FCI’s New 25Gb/s Optical On-Board Transceiver

FCI’s new 25Gb/s optical on-board transceiver, just one square inch in size, features 12 transmit and 12 receive channels.

FCIFCI Leap On-Board Transceiver has released the Leap On-board-Transceiver (OBT) system. The one-square-inch board-mounted optical module features 12 transmit and 12 receive channels, each working at 25Gb/s over distances up to 100m with a total of 300Gb/s throughput.

The OBT is designed to be placed near the host ASIC, which results in shorter copper board traces, better signal integrity, and lower power consumption. The transceiver is connected to the board via an FCI proprietary surface-mount electrical BGA/LGA socket. Optical connectivity to-and-from the OBT is realized by using a high-density ribbon fiber assembly that connects to the front panel with an optical connector system such as the MPO or MXC connector and adaptor. A standard MT ferrule is used on the transceiver side.

This next generation of product has been engineered with the latest 850nm VCSEL and PIN array technology, operating at 25Gb/s along with the latest 25G/s laser driver and TIA chip set. The design is optimized for low power consumption, which results in a typical power consumption of only 2.7W without CDR and 5.4W with CDR.

“FCI’s new Leap On-board Transceiver design addresses a number of emerging industry trends and hardware designer needs,” said Roy Muscarella, vice president and general manager of FCI’s High-Speed Input/Output Solutions Group. “These trends and needs, such as increased I/O port density; minimized PCB real estate use; lower copper trace losses on the PCB; and the need for 25Gb/s-capable channels, are all addressed in FCI’s OBT package.”

The Leap On-board Transceiver is part of a new generation of products operating at 25Gb/s per channel. Several other transceiver and active optical cable products are planned later in 2015. Evaluation kits are available upon request. The product is scheduled to be available in the second half of 2015.
