Full Duplex DS-3 Modem T3 & E3 Data Transmission

The DS-726/T3 and DS-726/E3 are full duplex transmission systems—a T3-Carrier at 44.735 Mbps and E3-Carrier at 34.368 Mbps. A pair of DS-726/ T3 modems with interconnecting optical cables provides versatile, low cost, high speed, error-free data communication between terminals for a distance of up to 25 km.

The DS-726/T3 and E3 use a highly linear stage to transmit data rates at 44.736 Mbps over a multimode fiber optic cable. The wide optical dynamic range of the DS-726/T3 allows various optical cable core sizes and lengths to be used. The transmission distance can vary from a few feet up to 30 km without causing optical receiver overload.

System Design

On the receiver side, an integral detector amplifier is used to ensure low noise/high sensitivity reception. Signal quality is monitored by measuring the transmit data input level and the received optical signal strength. A built-in alarm dry contact relay as indicator when signal drops below a pre-determined level.

Wall mounts and rack adapters are available for remote stand alone unit installation. In addition, the DS-726/T3 transmitter and receiver can be powered from a +15VDC or -48VDC (option) built-in power source; thereby providing versatility in system design.
