- Passes SMPTE 259M 270 Mb/s SDI pathological test sequence.
- LED indicators and external alarm contacts.
- Fibre, video and alarm connections at rear.
- Optional plug-in SNMP monitoring module.
- Eliminates ground loop problems.

The IRT DDT-4210 transmitter and DDR-4211 receiver are modules designed principally for use as a 270 Mb/s SMPTE/EBU serial digital video fibre optic transmission link, using 9/125µm single mode fibre, with optical paths losses up to 31dB.

The transmit / receive system specifications apply to all signal conditions, including the SMPTE 259M pathological test sequence.

In addition, the link may be used for ASI transport streams for use with MPEG compressed video streams or other 270 Mb/s type data. On board links may also be set to transport STM-1 (155 Mb/s) type signals.

The transmitter features automatic input cable equalisation and a choice of plug-in LASER modules of various wavelengths (ordered separately).

LED indicators are provided for digital signal presence, DC power and LASER output power out of range.

The DDR-4211 receiver uses a PIN photodiode detector with signal conditioning and reclocking circuits. The data rate is factory set for 270 Mb/s operation. Link settings allow STM-1 data rates (electrical and optical) to be set for interfacing with IRT's STM-1 interface cards.

Two serial digital outputs are provided. LED indicators are provided for digital signal presence and power.

Relay contact outputs are also provided for external use of alarm signals on both modules.

An optional SNMP (Simple Network Management Protocol) plug-in module is available, for each unit, for remote monitoring when used in conjunction with IRT's 4000 series frame fitted with SNMP capability.

The DDT-4210 and DDR-4211 are Eurocard modules designed to fit IRT's standard Eurocard frames as well as IRT's 4000 series frames for use with IRT's SNMP system and may be used alongside any other of IRT’s analogue or digital Eurocards.
