TDM-300R Mux/Demux Optical Link – HD-SDI, SD-SDIpdf

The TDM-300R is a card for the Time Division Demultiplexing of multiple signals from one singemode fibre. Four serial digital video signals, (including one HD-SDI signal), can be electrically demultiplexed from the TDM-300T. Any embedded audio or other data embedded within the ancillary data space is passed transparently.
The TDM-300 links are ideal for tie-lines and Outside Broadcast applications and particularly suited to the PROBE portable fibre optic enclosures.

An electrical input to each card also allows the multiplexed TDM signal to be routed via a standard 3G-SDI routing and distribution network within a broadcast facility.
This is link selectable between the optical and electrical inputs.
By combining multiple or bidirectional TDM-300 links with standard BC Series cards complex optical networks can be realized in the most cost effective and compact footprint.

The TDM-300R occupies a single slot in the BC100-3RU 19″ rack-mounting frame allowing up to 15 channels of multiplexed video to be transmitted and received in a single 3RU frame.
Alternatively 6 cards can be housed in the compact BC-160 1RU. 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.

CWDM variants are available allowing up to 16 TDM links to be multiplexed together i.e. 16 x HD signals and 48 SD-SDI on one singlemode fibre.

The TDM-300R can also be housed in individual BC110/BC120 rugged enclosures.
