Terawave and K-micro Partner on GPON PHY

Terawave Communications and K-micro (Kawasaki Microelectronics) introduced a jointly developed physical layer ("PHY") ASIC built specifically for gigabit passive optical networking (GPON) optical line terminals (OLTs). The companies said their ASIC enables extremely low GPON physical layer overhead by providing fast phase locking to incoming bursts along with the associated hardware hooks to synchronize upstream traffic within a few bits at 1244 Mbps.

K-micro has integrated its burst mode clock and data recovery (BM-CDR) technology into this new ASIC. It has appeared in two previous generations: the first-generation "Copper Tub" (CT1) that runs at 1244/1244, and a later CT2 that runs at 2488/1244.

The Terawave TW-800 Family of OLTs are the first products to incorporate this technology. The TW-801 OLT is one of a series of OLT packages designed to address the emerging GPON global market. These products are completely G.984.x ITU standards compliant.
