Bookham plans full-band 10Gb/s long-reach tunable pluggable transceiver

At last week’s European Conference on Optical Communications (ECOC 2007) in Berlin, Germany, optical component, module and subsystem maker Bookham Inc of San Jose, CA, USA announced that it is developing a full-band 10Gb/s, long-reach, tunable pluggable transceiver, for commercial availability in first-half 2008.  

The new product will combine the firm’s indium phosphide (InP) DS-DBR (digital supermode-distributed Bragg reflector) tunable laser and Mach-Zehnder (MZ) modulator with an avalanche photodiode ( APD) receiver in a pluggable Super X2 format. It will offer the existing benefits of tunability combined with the ‘pay as you grow’ convenience of a hot pluggable module, says the firm.

“The industry has long recognised the advantages of tunable technology and the flexibility of front-panel pluggable modules; this new product will combine both benefits,” says Jon White, product line manager of the firm’s InP MZ and tunable portfolio.  

“Our ownership of the core InP chip technology and our heritage in MZ modulators, monolithic tunable lasers and pluggable optics means that we are well positioned to make the tunable pluggable ideal a workable, reliable reality,” White claims. “We are also working towards next-generation tunable TOSA (transmit optical subassembly) components that will enable further size reduction.”
