24 Jan 2007 iTLA offering L-band capability with in-service power adjustment, and an iTLA bringing in-service power adjustment to existing C-band iTLA - designed to give vendors the flexibility and scalability they need to meet future network capacity demands. Two new versions of the Bookham fully-qualified LambdaFlexTM integrable Tunable Laser Assembly (iTLA) are launched today. The products – one a completely new iTLA offering L-band capability with in-service power adjustment, the second bringing in-service power adjustment to the existing C-band iTLA - are designed to give vendors the flexibility and scalability they need to meet future network capacity demands.
The new products build on the company’s proven fixed power C-band iTLA. Differentiated by its fast tuning speed, the iTLA is fully-qualified and in high volume production at the company’s manufacturing facility in Shenzhen, China. Based on the OIF MSA outline, the laser and control electronics are pre-mounted on a dedicated circuit board to ensure that customers can integrate the assembly with their systems as quickly as possible. The product provides a number of market-leading functions, such as narrow line width, internal frequency dither generation, direct input path for TX trace tone functionality, dark tuning and field programmable firmware.
Unlike many competing technologies, the Bookham tunable laser is built on a single InP optical chip with no moving parts – a design that is protected by US patent (US7145923). This enables extremely fast tuning times and ensures excellent reliability, comparable to that offered by legacy DFB lasers. It also brings cost-effective wideband tunability to long haul and regional metro applications.
The Bookham tunable portfolio is RoHS compliant.
