BC340R Single Channel Optical to Electrical Converter HD-SDI, SD-SDI, ASIpdf

The BC340R is a receiver for the conversion of optical signals into electrical HD-SDI, SD-SDI and ASI. The incoming optical signal is fed to a trans-impedance and limiting amplifier before being electrically reclocked on the outputs. All Bluebell cards are designed to retain maximum integrity of the signal path offering excellent jitter free optical transport. Careful attention has been paid to reduce thermal runaway, eliminating the need for forced air cooling as fan failure and overheating is the most common cause of failure in modern electronic systems.

Two serial digital signals are available on the output. The BC340R is available in multimode, singlemode, WDM and CWDM variants to suit any fibre application.
The BC340R occupies a single slot in the BC100-3RU 19" rack-mounting frame which can hold up to 15 single slot cards. Some BC Series processing cards have dual functionality allowing up to 30 channels of video to be transmitted or received from a single 3RU frame.
Signal and card monitoring is achieved through SNMP monitoring in the BM101 network card.
Alternatively GP-Output alarms can be triggered via the BM100 module.

For stand alone applications the BC340R can be housed in an individual rugged enclosure.
