FTTH Optical Distribution Box

A:​ An FTTH optical distribution box (FDB), also called a fiber optic NAP box or fiber access terminal (FAT), is an outdoor or indoor enclosure that serves as the critical termination point in a passive optical network (PON). It is where the backbone feeder cable connects to individual subscriber drop cables. Inside the box, fiber splicing, PLC splitting, and distribution management all occur in one protected unit. The GL-ODB-16R is designed for FTTH, GPON, XGS-PON, and 5G fronthaul applications.

A:​ A fiber optic distribution box​ (FDB) connects one or more backbone feeder cables to multiple subscriber drop cables and typically houses a PLC splitter - it serves a group of subscribers (4–32 typical). A fiber optic termination box​ (OTB) is smaller and terminates a single drop cable at the subscriber's premises (1–4 ports typical). Distribution boxes are generally outdoor-rated (IP65–IP68) while termination boxes are often indoor-rated.

A:​ IP68 is defined by IEC 60529. The first digit "6" means the enclosure is completely dustproof - no dust ingress under any conditions. The second digit "8" means the enclosure can withstand continuous immersion in water at a defined pressure and depth (typically 1–3 meters) for 30 minutes or more without water ingress. For fiber optic distribution boxes, IP68 is the preferred rating for pole-mounted, aerial, and underground applications where sustained rain, flooding, or high-humidity exposure is expected.

A:​ The GL-ODB-16R supports three configurations via its modular splitter cassette: (A) 1×16 PLC splitter​ - one feeder input splits to all 16 output ports (highest density); (B) 2×1:8 PLC splitters​ - two independent feeder inputs, each serving 8 subscribers (network redundancy or dual-zone); (C) 4×1:4 PLC splitters​ - four independent feeder inputs, each serving 4 subscribers (fine-grained rural topology). Crucially, the splitter modules are field-replaceable, meaning your network architecture can evolve without replacing the enclosure.

A:​ FastConnect is a pre-connectorized port technology where the SC/APC or SC/UPC adapter ports are factory-terminated rather than requiring on-site fusion splicing. Instead of a splicing crew spending 45–60 minutes per subscriber connection, a single installer can plug a pre-terminated drop cable into the FastConnect port in under 5 minutes - with no OTDR verification needed for the subscriber connection. This reduces labor costs by 30–40% per distribution point deployment and allows deployment by general contractors rather than specialist fiber splicers.

A:​ Pole mounting the GL-ODB-16R: (1) Attach the stainless-steel banding straps around the pole; (2) Secure the included pole-mount bracket to the pole, maintaining safe clearance from power lines; (3) Orient the enclosure with ports facing downward to prevent rainwater pooling at connector faces; (4) Route feeder cable through the IP68-sealed cable glands at the base; (5) Route pre-terminated drop cables through the glands and plug into the FastConnect SC ports. No fusion splicer needed. Total installation time: approximately 25–30 minutes for a single installer.

A:​ Choose IP65​ for sheltered outdoor environments: building wall mount under an overhang, indoor-outdoor transition points, or climate-controlled equipment rooms. Choose IP68​ for fully exposed outdoor environments: open pole mounts, aerial installation, underground deployment, coastal/tropical climates, or any installation where flooding risk exists. For 5G fronthaul antenna mounts, choose IP68 or higher. The GL-ODB-16R is rated IP68 as standard, with an optional IP69K upgrade for high-pressure wash-down environments.

A:​ MOQ is 10 pcs for standard configurations. Sample orders (1–3 pcs) ship in 3 business days. Standard batch orders (10–500 pcs) ship in 15–20 business days. Large OEM/ODM orders with custom configuration require a 7-day engineering review + 20–35-day production lead time. All orders include full IEC test documentation and CE/RoHS compliance certificates. Contact us for volume pricing tiers starting at 100 pcs.

A:​ Yes. OEM and ODM customization options include: custom housing color (RAL standard colors available); custom laser-engraved or screen-printed logo; modified port count (4, 8, 12, or 24 ports); alternative adapter types (LC, SC, MPO on request); custom cable entry gland sizing; and custom packaging/labeling. For ODM (full custom enclosure design), minimum order is 500 pcs with a 7–10 day design review cycle. Contact our OEM team with your requirements.
