Fiber termination boxes and fiber distribution boxes
A fiber termination box is where a fiber cable ends: its fibers are spliced to pigtails, or arrive pre-connectorised, and meet adapters on a panel, so patch cords or drop cables can plug in. A fiber distribution box adds a PLC splitter and serves several homes from one feeder fiber. ZeroLine Connect supplies both, from 1-port wall outlets to outdoor IP65 boxes and 19-inch rack shelves, loaded with adapters, pigtails and splitters to your design.

Typical values from Optics Valley makers’ catalogues. Your offer states the box supplied, and the maker’s datasheet ships with the order.
| Part | What it does | Typical place |
|---|---|---|
| Termination box | Ends a cable on adapters for patching | Home, building, rack |
| Distribution box (FAT, FDB) | Splits one feeder fiber and serves drops | Pole, wall, basement |
| Splice closure | Joins cables in a sealed housing; no patching | Manholes, poles, aerial spans |

| Item | Why it matters |
|---|---|
| Ports and adapter type | Homes or links served plus spare ports; SC/APC, SC/UPC or LC |
| Splitter ratio and package | Must match your split design and fit the box |
| Cable entries and diameters | The feeder and drop cables must enter sealed |
| Pre-loading | Pigtails spliced or not, splitter fitted, hardened adapters for pre-connectorised drops |
| Indoor or outdoor rating | IP65 and UV resistance outdoors |
| Labels and packing | Port labels to your scheme, boxes packed per street |

Terms
Ordering, testing and delivery
Typical terms. Your offer states the exact terms for your order.
- Minimum order
-
One drum of cable, one reel of fiber or one carton of passive components. Mixed BOMs are welcome. Samples for evaluation typically ship in 1–3 weeks.
- Lead time
-
Stock items 5–10 working days. Made-to-order cable typically 2–4 weeks. Large framework lots ship on the agreed rollout schedule. Fiber prices moved sharply in 2026, so every cable offer states how long its price holds next to the lead time.
Fiber and cable prices in 2026 - Test reports
-
OTDR data for every drum of cable, insertion and return loss for every connectorised assembly, loss and uniformity reports for splitters, and our pre-shipment inspection report. Third-party pre-shipment inspection on request, at the buyer’s cost.
- Labelling and packing
-
Drum and carton labels to your scheme: project, lot, route or rack. Export cartons, and wooden or plywood drums for cable.
- Payment
-
T/T with 30% deposit and 70% before shipment, or L/C at sight. Rollouts can run under a framework agreement with staged lots.
Payment terms and trade finance - Delivery
-
FOB Wuhan or Shanghai, CIF to your port, or door delivery where available. Goods from other ZeroLine lines ship in the same consignment when that saves freight.

FAQ
Fiber termination boxes: questions buyers ask
What is a fiber termination box?
It is the box where a fiber cable ends. Each fiber is spliced to a pigtail, or arrives with a connector, and plugs into an adapter on the box’s panel, so patch cords or drop cables can connect. A splice tray inside protects the joints and the spare fiber.
What is the difference between a termination box and a distribution box?
A termination box ends a cable on adapters. A distribution box also holds a PLC splitter, so one feeder fiber serves 8, 16 or 24 drop cables; FTTH networks place them on poles or walls near the homes they serve and call them FAT or NAP boxes.
How many ports do I need?
Count the homes or links the box will serve and add spare ports for growth, commonly 10–20%. In PON networks the port count usually matches the splitter: a 1×16 splitter for a 16-port box.
Indoor or outdoor box?
Outdoor boxes are sealed to IP65 and made of UV-stabilised plastic for poles and walls. Indoor boxes are lighter and cheaper and suit risers, basements and homes. Rack-mount boxes go into 19-inch racks.
