Sunrise Telecom's STT ONE module targets metro and core optical networks

October 26, 2005 San Jose, CA -- Sunrise Telecom has expanded its Scalable Test Toolkit (STT) platform with the addition of its Optical Network Expert (ONE) module. Designed to test next-generation SONET/SDH and optical transport networks (OTN), the company says its integrated STT ONE module allows technicians to perform a wide range of tests at virtually any location on an optical network.

October 26, 2005 San Jose, CA -- Sunrise Telecom has expanded its Scalable Test Toolkit (STT) platform with the addition of its Optical Network Expert (ONE) module. Designed to test next-generation SONET/SDH and optical transport networks (OTN), the company says its integrated STT ONE module allows technicians to perform a wide range of tests at virtually any location on an optical network.

According to the company, the installation and maintenance of OTNs requires a portable platform such as the STT ONE module that provides forward error correction and verifies conformance to the ITU-T G.709 recommendation, as well as a range of network performance standards including end-to-end connectivity at OTU1 (2.66 Gbit/sec) and OTU2 (10.7 Gbit/sec) bit rates, while completing asynchronous/synchronous mapping of SDH/SONET client signals. The company says that by integrating OTN and EoS (VCAT, GFP, and LCAS) testing into a single, compact unit, the module eliminates the need for multiple instruments.

According to the company, aimed at metro and core networks, the module's design allows it to operate bundled with other STT modules and managed by a single STT controller, or to operate fully as a standalone unit. In addition, the module can be installed on the customer's site for remote testing and monitoring through any LAN or WAN using an IP address.

The company says the module's high and low order virtual concatenation capabilities help end users to verify proper end-to-end connectivity for the selected containers. Differential delay detection and generation functions allow users to measure delay in the existing network and to stress the far end payload assembly circuitry by inserting a delay on each member, which the company notes must be properly reconstructed at the far end in spite of the delay of each member.

"In addition to being evaluated at a number of EoS and OTN field trials, it is particularly gratifying to announce that the STT ONE has been selected as the standard solution by Deutsche Telekom AG," reports Paul Chang, CEO of Sunrise Telecom.

The company says it has also received STT ONE orders from a number of Tier 1 service providers in Latin America, Asia, Europe, and Australia. The module is now available in production quantities.
