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 TDM signal routed via a standard 3G-SDI routing and distribution network to be demultiplexed 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. 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 an individual BC110 rugged enclosure.
