Engineered for demanding field and industrial environments, the unit provides feed‑through connection with an automatic sealing shutter and can achieve an IP65 waterproof rating when mated with the SO2M plug. Key Features • Dual‑channel, feed‑through coupler for LC‑Duplex single‑mode connections • Compatible with conventional single‑mode LC connectors • Automatic sealing shutter for protection of unused ports • Achieves IP65 waterproof grade when used with SO2M plug • Push‑pull locking for quick, secure mating Packaging & Accessories • Packed with pearl cotton protective packaging; one product per small box • Standard delivery: no accessories included (optional accessories such as back fastener plate, screws & nuts listed as available but not supplied) Installation / Usage Notes Remove the stainless‑steel dust cover, insert an SO2M connector into one side of the SO2DFF‑S, then repeat on the opposite side to complete the fiber cable connection. The automatic sealing shutter protects unused ports during installation. The SO2DFF‑S is a compact, durable LC‑Duplex fiber coupler optimized for single‑mode applications where low insertion loss, environmental protection (IP65 with SO2M), and reliable mechanical performance (push‑pull locking, >1,000 mating cycles) are required.
