Future Optics’LWDM 4 Rx TFF integrated optical subassembly is an integrated LWDM ROSA block for 400G and beyond based on Fiber-to-the-Chip (FTTC) on-board connectivity technology, working at the Rx end of a high-speed transceiver module. It consists of receptacle, mini collimator, LWDM 4 Z-block, lens array and output prism. This integrated TFF Subassembly has lower insertion loss, high isolation and high thermal stability in comparison with LWDM Rx subassembly based on AWG technology, reducing power consumption and cost per bit by optimizing the tailored optical components and effective management of the optical system within the limited space.
