.
BC368-OperationGuide-v1 9
BC368D only:
SFP 1 must be fitted with a receiver cartridge and SFP 2 must be fitted with a transmitter
cartridge. The BC368D is configured for two separate, identical signal paths between the two
SFPs; dual channel cartridges will need to be fitted in both carriers to take advantage of this.
However, single channel cartridges may be fitted if only a single signal path is needed. The
signal paths are shown in the diagram below:

The receivers in fibre-optic SFP cartridges are wideband; the BC368D may therefore be used
to retransmit a signal at a different optical wavelength from the one it is received at. This
principle may, of course, be extended to two separate signals by using both signal paths.
If one SFP is fitted with “copper” connectivity (e.g., SDI, HDMI, etc.), optical signals may be
converted to or from electrical format.
BC368-OperationGuide-v1 10
SDI format compatibility
BC368 and BC368D interfaces are intended for use with serial digital video (SDI) signals at
data rates up to 11.88 Gb/s. Standards supported are:
• SD-SDI – SMPTE 259M-compliant at 270 Mb/s
• HD-SDI – SMPTE 292M-compliant at 1.483 and 1.485 Gb/s
• 3G-SDI – SMPTE 424M-compliant at 2.967 and 2.970 Gb/s
• 6G-SDI – SMPTE ST-2081 compliant at 6 Gb/s
• 12G-SDI – SMPTE ST-2082 compliant at 12 Gb/s
ASI baseband streams at 270 Mb/s are also compatible.
Signals at these standards will be passed through the cards to the other SFP. On the BC368,
the relevant status LED(s) will illuminate green on receipt of a valid signal.
The BC368 and BC368D will also pass signals at other bit rates, such as MADI at 125 Mb/s
and other digital video formats at 143 Mb/s, 177 Mb/s, 360 Mb/s, and 540 Mb/s. They will also
pass digital audio signals and Ethernet data up to 10 gigabit.
BC368 and BC368D SFP combinations
The BC368 and BC368D are format converters whose functionality and application will always
be determined by the type of cartridges fitted into the two SFP carriers. While the modules will
generally be used with fibre optic cartridges, several other types exist and are compatible with
the module.
The table on the following page illustrates some possible combinations of input and output
formats. On the BC368, the cartridges in both carriers (SFP 1 and SFP 2) must be bidirectional
transceivers; on the BC368D, one cartridge (SFP 1) must be a single- or dual-channel receiver
and the other (SFP 2) a single- or dual-channel transmitter.
