Bookham Announces 5Gb/s DWDM SFP

Pluggable portfolio achieves 400km reach with 2.5Gb/s variant

SAN JOSE, Calif., Sept. 16 -- Bookham, Inc. (NASDAQ:BKHM) has launched a DWDM SFP module that boasts a transmission speed of 5Gb/s. The high-speed module will enable customers to expand the performance of SFP-based board designs, and offers a readily available, cost-effective alternative to 10Gb/s DWDM XFP transceivers. The transceiver is sampling into customer premises now.

The transceiver, which Bookham believes to be the fastest DWDM SFP module available, is designed to operate in high-noise, amplified environments, and is targeted at multi-span links for metro networks. The module can deliver output power from +3dBm to +6dBm, has channel spacing of 100GHz and offers full C and L band coverage.

Bookham has also achieved an uncompensated reach of 400km at 2.5Gb/s with a multi-rate DWDM SFP, continuing the evolution of the company's high-performance pluggable product range. The portfolio offers DWDM solutions for all transmission speeds and network protocols, including Ethernet, Fiber Channel and SONET/SDH. All designs are underpinned by the same proven optical engines: the Bookham Avalanche Photodiode (APD) Receiver and buried-heterostructure directly modulated laser.

"We are continually developing the performance of our pluggable modules to retain our leading technology position in the pluggable WDM sector and meet the breadth of demands from our customer base," said VP Telecom Sales, Yves Le Maitre. "Boasting the highest speed and the longest reach in SFP WDM pluggable optics, coupled with outstanding stability and tolerance to low OSNR links, is a great achievement for the design team. We are confident that we can continue to grow our market share in this highly competitive space."

In addition to these transceivers, the Bookham WDM SFP portfolio offers standard optical power devices in both multi-protocol (SONET, Ethernet and 4Gb/s Fiber Channel) and multi-rate (100Mb/s to 2.7Gb/s) variants as well as equivalent versions with higher optical power levels (5.5dBm typical). All these parts are available in C- and L-band wavelengths. For 4Gb/s Fiber Channel applications, Bookham has specific DWDM and CWDM parts targeted at 80km point-to-point links. This wide range ensures that Bookham is able to meet the demands of customers operating all WDM systems based on pluggable optics.
