BC625-OperationGuide-v2 5
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 audio or other types of signals
over fibre links, please take the time to read through this document before putting the BC625
to use.
Introduction
The BC625 plug-in card belongs to the range of the Bluebell Opticom BC Series modular
fibre interfaces, designed primarily for Outside Broadcast (OB) applications. It is a 4-channel
transceiver, permitting transport of four analogue audio signals in each direction between two
locations remote from each other over a dual-fibre optical link.
As they are transceivers, BC625 cards will normally be used in pairs.
Physical formats
BC625 cards fit the Bluebell BC100 or BC160 19” modular frames. The frames can house
six (BC160) or fifteen (BC100) interface cards, and are fitted with dual internal AC power
supplies. Alternatively, cards may be fitted into smaller aluminium chassis; the BC101 and
BC102 hold one and two cards respectively and require an external DC power source, while
the BC120 holds three cards and has an integral mains PSU.
All plug-in cards are fitted with cartridge-style SFP dual fibre transceiver modules; both
single-mode and multi-mode versions are available. Single-mode operation will normally be
at 1310 nm or 1550 nm; alternative CWDM grid wavelengths are also possible. The optical
option must be specified at the time of order.
Power requirements
For all versions, power supply requirements are dictated by the enclosure type used.
BC-100 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 User Guide supplied with the frame units for more details.
BC-160 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 User Guide supplied with
the frame units 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 cards is fitted with an internalAC mains supply; mains connection
is via a rear IEC connector.
