LEAP

The LEAP® OBT (On-Board Transceiver) is a rugged 12-channel full-duplex optical transceiver capable of achieving data rates of up to 28.05Gbps per channel, or 300Gbps in total when considering all channels. This high-speed fiber optic transceiver is optimized for multi-mode fiber at 850nm and operates effectively in a wide range of conditions:

• Operating temperatures from -40°C (-40°F) to 85°C (185ºF)
• Shock: (500g; 1ms) per MIL STD-883 Method 2002.4
• Vibration: (20g, 20-2000Hz) per MIL STD-883 Method 2007.3

The LEAP® On-Board Transceiver was initially introduced in its commercial version (known as 12TRx) in 2015 by Amphenol (formally FCi). It is designed to cater to the demands of high-density and high-data-rate applications commonly found in datacenters, supercomputers, and 5G broadband infrastructures.

Amphenol expanded its offerings in 2020 by ruggedizing the LEAP® OBT. This rugged variant provides enhanced durability and reliability while maintaining speed and density.

To connect the LEAP® OBT to a PCB, a dedicated BGA socket and four screws are used. The optical interface features a 24F MT ferrule, securely attached to the module using a clip mechanism. Importantly, this optical interface is removable for manufacturability, and flexibility in design.

The LEAP® OBT is faster, smaller, more cost and power-efficient than any conventional card-edge datacenter interconnects and is capable of speeds of up to 25Gbps with 300Gbps of total throughput that requires only one square-inch of board space and 5.8W of power. 

The LEAP® OBT adheres to VITA standards: 66.1, 66.2, 66.4, 66.5, 67 and is compatible with SOSA-aligned systems.
