T3 & E3 Data Transmission

Modems

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.

Features

System Design

• Meets Bellcore, ANSI T1.102, TR-TSY-000499/CCITT &

ITS G.703, T3 and E3 standards

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.

• Support AMI/B8ZS/HDB3 line code

• Multimode and singlemode operation over 2 fibers

• Built-in dry contact alarm relay

• Built-in self link tests diagnostic with indicators on the

front panel

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 +15V_DCor -48V_DC(option) built-in power source;

thereby providing versatility in system design.

• Retiming of receive signals for low jitter at both fiber and

coax ports

• Built-in Dual Power Redundancy

• Stand Alone unit or Rack Mountable
