Opnext launches TXFP transceiver for 96 channels on full C-band, with flexibility to field re-tune any wavelength

At the European Conference and Exposition (ECOC 2011) in Geneva, Switzerland (19-22 September), optical module and component maker Opnext Inc of Fremont, CA, USA has announced the introduction and availability of its integrated tunable XFP (TXFP) transceiver, involving a demonstration highlighting automatic wavelength tuning designed to deliver stable wavelength control while supporting a wavelength range of 1529-1567nm.

Developed in collaboration with Hitachi's Central Research Laboratory (CRL), the TXFP pluggable transceiver is a hybrid design that combines the tunable laser and indium phosphide Mach-Zehnder (InP-MZ) chips to offer what is claimed to be superior optical shutter functionality. The TXFP transceiver delivers system performance to address mode-hopping for optimized wavelength stability in a variety of dense wavelength division multiplexing (DWDM) applications, says Opnext. In addition, the TXFP design can flexibly support negative-chirp or zero-chirp DWDM applications to replace DWDM-XFP or 300-pin tunable transponders.

“Opnext's tunable XFP transceiver has been designed to provide our customers with wavelength control and reliability in a smaller form factor where high port density is valuable,” says Tadayuki Kanno, president of Opnext’s modules business unit. “Using our own, in-house designed compact tunable TOSA [transmission optical sub-assembly], we're bringing a TXFP module to market that can support the growing demand for tunable DWDM technologies,” he adds.

Opnext expects its tunable XFPs to be in mass production in early 2012.
