A:
Yes, keeping the fiber tips clean is always a good idea. Even tiny dust specks on the LC connector can cause signal dropouts and optical reflections. Using a standard 1.25mm one-click LC cleaner before plugging it in will give you a clean, reliable link. By

A:
Yes, two C34 DWDM modules may be connected directly over a duplex single-mode fiber pair when the link carries only that point-to-point connection. Check that the total fiber and connector loss fits the optical budget, and verify that the received power remains within the module's specified Rx range after installation. By

Deployed a batch of these LS-DW3410-40C transceiver modules for an enterprise campus network expansion. Both links span roughly 32km of SMF through patch panels. The PIN receiver sensitivity held up with 4dB margin to spare, and the operating temperature stays around 38°C in a ventilated rack. Excellent performance for the price.
