GPON ONU Triplexer Optical Subassembly with Pigtail
Description
LN0311 series has a 1310(TX)/1490nm(RX)/1550nm(RX) triplexer optical subassembly
(Tri-OSA) for GPON ONU and CATV transmission application .
This module contains a 1310nm MQW DFB laser diode as transmitter, a InGaAs/InP PIN
and a InGaAs/InP APD as receiver, two edge filter are integrated into a small housing to
separate the wavelengths 1310nm 1490nm and 1550nm.
The DFB with an InGaAs monitor PD, it can be used with appropriate feedback control
circuitry to set optimal power level for each FP laser, As the current changed above the
threshold, the optical power will change accordingly.
The PIN chip has a photosensitivity area diameter of 80um with a InGaAs planar structure,
it can be receive the optical signal and convert to analog signal.
The APD-TIA transduces incident light into optical current with high efficiency. The TIA
converts the current signal into a digital voltage signal with a very low input noise.
The products has single mode type fiber with a SC/APC optical connector can be selected.
