These RX77R1A 2.5 Gbps fiber optic receivers are designed for use in telecommunication
and high-speed data communication applications. The receivers operate at SONET OC-48 and
SDH STM-16 data rate. The receivers convert received optical signals in the range of 1200 nm to
1600 nm wavelength into single-ended data and differential clock outputs. The receivers consist
of either InGaAs APD or PIN photodiode, a GaAs transimpedance amplifier, and a clock and data
recovery (CDR) IC.
Key Features
• Optimized for SONET OC-48 and SDH STM-16 data rate
• Operation from 1200 nm to 1600 nm
• APD and PIN versions available
• Typical sensitivity : -32 dBm with APD
-24 dBm with PIN
• Operating case temperature range
- APD : 0 °C to 65 °C
- PIN : 0 °C to 65 °C
• SC or FC/PC connector
Applications
• Telecommunication
- SONET/SDH
- Metropolitan area networks
- Wide area networks
• High speed data communications
