Atoga rows TDM waters with OAR

Atoga Systems is looking to makes its products capable of delivering time-division multiplexing services directly off carriers' metropolitan fiber networks.

The company is introducing TDM customer ports for its Optical Application Router (OAR). Called OAR5i, the device can deliver 45M bit/sec DS-3 connections to customers via single-port cards for the OAR5 chassis. In the third quarter, the company will introduce a six-port, 155M bit/sec OC-3 card. Previously, the device supported only Gigabit Ethernet customer ports.

Also in the third quarter, the company says it will partner with another vendor for a separate box with DS-1 and DS-0 ports to deliver lower-bandwidth 1.5M bit/sec and 64K bit/sec services to customers. This separate device will aggregate traffic onto larger uplinks to an OAR5i, the company says.

OAR5 combines the functions of an IP router, a SONET add-drop multiplexer and dense wave division multiplexing (DWDM). Customer traffic is loaded onto SONET frames and placed on wavelengths in metro service provider networks. OAR5 devices support DWDM, which enables multiple wavelengths on a single fiber. OAR5 also uses tunable lasers, so extra wavelengths can be turned on quickly as needed.

Atoga OAR5i is available in the third quarter. A base system with 16 ports of 10/100M bit/sec Ethernet and six OC-3 interfaces with a fixed OC-48 laser costs $60,000. With a second laser it costs $90,000. With one tunable laser it costs $80,000, and with two tunable lasers costs $120,000.
