Fibre FAT Box – 1×16 Bare PLC Splitter
\
This outdoor-rated Fiber Access Termination (FAT) box seamlessly integrates a 1×16 bare PLC splitter with splicing and distribution functionality in a compact, weatherproof enclosure. Engineered for FTTx deployments (FTTH, FTTB, PON), it efficiently distributes a single feeder fiber into up to 16 subscriber drop lines via SC adapter ports.
🛠️ Key Features
-
1×16 bare PLC splitter (unconnectorized steel-tube or ABS module type); designed for insertion into FAT trays or cassettes—offers consistent splitting efficiency with low loss
-
Low insertion loss: typically ≤ 12 dB, max ≤ 13 dB; uniformity ≤ 1.5 dB, return/directivity ≥ 50–55 dB, PDL ≤ 0.2–0.3 dB
-
Wide operating wavelength: 1260–1650 nm supports GPON, LAN/WAN, CATV
-
Rugged outdoor enclosure made of PC+ABS (or high-impact plastic), offering IP65–IP66 protection and UV resistance—suitable for pole, wall, or aerial installation
-
Integrated splice and adapter trays: supports feeder-to-splitter mechanical or fusion splicing, plus up to 16 SC adapter ports for drop fibers
-
Cable routing & bend-radius control: ensures minimum bend radius (≥ 40 mm) and clean cable organization for multiple feeder inlets and drop outlets
-
Compact & lightweight: typical dimensions around 320 × 240 × 100 mm, weight approx. 1.5 kg
