Dual-feed protection splitting for ring PON. Factory-terminated and 100% tested before shipment.
Two upstream feeds, redundant paths: 2×N PLC splitters enable Type-B PON protection and ring architectures where a second OLT feed takes over on fiber cuts — same flat PLC performance, dual-input chip.
High-return-loss APC terminations standard; all ports individually verified.

With inputs fed from two OLT ports (or two routes), downstream users survive a single upstream fiber cut — the second feed carries traffic after OLT-side switchover.
Every assembly undergoes 100% optical inspection plus insertion- and return-loss testing to IEC, TIA/EIA and Telcordia standards. Test reports are available on request.
Yes — length, jacket color and material (PVC / LSZH / OFNP / OFNR), cable diameter (0.9 / 2.0 / 3.0 mm) and any connector combination are OEM/ODM customizable.
Standard configurations ship in 3–7 days with flexible MOQ. Custom OEM/ODM runs are quoted per project — send us your specs for a fast quotation.
Tell us the platform and the quantity. An engineer checks the part against your switch and software version before quoting — if it will not work, we say so.
