LEAP® ON-BOARD TRANSCEIVER 

12-TRX 300Gb/s High-Speed Optical Module

The LEAP® On-Board Transceiver is a rugged 12-channel duplex optical transceiver capable of achieving data rates of up to 28.05Gbps per channel, up to 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 to 85°C
  • 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 24F MT ferrule, securely attached to the module using a clip mechanism.

The LEAP® 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 5.4W of power.  

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

Features & Benefits:

  • Small footprint (1"x1") allows for an optimal space-saving solution
  • Data rate transparent from 300Mbps to 25.08Gbps*
  • Accepts standard MT24 ferrule – Separable Interface
  • Two-wire control and diagnostic interface (I²C)
    • Tx Power monitoring
    • Temperature monitoring
    • Input voltage (module)
    • Rx Power monitoring (RSSI)
    • Bias current monitoring
    • Programmable input equalization
    • Programmable output amplitude and de-emphasis
  • Clock and Data Recovery functionality
  • Low power consumption (0.3W average per channel at 10Gbps Tx+Rx)
  • High link-budget (14dB nominal at 10Gbps, PRBS31)

*Amphenol can provide the fiber optic cables on request (e.g. MT-MPO or MT-fanouts)

VITA compliant: 66.1, 66.2, 66.4, 66.5, 67

Usable in SOSA-aligned systems
