Bookham Technology will highlight its innovative LMC10 indium phosphide Mach-Zehnder modulated laser (InP MZ) 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 10Gbit/s is being overlayed on 2.5Gbit/s legacy spans for increased capacity

Transmitter modules extend reach of metro networks
Bookham, a provider of optical components, modules and subsystems, has achieved world record power performance with its latest range of transmitter modules.
Modulator and laser come together to save space
The LMC10NEH is an integrated 10Gbit/s InP MZ (Mach-Zehnder) modulator packaged with a high power CW laser.
Designed for 10Gbit/s applications, the product employs a high-power continuous-wave (CW) laser copackaged with an InP MZ modulator.
One of the key benefits of the product is its excellent optical signal to noise ratio (OSNR) performance compared with competing electroabsorption (EA) technology.
Exceeding 80km for dense wavelength division multiplexing (DWDM) applications at 10Gbit/s is difficult for commercial EA lasers.

The multimode laser diode allows service providers to extend triple-play service delivery to fibre customers located further away from the central office or the cable head-end.
Modulator tunes lasers up to 40Gbit/s
Reduced size InP MZ platform will allow Bookham to offer 40Gbit/s products in smaller footprints compared with existing 40Gbit/s offerings employing larger optics.
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 2.5Gbit/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 copackaging 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 due for 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 and 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.
