The Leap On-Board-Transceiver (OBT) is a one inch square board mounted optical module which has been introduced by FCI. The device includes 12-transmit and 12-receive channels, each working at 25Gb/s over distances up to 100m with a total of 300Gb/s throughput. When placed near the host ASIC, the LEAP enables shorter copper board traces, better signal integrity and lower power consumption.
Optical connectivity is achieved via a high-density ribbon fibre assembly connecting to the front panel with an optical connector system such as the MPO or MXC connector and adapter. A standard MT ferrule is used on the transceiver side, while the transceiver is connected to the board with an FCI proprietary surface mount electrical BGA/LGA socket.
Optimised for low power consumption, the OBT features a total typical power consumption of only 2.7 without and 5.4W with CDR. The device has been engineered with the latest 850nm VCSEL and PIN array technology operating at 25Gb/s along with the latest 25Gb/s laser driver and TIA chip set.
Roy Muscarella, Vice President and General Manager, High Speed Input/Output Solutions Group, FCI, commented: “FCI’s Leap OBT design addresses a number of emerging industry trends and hardware designer needs. These trends and needs, such as increased I/O port density, minimised 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.”
Evaluation kits are available upon request. The product is scheduled to be available in the second half of 2015.
