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.
