De-Tech AOP800A TO Type 1.25 Gbps APD Receiver Optical Subassembly

DESCRIPTION
This receiver optical subassembly (ROSA) is designed for fiber optic transmission system up to 2.5 Gb/s including PON, SDH/SONET, Gigabit Ethernet and Fiber Channel etc. It consists of a high-performance InGaAs/InP APD and a low-noise transimpedance preamplifier. The chips are hermetically sealed in a 5-pin TO-46 package.

FEATURES

  • Data rate up to 2.5 Gb/s
  • High performance InGaAs/InP APD
  • High sensitivity
  • 5-pin TO-46 with ball lens

APPLICATIONS

  • PON
  • SDH/SONET
  • Gigabit Ethernet
  • Fiber Channel
  • Other long-haul transmission system up to 2.5 Gb/s
