The WG3067 is a dual 1×4 desktop mechanical optical switch that integrates two independent 1×4 mechanical switch elements and their control circuitry into a single benchtop unit, enabling simultaneous, parallel routing of two fiber paths across four output channels each. Rather than cascading or stacking two separate 1×4 switches, the WG3067 gives production engineers and lab integrators a compact, single-chassis solution for test setups that require two synchronized 1×4 path selectors—such as dual-lane optical module testing, paired device characterization, and redundant fiber link switching. Front-panel keys and LED indicators provide standalone operation, while USB and LAN interfaces enable full remote control for integration into automated test sequences alongside power meters, attenuators, and source-measure units. The mechanical switching design prioritizes low insertion loss and high repeatability over MEMS-level switching speed, making it suited to applications where routing reliability and signal integrity matter more than microsecond response. Its compact benchtop form factor suits lab benches, production floors, and system integration where two 1×4 paths must be switched in lockstep. The WG3067 is purpose-built for optical module production testing, passive component inspection, fiber sensing network routing, and LiDAR multi-channel optical path management.
