SEPTEMBER 16, 2008 -- Bookham Inc. (search for Bookham) today announced that it has launched a DWDM SFP module that boasts a transmission speed of 5 Gbits/sec. 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 10-Gbit/sec DWDM XFP transceivers, say company representatives. 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 +3 dBm to +6 dBm, has channel spacing of 100-GHz, and offers full C- and L-band coverage.
Bookham says it has also achieved an uncompensated reach of 400 km at 2.5 Gbits/sec with a multi-rate DWDM SFP, continuing the evolution of the company's high-performance pluggable product range. The portfolio offers DWDM options for all transmission speeds and network protocols, including Ethernet, Fiber Channel, and SONET/SDH. All designs are underpinned by the same proven optical engines, says the company, including 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," reports vice president of 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 4-Gbit/sec Fiber Channel) and multi-rate (100-Mbit/sec to 2.7-Gbit/sec) variants as well as equivalent versions with higher optical power levels (5.5 dBm typical). All these parts are available in C- and L-band wavelengths. For 4-Gbit/sec Fiber Channel applications, Bookham says it has specific DWDM and CWDM parts targeted at 80-km point-to-point links. According to company representatives, this wide range ensures that Bookham is able to meet the demands of customers operating all WDM systems based on pluggable optics.
