We report four-wave mixing mitigation by 4λ-WDM filters fabricated by silica-based planar lightwave circuits for 800- and 400-GbE application. The multiplexing filter integrates a simple polarization-alternating structure on arbitrary lanes for the

An AXEL sub-assembly and a 4-channel AXEL TOSA were designed and fabricated. The sub-assembly with a width of less than 0.65 mm was needed to make the width of TOSA applicable to QSFP-DD transceiver. On the other hand, the wire that connects between
