1310nmTx/1550nmRx FP Bi-Directional Optical Subassembly
LB3F12 series is a 1310(TX)/1550nm(RX) Bi-direction Optical Subassembly (BOSA) for RFOG transmission application .
This module contains a 1310nm MQW FP laser diode as transmitter, an InGaAs/InP PIN as receiver, an edge filter (1310nm transmit / 1550nm reflect) to separate 1310nm and 1550nm wavelength.
The FP with an InGaAs monitor PD, it can be used with appropriate feedback control circuitry to set optical power of the FP laser, As the current changed above the threshold, the optical power will change accordingly.
The PD transduces incident light into optical current with high efficiency. The PD chip has a photosensitivity area diameter of 80um with a InGaAs planar structure.
The product has single mode type fiber with a FC/APC or SC/APC optical connector.
