1550nmTx/1310nmRx FP Bi-Directional Optical Subassembly
Description
LB5F11 series is a 1550(TX)/1310nm(RX) Bi-direction Optical Subassembly (BOSA) for RFOG transmission application .
This module contains a 1550nm MQW FP laser diode as transmitter, an InGaAs/InP PIN as receiver, an edge filter (1550nm transmit / 1310nm reflect) to separate 1310nm and 1550nm wavelength.
The FP laser integrated an InGaAs monitor PD, it can be used with appropriate feedback control circuitry to set optical power level of the FP laser, As the current changed above the threshold, the optical power will change accordingly.
The PIN transduces incident light into optical current with high efficiency. The photosensitivity area of the PIN chip is 80um with a InGaAs planar structure.
This product has a single mode type fiber with a FC/APC or SC/APC optical connector.
