The WG3025 is a 1×16 desktop mechanical optical switch engineered for automated optical path routing in optical module mass production testing, device inspection, and fiber network verification. It routes one input fiber across sixteen output channels from a single benchtop chassis, replacing cascaded lower-channel-count switches and the cumulative insertion loss they introduce. The mechanical switching architecture delivers low insertion loss and low crosstalk with high repeatability, preserving signal integrity across repeated test cycles. Operating across single-mode 1270–1650nm or multimode 850nm, the WG3025 suits both SM and MM routing scenarios. 10⁷ (ten million) switching cycles support high-duty-cycle automated production environments. RS232 and USB interfaces enable full remote control, allowing the switch to be sequenced alongside power meters, attenuators, and source-measure units in a single automated test script; front-panel buttons and LED indicators support standalone operation. Its 450×300×88mm chassis and AC 100–250V input suit lab benches and production floors alike. The WG3025 is purpose-built for optical module production testing, optical device mass production inspection, fiber network testing, and automated test system integration—wherever a 1×16 path selector must be reliable, repeatable, and script-controllable.
