Two fiber-to-the-premises (FTTP) vendors chipped in Monday with platforms that use two different technologies.

BroadLight Inc. unveiled a GPON-based silicon system, while Siemens Communications went with more traditional BPON technology.

For its part, BroadLight introduced a GPON system featuring the BL2000, a BPON System-on-Chip for ONT (optical network terminal) equipment. The full system, which will sell for less than $20 in high volumes, also is comprised of the company's PONmaker software, OLT MAC, and OLT (optical line terminal) and ONT transceivers. The company said the system is designed to pump out 2.5 Gbps of packet and 155 Mbps of TDM data for up to 64 users on a single PON.

Siemens, meanwhile, introduced a portfolio based on BPON, including ONTs and ONUs (optical network units). The system touts throughput up to 100 Mbps on an Ethernet port, and up to 622 Mbps over a full service access network (FSAN)-compatible fiber connection.

Siemens also announced a successful interop of its BPON family with the Calix C7 access platform.
