Fiber Box

A: A fiber optic termination box (FTB) is a compact unit that terminates the end of an optical cable and provides connection points (via adapters and pigtails) for one or more subscriber drops. It typically handles 2–48 fibers and is installed at the building or subscriber level. A fiber distribution box (FDB or ODB) is a larger, more complex enclosure that not only terminates the incoming feeder cable but also integrates a PLC splitter to distribute the optical signal to multiple subscribers. Distribution boxes in FTTx networks serve as the second-stage splitting point — connecting feeder cables from the primary equipment room to individual drop cables for 8, 16, or 32 subscribers simultaneously.

A: For pole-mounted or wall-mounted outdoor applications exposed to rain and dust, a minimum IP65 rating is recommended. IP65 ensures complete dust protection and resistance to low-pressure water jets from any direction. For underground installations (conduit, manholes, direct burial), IP68 is required — this rating certifies the enclosure can withstand continuous submersion in water up to 1 meter deep for 30 minutes or more. Our dome-type and inline splice closures are IP68-certified with additional IK09 mechanical impact protection. We do not recommend using IP54-rated units for fully exposed outdoor environments where standing water is possible.

A: The correct port count depends on your network topology and subscriber density. For a typical single-family FTTH drop, a 2-port or 4-port termination box is sufficient. For apartment buildings, a 12–48 port distribution box per floor or per building block is common. For GPON networks using 1:16 or 1:32 splitting ratios, you'll need a distribution box that can accommodate 16 or 32 drop connections plus the splitter module. Our engineering team is available to help size your project correctly — provide us with the number of subscribers, network architecture (GPON/EPON/P2P), and installation environment, and we'll recommend the right products.

A: Yes. OEM and ODM manufacturing is a core part of our business. We can produce fiber boxes with your company logo, custom colors, custom labeling, and tailored port configurations. Custom mold development is available for unique enclosure shapes or sizes. Our minimum order quantity for standard OEM (logo + color only) is typically 100–500 units per SKU. For new mold development, please contact us to discuss tooling costs and timelines. Sample approval is required before mass production. Lead time for OEM mass production orders is typically 15–25 working days after sample approval.

A: Our fiber boxes are compatible with all standard fiber optic connector types: SC (Subscriber Connector), LC (Lucent Connector), FC (Ferrule Connector), and ST (Straight Tip). Both simplex and duplex adapter formats are available, and polishing options include UPC (Ultra Physical Contact) and APC (Angled Physical Contact). SC/APC is the most common interface for FTTH access networks in Europe and Latin America, while LC/UPC is popular in high-density data center environments. We can configure any adapter type into our termination boxes or distribution boxes — just specify your requirements at the time of inquiry.

A: A NAP (Network Access Point) box — also referred to as a CTO (Customer Termination Outlet) or FAT (Fiber Access Terminal) box — is a specialized outdoor distribution box used in FTTH/GPON networks as a pre-connectorized, street-level distribution point. Unlike a basic termination box that simply provides a patching interface, a NAP box integrates fiber splicing, PLC splitting, and drop cable distribution in a single compact enclosure that is pre-loaded with connectors and pigtails at the factory. This allows field technicians to activate new subscribers simply by plugging in a pre-made drop cable — no fusion splicing in the field is required, significantly reducing deployment time and cost.

A: Yes. We provide free product samples for evaluation purposes. Standard catalog samples are available at no charge — you are responsible only for the shipping cost. For customized OEM samples, a nominal tooling or engineering fee may apply depending on the complexity of the customization. Sample delivery time is typically 3–7 business days for standard products. Please submit a sample request through our inquiry form or contact us via WhatsApp, and our sales team will arrange dispatch within 24 hours of confirmation.

A: For standard catalog products, our MOQ starts at 50–100 pieces per model, and many items are held in stock for immediate shipment. For custom OEM products, MOQs typically start at 200–500 units. Production lead time for standard in-stock items is 3–7 days. For made-to-order products, lead time is 10–20 working days depending on complexity and order volume. We ship via DHL, FedEx, UPS, and sea freight (LCL/FCL). Dedicated account managers handle all export documentation, including commercial invoices, packing lists, certificates of origin, and CE/RoHS compliance documents.
