User Manual  


The DTR-1000 is a multi-channel transmitter / receiver unit designed principally for use as an up to sixteen serial data + Ethernet fibre optic transmission link on a single fibre for 3G-SDI, HD-SDI or SD-SDI applications conforming to SMPTE standards 424M, 292M and 259M-C using 9/125 µm single mode fibre.

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.

The Ethernet port conforms to the IEEE 802.3i, 802.3y and 802.3ab standards for Ethernet over CAT-5 cable, and the IEEE 802.3z (1000 Base-X) standard for Gigabit Ethernet over optical fibre.

The Ethernet port has automatic MDI/MDI X detection, this detects whether the Ethernet interconnect cable is a straight through or cross over type and automatically switches itself to accommodate, and will automatically select the link speed of the connected network (10/100/1000 Mb/s).

The optical port uses an internal course wave division multiplexer (CWDM) unit to combine the individual signals together allowing up to almost 50Gb of data to be transmitted over a single fibre.

Monitoring is possible locally via the front panel display or remotely via a web browser.

Power is supplied by an internal AC input power supply, with two secondary external +12Vdc input ports provided for power supply redundancy (external power packs sold separately).

The DTR-1000 is designed to be operated as a transmit/receive pair and is orderable as either a 16-channel transmitter only; a 16-channel receiver only; a 12-channel transmitter + 4-channel receiver; a 12-channel receiver + 4-channel transmitter; an 8-channel transmitter + 8-channel receiver; an 8-channel receiver + 8-channel transmitter; an 8-channel transmitter only; an 8-channel receiver only; a 4-channel transmitter + 4-channel receiver; or a 4-channel receiver + 4-channel transmitter. All models come with the bi-directional Ethernet port.

The DTR-1000 comes as a 1RU enclosed chassis with all signal and power connections on the rear.
