Transmitter Modules provide 10 Gb/s transmission.

Press Release Summary:

Utilizing indium phosphide Mach-Zehnder-based modulator and distributed feedback laser, Models LMC10NEJ and LMC10ZEG allow users to extend reach of metro networks to 100 km, while retaining small form factor or equivalent footprint areas with no electronic dispersion compensation or dispersion compensated fiber. Model LMC10NEJ features negative chirp and precision optical power, while Model LMC10ZEG provides zero chirp and dynamic power control.

Bookham Achieves Record Power Output With New Transmitter Portfolio

San Jose, CA - September 22, 2005 - Bookham, Inc. (NASDAQ: BKHM), a leading provider of optical components, modules and subsystems, has achieved world record power performance with its latest range of transmitter modules. The new products are believed to be the first to offer 100km Mach-Zehnder (MZ) long-reach, with 10Gb/s transmission, in a package small enough to enable SFF (small form factor) module footprints.

The transmitters are 10Gb/s devices utilising an indium phosphide (InP) MZ based modulator and a distributed feedback (DFB) laser. The devices allow customers to extend the reach of their metro networks, enabling long reach capabilities, while retaining SFF or equivalent footprint areas with no Electronic Dispersion Compensation (EDC) or Dispersion Compensated Fiber (DCF). This means that a 10G overlay strategy can be implemented on existing 2.5G networks without compromising the density of metro shelves.

"No other 10Gbit/s device has the same performance and size combination," said Jon White, product line manager at Bookham. "Take-up for our existing InP transmitters has soared over the last year; these new versions are being offered to a wider customer audience as capacity increases in our new assembly facility in China.

"The products offer customers more choice in terms of transmitter options and reinforce our commitment towards making InP transmitters an industry standard in optical telecommunication."

The LMC10NEJ, with negative chirp and precision optical power, and the LMC10ZEG, with zero chirp and dynamic power control, are both Telcordia qualified and are moving into full-scale production. The new transmitters join the already successful LMC10NEG.

The products form part of Bookham's transmitter and network laser portfolio and complement the company's range of directly modulated lasers (DML) and electro absorption (EA) lasers. Bookham is also developing fullband tunable versions of its compact MZ products, which are planned for release in 2006.
