LEAP OBT 12-TRX 192G NRZ - RUGGED
Contact:
The LEAP® On-Board Transceiver is a rugged 12-channel duplex optical transceiver capable of running data-rates of up to 16Gbps per channel (192Gbps cumulative) on multi-mode fiber:
- Operating case temperature: (-40°C;+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 has first been introduced by AAOP in its commercial version (12TRx; 25Gbps per channel; 300Gbps aggregate in each direction) in 2015 to serve the needs for high-density and high-data rate applications in datacenters, supercomputers and 5G broadband infrastructures.
AAOP added the rugged version of its LEAP OBT to its portfolio in 2020.
The LEAP OBT is connected to the PCB using a dedicated BGA socket and four screws. The optical interface fits a MT24 ferule which is fixed onto the module by means of a clip.
- Small footprint (1inchx1inch) allows for an optimal space-saving solution
- Data rate transparent from 300Mbps to 16 Gbps*
- Fiber connection via standard MT24 ferrule – Separable Interface
- Two-wire control and diagnostic interface (i²c)
- Temperature monitoring
- Input voltage (module)
- Rx Power monitoring (RSSI)
- Programmable input equalization
- Programmable output amplitude and de-emphasis
- Low power consumption (0.3W average per channel at 10Gbps Tx+Rx)
- High optical link-budget (14dB nominal at 10 Gbps, PRBS31)
*Amphenol can provide the fiber optic cables on request (e.g. MT-MPO or MT-fanouts)
