The SX4 is an optical subassembly (OSA) that provides four 3.5 Gbps video or data Tx or Rx lanes all multiplexed onto just a single multimode fiber. The Tx OSA includes a four-channel laser diode driver (LDD) with pre-programmed laser settings for optimal link performance over the full temperature range. The Rx OSA includes an integrated transimpedance and limiting amplifier (TIA) to provide a robust output with excellent optical input sensitivity. The OSAs 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.
