SCFF Rugged Optical Transceiver (1TRx)
Contact:
Description:
The rugged SCFF ("Small Cubical Form Factor) is a 1-channel duplex multi-mode (850nm) on-board transceiver with a 12pin electrical interface (SMT) complying specification SFF-8431 for high speed interfaces.
It operates at data-rates up to 25Gbps in harsh environment:
- 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 SCFF series has first been introducted in 2009 for 10Gbps speeds. A new rugged version of the SCFF has been developed by AAOP in 2019 to answer the needs for increased data-rates (25Gbps) and harsh-environment applications. The rugged SCFF is a “chip-on-board” transceiver leveraging state of the art 25Gbps chipsets from the data-com industry (VCSEL drivers, TIA, VCSEL, PIN Diodes).
The rugged SCFF is mounted on a PCB using two screws and is solder-mount on the rear connector. Its height has been optimized to be lower than 10mm above the PCB to fit the state-of-the art electronic casings.
