Luminent announces family of coarse wavelength division multiplexing modules

Luminent Inc. (Nasdaq:LMNE) announced the availability of a family of 4 channel and 8 channel Coarse Wavelength Division Multiplexing (CWDM) modules designed to address the needs of the Metro Optical Ethernet market.

Luminent's CWDM products provide optical networking equipment manufacturers a tool to support the unceasing demand for higher bandwidth equipment build-outs in the enterprise access and metropolitan area networks.

The 4 channel modules multiplex four DFB Lasers in the 1500 nm window to provide a family of products carrying aggregate data rates of 2.5 Gb/s, 5 Gb/s, 10 Gb/s and 12.5 Gb/s. These 4-channel CWDM modules support a variety of link budgets: from 3 dB to 20 dB.

This technology provides an economical approach to implementing 10 Gigabit Ethernet in the MAN by supporting 10 km to 70 km solutions over existing installed single mode optical fiber.

To achieve these distances, Luminent is using CWDM with 20 nm channel spacing in the low loss 1500 nm transmission window. This spacing allows for un-cooled laser operation, a high yield manufacturing process, and lower cost mux-demux technology; thus providing a complete cost effective solution for various data and telecom applications.

The 8-channel module will offer similar speed and link budget characteristics.

Luminent is currently shipping this family of modules in volume to leading manufacturers in the Metro Access space.

Luminent is developing similar CWDM solutions to meet various data rates and link budgets in the 1300nm transmission window over single mode optical fiber. Luminent also plans to support designs meeting proposed IEEEI10 Gb standards.
