Glasgow’s CST samples lasers for 10G optical networks

CST Global, the Glasgow semiconductor laser manufacturer, says it is sampling its 1270nm, 2.5Gbit/s asymmetric and 10Gbit/s symmetric, DFB lasers for 10G PON (passive optical network) applications.

The firm is currently beta sampling its asymmetric 2.5Gbit/s lasers and alpha sampling its symmetric, 10Gbit/s lasers.

The asymmetric beta samples, which are undergoing ITU-GR468 reliability testing, are available for customer trials in Known Good Die on Tape (KGDT) and TO 56 Can formats.

Andrew McKee, Technical Director at CST Global, writes:

“The asymmetric, 2.5Gbit/s, 1270nm DFB lasers allow the existing optical networking units found at the user end of fibre-to-the-home broadband solutions, to be re-used.”

To design in the  symmetric, 10Gbit/s, 1270nm laser option will require a new design of the optical networking unit before a large-scale uptake is expected.

“But it is already in demand. These are the two, prevailing technologies in this growing market,” said McKee.

CST Global will exhibit at the OFC (Optical Networking and Communication) Conference and Exhibition in San Diego, 11-15th March.
