Tunable laser assemblies are more flexible
Bookham has launched two new versions of its fully qualified LambdaFlex integrable tunable laser assembly.

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.
The iTLA, which has already been extensively deployed in systems supporting 10Gbit/s and below, has now been selected for use in 40Gbit/s transmission systems, including the Mintera MI 40000XS next-generation subsystem for DWDM optical transport in metro, regional and ultra-long-haul telecom networks.
Mintera is currently shipping the MI 40000XS platform to customers worldwide.
"The Bookham iTLA has proved extremely effective in our next-generation 40Gbit/s DWDM optical transmission systems", says Bryan Siegal, VP Operations and Customer Satisfaction at Mintera.

The 2.2 x 3in footprint enables network equipment manufacturers to increase port density, placing two SFF transponders on a card where only one LFF would fit.
Bar supports laser systems
The VHB bar has a power output of 80W (up to four times the brightness of a typical 10mm bar) and measures only 3.2mm in width.
"We are very satisfied with the optical performance of the Bookham iTLA".
"It has provided us with a reliable, high performance laser source".
"The product's mechanical design means that it is easy to assemble, requiring no additional parts, thereby reducing the bill of materials".
"The full C band coverage has simplified our planning and inventory requirements".
Commenting on the announcement, Jon White, Product Line Manager for tunable sources at Bookham, says: "The Bookham iTLA has been designed to be a common base technology to enable bit rates up to and through 40Gbit/s".
"This approach has enabled us to provide a very cost-effective solution for our higher bit-rate customers without the need for further design changes".
"We are seeing significant market penetration with our tunable portfolio and we continue to demonstrate our capability to enable our customers' next-generation network architectures through qualified leading-edge technology and a high volume manufacturing capability".
Differentiated by its fast tuning speed to enable reconfigurable network features, the iTLA is fully-qualified and in volume production at the company's manufacturing facility in Shenzhen, China.
Based on the OIF MSA outline, the full-band tunable laser is supplied in module form, with control electronics and firmware, to enable customers to integrate the assembly with their systems quickly and economically.
The product provides a number of functions, such as narrow line width, internal frequency dither generation, direct input path for transmitter trace tone functionality, dark tuning, field programmable firmware, adjustable power and full C or L band coverage.
Bookham is also able to offer custom iTLA designs by exploiting its vertical integration capability.
Unlike many competing technologies, the Bookham tunable laser is built on a single InP optical chip, the DS-DBR, with no moving parts -- a design that is protected by US patent (US7145923).
This enables extremely fast wavelength tuning with excellent reliability, comparable to that offered by legacy DFB lasers.
It also brings cost-effective wideband tunability to all optical transport applications.
