Toshiba Adds 2.5Gbps Small Form Factor Pluggable Transceiver Family For Short- And Intermediate-Range Optical Networks

Toshiba's broad line-up of 2.5Gbps Optical Modules now available in SFP configurations

Atlanta, GA., March 25, 2003 -- Toshiba America Electronic Components, Inc. (TAEC)* today announced a family of 2.5 gigabit per second (Gbps) small form factor pluggable (SFP) optical transceivers designed to provide an easy-to-use, cost-efficient, and space-saving solution for linking aggregated user traffic to high speed backbones. Developed by Toshiba Corp. (Toshiba), the multi-source agreement (MSA)-compliant transceivers are intended for use in short-, intermediate- and long range optical networks including metro and local area networks (MAN and LAN), synchronous optical network (SONET), synchronous digital hierarchy (SDH), storage area network (SAN), gigabit Ethernet (GbE) and Fibre Channel applications.

Toshiba's new hot-pluggable SFP transceivers include digital diagnostic capabilities to minimize downtime and enable systems to be maintained and upgraded without interfering with network operation. The transceivers provide designers with high performance from OC-3 to OC-48 data rates while utilizing a single +3.3V power supply.

"Toshiba is pleased to introduce this family of easy-to-use and maintain SFP modules with a broad selection of optics to enable our customers to increase port density in many short and intermediate range networks," said Jay Heinecke, director of business development for discrete devices at TAEC.

Toshiba's new SFP transceivers, designated the TOTR310P-D/DA, TOTR360P-D/DA, TOTR310P-F and TOTR210P, provide a selection of optics and transmission protocols to meet the implementation requirements of various high-speed optical networks.

The TOTR310P-D and TOTR360P-D are coarse wavelength division multiplexing (CWDM) modules that enable multiple channels to be aggregated onto one fiber. The TOTR310P-D provides four wavelengths and operates in the 1300 nanometer (nm) range using a Distributed FeedBack Laser Diode (DFB-LD). The TOTR360P-D CWDM module provides eight wavelengths and operates in the 1500nm range. These devices are available in the standard "D" configuration with PIN-PD connections or in a "DA" configuration with APD (avalanche photo diode).

The TOTR310P-F is a single-channel 2.5Gbps device with an integrated 1300nm Fabry-Perot laser diode (FP-LD), ideal for use in short and intermediate applications, and the TOTR210P SFP transceiver utilizes an 850nm Vertical Cavity Surface Emitting Laser (VCSEL), for greater value and efficiency in short-haul applications (up to 500 meters). These devices are ideal for low-cost applications.
