CWDM Tx/1550nmRx RFOG Bi-Directional Optical Subassembly
Description
LBxx12 series has a CWDM(TX)/1550nm(RX)
Bi-direction Optical Sub-assembly (BOSA) for analog transmission application .
This module contains a O&E band(1260~1460nm) MQW CWDM laser diode as transmitter, the wavelength of CWDM will be selected, an InGaAs/ InP PIN as receiver,
an edge filter (CWDM transmit / 1550nm reflect) to separate original band and 1550nm laser.
The TX with an InGaAs monitor PD, it can be used
with appropriate feedback control circuitry to set optimal
power level for each CWDM DFB 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 PIN chip has a photosensitivity
area diameter of 80um with a InGaAs planar structure.
The products has single mode type fiber(G.657A) with
a FC/APC or SC/APC optical connector can be selected
