How to use

Install the coupler by inserting it into an M20 housing opening and secure it with the integrated screw connection—no tools required. Connect single-mode LC patch cables to the pre-assembled LC duplex ports, taking care to match UPC or APC polish types if applicable. Ensure the silicone seals and green sealing ring are correctly seated to maintain IP68 protection, and check that cable diameter does not exceed 2.9 mm.

Recommendations

For long-term outdoor or industrial use, verify connector end-face cleanliness before mating and avoid sharp bends at the cable entry. Use compatible single-mode LC patch cables and confirm UPC/APC polish matching to preserve optical performance.
