Bookham to Highlight Leading InP Technology at ECOC 2004

Abingdon, UNITED KINGDOM


ABINGDON, United Kingdom, Sept. 3, 2004 (PRIMEZONE) -- Bookham Technology plc, ("Bookham") (LSE:BHM) (Nasdaq:BKHM), a leading provider of optical components, modules and subsystems, is to highlight its innovative indium phosphide Mach-Zehnder modulated laser (InP MZ) LMC10 at the 2004 European Conference on Optical Communication (ECOC) in Stockholm, Sweden.

On display for the first time in Europe, the LCM10 product range has been designed to meet present and future market requirements for regional metro applications, particularly where 10Gb/s is being overlayed on 2.5Gb/s legacy spans for increased capacity. Designed for 10Gb/s applications, the product employs a high power Continuous Wave (CW) laser co-packaged with an InP MZ modulator.

One of the key benefits of the product is its excellent optical signal to noise ratio (OSNR) performance versus competitive Electro Absorption (EA) technology. Exceeding 80km for Dense Wavelength Division Multiplexing (DWDM) applications at 10Gb/s is difficult for Commercial EA lasers. In contrast, Bookham's InP MZ provides performance similar to Lithium Niobate modulators with reaches beyond 100km without any dispersion compensation, making it highly attractive for overlaying legacy 2.5Gb/s links. Unlike Lithium Niobate however, the unrivalled small footprint of the Bookham InP MZ allows it to be used in system shelves commonly employing directly modulated laser technology. This means metro bay density is not compromised.

"A key advantage to the LMC10 is its size, we have worked hard to meet our customers demands for more compact products," said Adam Price, Bookham's product line manager for the InP MZ portfolio. "Through a novel co-packaging technique we have created a package no bigger than a typical directly modulated laser. We believe that InP MZ development could help pave the way to smaller high performance optics."

The fully Telcordia qualified product range is now in high volume production and is anticipating a significant production ramp as the market moves through the second half of 2004.

Within Q3 this year, Bookham plans to add functionality to the product with the inclusion of an integrated Variable Optical Attenuator (VOA) and power monitor. With this increased functionality the product range will target long haul applications in addition to its core customer base of regional metro. Bookham continues to invest significantly in future R&D and operational capacity in the LMC10 product range and will be updating the market with significant added features to the product later this year.
