IQOTX80-83

3G/HD/SD-SDI Multi-Channel Fiber Transmitter

The IQOTX80-83 range converts eight 3G/HD/SD-SDI signals into single-mode fiber optic signals. The unit is available in single- or dual-width versions with either HD-BNC or BNC connectors with a range of fiber wavelength transmitters suitable for CWDM applications.

FEATURES

  • Multichannel single-mode fiber optic transmitter for 3G/HD/SD-SDI signals
  • Output wavelengths from 1270 nm to 1610 nm suitable for CWDM applications
  • Reclocking for 3 Gb/s, 1.5 Gb/s HD-SDI and 270 Mb/s SDI signals, or asynchronous operation for other frequencies (input range 50 Mb/s to 3 Gb/s)
