Transceiver speeds up transmission in multiple networks

Bookham Inc. has started sampling a dense wavelength division multiplexing (DWDM) small form-factor pluggable (SFP) module that boasts a transmission speed of 5Gbit/s and claimed that a multirate 2.5Gbit/s variant has achieved an uncompensated reach of 400km.

The transceiver, which Bookham said is the fastest DWDM SFP module today, is created to work in high-noise, amplified environments, and is aimed at multispan links for metro networks.

The module delivers an output power from +3dBm to +6dBm, with a channel spacing of 100GHz and offers full C and L band coverage.

"We are continually developing the performance of our pluggable modules to retain our technology position in the pluggable wavelength division multiplexing (WDM) sector and meet the breadth of demands from our customer base," said Yves Le Maitre, VP, telecom sales, Bookham.

"The highest speed and the longest reach in SFP WDM pluggable optics, along with outstanding stability and tolerance to low optical signal noise ratio links, is a great achievement for the design team," she added.
