Santur intros low-profile tunable transmitter engine

FEBRUARY 19, 2008 -- The low profile and compact footprint make these 10-Gbit/sec tunable transmitter engines ideally suited for use in SFF transponders and XFP-E pluggable transceivers, say company representatives.

FEBRUARY 19, 2008 -- Santur Corp. (search for Santur), manufacturer of high performance parallel array devices for the global telecommunications industry, has announced development of a low profile version of its 10-Gbit/sec tunable transmitter engine, the TLMZ-LP.

According to Santur representatives, the TLMZ-LP integrates the company's market-leading tunable laser with an Indium Phosphide Mach-Zehnder modulator. These products have been engineered for either metro or long-haul transmission requirements. Both zero-chirp or chirped versions of the TLMZ-LP are available. Their low profile and compact footprint make them ideally suited for use in SFF transponders and XFP-E pluggable transceivers, says the company. This brings tunability into metro access networks and doubles the port density in the metro core networks.

"At Santur, we are very pleased with the development of the tunable transmitter product lines based on our parallel photonic array technology," contends Paul Meissner, CEO of Santur. "We value the partnerships we have developed with our customers and are moving forward with them on the next-generation solutions."

"Integration of the tunable laser with the Mach-Zehnder modulator in the low profile compact footprint package allows tunable transceivers to be used in the pluggable XFP-E format," adds Bardia Pezeshki, CTO and founder of Santur. "Further, it eliminates the need to source a separate tunable laser and modulator. It also eliminates the need for polarization maintaining fiber and a splice or connector between the laser and modulator," Pezeshki reports.

Santur is currently sampling these devices to customers and expects to be in volume production during Q3 of 2008.
