Future Optics‘ 4 CH LWDM R-B 1100 Mux Block is a LWDM EML Tx Block to act as a Mux optical sub-assembly for Tosa module, working at red-band from 1295.56 to 1309.14 nm and matching with 1.1 mm pitch LD or LD array, which is integrated inside the transmitting end of transceivers to combine 800GHz spacing 4 channels from lasers. This device adopts TFF technology and Free-Space technology, inside the device adjacent signal channels are cascaded by parallel beam with the zerodur based filters, thus the reliability is significantly improved, offering high precision of beam parallel and wider operation temperature range.
