SX4 Optical Subsystem

The SX4 is an optical subsystem that provides 14 Gbps (4 x 3.5 Gbps) video or data Tx or Rx lanes all multiplexed onto just one multimode fiber. The Tx subsystem includes a four-channel laser diode driver (LDD) with pre-programmed laser settings for optimal link performance over the full temperature range. The Rx subsystem includes an integrated transimpedance and limiting amplifier (TIA) to provide a robust output with excellent optical input sensitivity. The subsystems feature a ZIF-terminated flex circuit and optical SC fiber interface for easy assembly and manufacturing test. Let Inneos handle the optoelectronics so you can focus on the performance of your high-speed data link.
