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: [email protected][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.

Features & Benefits:

  • Small Cubic Form Factor (SCFF) -> half the area of an SFP+
  • Data rate transparent from 1.25Gbps to 28.05Gbps*
  • Duplex LC optical interface (ARINC801 adapter option)
  • SFF-8472 compliant 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 (<0.45W at 10Gbps [0°;+85°C] Tx+Rx)
  • High link-budget (14dB nominal at 10 Gbps)

* for 25Gbps version only
