WG3021 1X4 Desktop Mechanical Optical Switch -SM 1280-1610nm / MM 850nm, Low Insertion Loss 1.5dB, 60dB Crosstalk, 20ms Switching, RS232/USB, for Optical Module Testing & Fiber Network Routing

The WG3021 is a 1X4 desktop mechanical optical switch engineered for automated optical path routing in component testing, transceiver module characterization, and fiber network verification. Its mechanical switching architecture delivers 1.5dB insertion loss, 60dB crosstalk suppression, 45dB return loss, and 0.05dB insertion-loss uniformity across channels-metrics that preserve signal integrity in loss-budget-sensitive test chains. 20ms switching time and 10⁷ (ten million) switching cycles support high-duty-cycle automated test environments without relay degradation. Operating across SM 1280–1610nm or MM 850nm, with 0.15dB polarization-dependent loss and 0.4dB wavelength-dependent loss, the WG3021 suits both single-mode and multimode routing scenarios. 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 keys and LED indicators support standalone operation. Its compact 205×205×100mm / ≤1kg chassis and AC 100–250V input suit lab benches and production floors alike. The WG3021 is purpose-built for optical device inspection, transceiver module tuning, fiber network testing, and automated test system integration—wherever a 1×4 path selector must be reliable, repeatable, and script-controllable.
