Fiber Distribution Box Manufacturer

Fibconet valmistaa 12 series of outdoor fiber distribution boxes for FTTH last-mile deployment. In the industry these are also called RASVA (Kuitupääte), FDB, tai kuitupäätelaatikko. Two families cover the two roles in a PON tree — Subscriber Boxes lopettaa 4 kohtaan 24 drop-cable ports at pole, wall or building entry, ja Hub Boxes concentrate 1×8 or 1×16 splitting upstream of the subscriber layer.

Housings are ultrasonic-welded PC alloy or PC+ABS with V0 flame rating, qualified to IK09 impact and IP66 or IP68 sealing. Our factory keeps a rolling stock of 1,000 pcs on regular models, ships bulk orders under 5,000 pcs in about 15 päivää, and supports OEM color, logo, port layout and CAD drawings from an MOQ of 1,000 kpl. Products currently ship into ISP and EPC contractor projects in Brazil, Chile, Indonesia and Malaysia.

The sections below list the 12 models grouped by role, then cover the Sub-vs-Hub selection logic, tekniset parametrit, manufacturing capability, packaging and OEM options, FAQ, and a quotation channel.

12 Distribution Box Models We Manufacture

ryhmä 1 — Subscriber Boxes (end-user drop termination, 4 kohtaan 24 portit)

What Is a FAT Box and How to Choose the Right Type

Sub Box vs Hub Box — Two Layers of the FTTH Access Network

A PON access network has two enclosures between the OLT and the subscriber. Confusing them is the single most common cause of over- or under-buying.

	Hub Box (upper layer)	Subscriber Box (lower layer)
Position	Between feeder cable and drop cables	At the drop point closest to homes
Contains	PLC-jakaja(s), liitosalusta, sovittimet	Sovittimet, sometimes a small splitter, liitosalusta
Kapasiteetti	1×8 or 1×16 splitting, aikeissa 32 drops downstream	4, 8, 16, 18 tai 24 subscriber ports
Typical sealing	IP66 (splash + tropical rain)	IP65 to IP68 (per exposure level)
Cable in	Feeder 5–6 mm round outdoor cable	2×3 or 2×5 drop wire, 5 mm pyöreä kaapeli
Deployment ratio	1 hub per 8–16 subscriber boxes	1 sub box per building or per pole

How to Match the Box to Your Field Scenario

• Coastal or tropical deployment → choose a PC+ABS anti-UV model with IP66 or IP68 sealing and 304 stainless-steel latch hardware for salt-spray tolerance.
• Direct-buried or pole junctions exposed to standing water → specify IP68 with ultrasonic-welded housing rather than screw-sealed IP65.
• Fast last-mile drop → choose a pre-connectorized model so the field crew clicks the drop cable in without on-site splicing.
• High-density MDU risers → use the 18 or 24-port model to reduce the number of enclosures per floor.
• PON hub upstream of subscriber layer → use a Hub Box with 1×8 or 1×16 PLC splitter capacity, not a subscriber box with an added splitter.

Valmistuskyky ja laadunvalvonta

Production History and Supply Chain

Fibconet’s parent operation in optical passive components dates back to 1994. FAT box production runs on dedicated injection molding and ultrasonic welding lines; housings are molded in-house from qualified PC and PC+ABS resins so batch-to-batch dimensional consistency stays under control. UV stabiliser and weathering-modifier additive packages are dosed to the resin at the pre-mix stage — that is what supports the 15-year outdoor field life claim.

Laadunvalvonta

• 100% pre-shipment inspection of every box before packing.
• Sealing test on the finished enclosure — waterproof and dustproof per rated IP grade.
• Impact test to IK09 on housing samples per batch.
• Thermal cycle and humidity test at high and low temperature per model qualification.
• Full-load distribution test with splitter and adapter fitted, to confirm cable-management fit under real port load.
• Field defect rate: overall factory defect rate below 0.5%; post-delivery rework rate below 0.2% (figure includes damage from on-site handling, so the true product-only rework rate is lower).

Sertifikaatit ja vaatimustenmukaisuus

Raw material RoHS reports are supplied by default with every shipment. Fibconet operates under an ISO 9001 quality management system. Additional certifications — REACH, TÄMÄ, UL94 V0 for the resin, third-party IP grade test reports — are issued per model and per project requirement. Send us your target market and the model list; we return the applicable certificate set with the quotation.

Usein kysytyt kysymykset

Q1. What is the difference between a Sub Box and a Hub Box?

The Hub Box sits upstream, holds the 1×8 or 1×16 PLC splitter and feeds several downstream Subscriber Boxes. The Subscriber Box sits at the drop point closest to homes and terminates 4 kohtaan 24 pudota kaapeleita. A typical PON tree runs one Hub Box per 8–16 Subscriber Boxes.

Q2. What sealing grade should I specify for a tropical coastal deployment?

Ask for IP68 with ultrasonic welding for splash-heavy or immersion-prone junctions, and PC+ABS alloy with UV additive package plus 304 stainless-steel latch hardware for salt-spray tolerance. Screw-sealed IP65 boxes are fine indoors but not on coastal poles.

Q3. Which connector housings are compatible with your adapter panels?

Panels are drilled and tooled to the mainstream footprints — Huawei, Corning and Fiberhome. Send us your target adapter model at RFQ stage; if it is a proprietary housing we confirm feasibility before quoting.

Q4. What is the MOQ and what happens if I need a small trial batch first?

MOQ for custom configuration is 1,000 kpl. For a trial or sample run, we can pull from the rolling 1,000-piece stock of regular models and ship smaller quantities. Ask us about sample delivery when you send the RFQ.

Q5. What is the typical lead time?

Standard-configuration orders under 5,000 pcs ship in about 15 päivää; there is no difference between peak and off-peak seasons. Custom color, logo or port layout adds about 10–14 days. Confirm the actual date on the pro-forma invoice.

Q6. Can you supply CAD drawings and an installation manual for our project design review?

Joo. After order confirmation, we send CAD drawings and an installation manual per model. A short installation video is also available for wall-mount and pole-mount configurations.

Q7. What outdoor field life do these boxes hold?

Modified PC+ABS alloy with a UV stabiliser and weathering-modifier additive package supports about 15 years of outdoor service without cracking, weathering or powdering, within the −40°C to +65°C operating range.

Q8. Do you handle later capacity expansion, such as adding ports or changing the splitting ratio?

Existing models are not field-expandable. If your project needs an expandable design, we can develop a custom housing from your specification; the development plus tooling cycle is quoted separately.

Q9. Do you provide RoHS and third-party test reports?

Raw material RoHS reports are supplied by default. REACH, TÄMÄ, UL94 V0 resin certification and third-party IP grade test reports are provided on request; if you need a certificate we do not yet hold, voimme järjestää kolmannen osapuolen testauksen projektin mittakaavassa.

Q10. What is your factory defect rate and post-delivery rework rate on previous batches?

Overall factory defect rate is below 0.5%. Post-delivery rework rate is below 0.2%, and that number includes damage from on-site handling — so the true product-only rework rate is lower. Batch inspection records are available on request for tender projects.
