Picolight Inc. has introduced the first of what is expected to be a broad family of 1.315m long-wavelength optical transceivers for metropolitan applications. The PL-XPL-00-L13 SFF pluggable transceiver is the initial device in the Extensus family. The series will begin with transceiver modules that use Fabry-Perot lasers, but will eventually include parts with VCSELs operating natively in 1.315m realms, the company said.

The initial Extensus device has a data rate range of 1Gbps to 1.25Gbps, meeting specs for both Fibre Channel and Gigabit Ethernet 1,000Base-Lx applications. Warner Andrews, Picolight's vice president of marketing, said the lasers' cost advantage will help them to displace both Fabry-Perot and some distributed-feedback lasers, particularly in cost-sensitive metro-radius applications, such as Ethernet in the first mile.

The company expects to roll out in rapid succession pluggable transceivers meeting 2.5Gbps rates, and modules designed for 10Gb rates in both OC-192 SONET and 10Gb Ethernet applications. Once the series of standard serial products is fleshed out, Picolight will expand Extensus through 12-channel VCSEL-based devices. The company is confident it will be able to add 1.315m VCSEL products soon; as it tested 1.285m lasers last fall.

By 2003, Picolight executives predict, laser transceivers in enterprise-level packages, offered at LAN price points, will be able to reach distances of 10km and 20km. The Extensus transceivers will use the same hot-pluggable package configuration with wire bail, allowing ports in a 32- or 64-channel concentrator to be brought up as needed.

The PL-XPL-00-L13 is sampling now, with volume production slated for the second quarter. The price in quantities of 1,000 is $150 per transceiver.
