Fiber Optic Splice Closure Manufacturer — Dome and Inline, 12 до 840 Ядра

Виробники Fibconet 12 series of outdoor fiber optic splice closures (also called joint closures, cable closures, or in field slang dome cans) for OSP splicing between feeder, distribution and drop cables. Capacity ranges from 12 cores for FTTH drop junctions up to 840 cores for backbone and long-haul splice points. Sealed to IP68, housings are PP+GF, PPR or metal-braced polymer with a 15 to 25-year design field life. Our passive optical component roots trace back to 1994, and the same in-house tooling and test discipline built for PLC splitters now runs the splice closure line.

what is splice closure

Two body types cover the two OSP install methods: dome (vertical) closures for pole, wall and direct-buried joints, і горизонтальний (inline) closures for manhole, handhole and figure-8 aerial splice points. Selected dome models ship pre-loaded with 1×8 or 1×16 PLC splitters and act as PON hub points inside a Quick ODN / pre-terminated FTTH deployment. Enclosures accept mechanical, heat-shrink or silicone sealing per model.

What Is a Splice Closure and How to Choose the Right Type

Dome vs Horizontal — The Two Body Types

A splice closure protects, seals and organises spliced fibers at any point along an OSP cable route. The body shape follows the physical install location, not the fiber count.

Dome (Vertical) Horizontal (Inline)
Кабельний ввід All ports on one base plate Ports at two opposite ends
Best install Pole, стіна, прямопогребний, hand-hole from top Люк, aerial figure-8 span, tray-mount inline
Typical core count 96, 144, 288 — expandable via added trays 12, 48, 96, 576, 840 — scales with body length
Access Lift the dome, all splice trays exposed Split the shell, access trays along the axis
PLC splitter loading Common (PON hub role) Less common, used mainly for pure splice

Sealing Method — Mechanical, Heat-Shrink or Silicone

  • Механічне ущільнення (compression grommet + rubber gasket): re-enterable, no torch required, fastest field install. Standard on most dome and small inline models.
  • Heat-shrink seal: highest holding force, permanent seal, common on high-count 576–840 core inline backbone closures. Requires a torch and trained crew.
  • Silicone / gel seal: used where the splice point sees standing moisture, oil or aggressive chemicals; re-enterable without heat.

How to Match the Closure to Your Field Scenario

  • FTTH drop junction on aerial figure-8 → 12-core inline mechanical seal.
  • PON hub with 1×8 or 1×16 splitter → splitter-loaded dome closure with pre-terminated ports; slots into a Quick ODN deployment.
  • Direct-buried backbone splice needing pressure test → 96/144 core dome, 100 kPa air-pressure hold, 25-рік проектного терміну служби.
  • Manhole splice with wet environment → horizontal closure with silicone sealing.
  • Long-haul or metro trunk splice, high fiber count → 576 або 840 core inline heat-shrink closure.
  • Pole splice with heavy tray load or vibration → metal-bracket dome, tray-secured for mechanical stability.

Виробничі можливості та контроль якості

Production History and Team

Fibconet’s optical communication background traces back to the early 1990s. Our passive optical component manufacturing roots start in 1994 with a PLC splitter factory; the company was formally structured in 2000 and today operates with 300+ core staff and an extended multi-site manufacturing network of up to 800 персонал та інженери across China. The same tooling and test discipline built for high-count PLC splitter production now runs the splice closure line, including injection molding of PP+GF and PPR housings, splice tray forming, and full-load assembly.

Контроль матеріалів на вході

Splice closures are only as reliable as the materials inside them. Ми контролюємо вихідний стек, а не лише етап складання:

  • Housing resin: qualified PP+GF and PPR grades with a UV stabiliser and weathering-modifier additive package dosed at pre-mix.
  • Sealing rubber and silicone: qualified grades matched to the operating temperature range and rated field life.
  • Splice trays and metal brackets: produced on dedicated tooling for dimensional consistency across production batches.
  • Passive optical parts inside splitter-loaded closures: Шицзя / Korean-source PLC chips, NTT-grade optical epoxy, CCTC ceramic ferrules, and G.657.A2 pigtail fiber sourced from major Chinese fiber brands (Fiberhome, YOFC, Hengtong).

Контроль якості

Часті запитання

Q1. What do buyers mean by “закриття зрощення”, “joint closure”, “dome can” або “熔接包”?

All four are the same product family — an outdoor enclosure that houses and seals spliced fibers along an OSP cable route. “Splice closure” і “joint closureare the standard English terms. “Dome can” і “炮筒are field slang for the dome (vertical) body style. The Chinese term熔接包refers to the same category and is common in Chinese-language RFQs from Southeast Asia and Africa.

Q2. What is the difference between a splice closure and a distribution box?

A splice closure protects and organises spliced fibers along an OSP cable route; there is no active drop-cable termination for subscribers. A distribution box (ЖИР) terminates drop cables into adapter ports and often houses the last-mile splitter. Splice closures sit deeper in the network; distribution boxes sit at the drop point closest to homes.

Q3. When should I choose a dome closure and when an inline closure?

Choose dome when cables enter from a single direction — pole-mount, кріплення на стіну, прямопогребний, or hand-hole accessed from above. Choose inline when cables enter and exit along the same axis — manhole splice, aerial figure-8 span, or tray-mount along a linear run.

Q4. What core capacity do I need?

Match the closure to the largest cable at the splice point plus a spare tray for future expansion. FTTH drop junctions typically use 12–48 core inline closures. PON access nodes use 96–144 core dome closures. Metro backbone splices use 288 ядра; long-haul trunk splices use 576 або 840 cores in heat-shrink inline bodies.

Q5. What sealing method is most reliable for a direct-buried joint?

For direct-buried and pressurised networks, use a mechanical-seal dome with 100 kPa air-pressure hold; the seal is verifiable in the field and re-enterable for future splice work. Heat-shrink is more permanent but not re-enterable without cutting.

Q6. Do you supply closures pre-loaded with a PLC splitter?

так. Dome closures can be shipped with a 1×8 or 1×16 PLC splitter pre-terminated at factory. The 1:8 / 1:16 PLC Splitter Dome model is rated for 22,000 Н / 10 cm cable retention so the housing tolerates heavy drop-cable pull. Splitter chips are Shijia or Korean-source, and pigtails use G.657.A2 fiber from major Chinese fiber brands.

Q7. What is the outdoor field life?

PP+GF and PC+ABS housings with a UV stabiliser additive package hold 15 до 25 years of outdoor service, depending on model. Ask us for the specific model’s material spec if your project tender requires a stated design life.

Q8. Do you provide test reports and international standard conformity documents?

так. IEC 61753-1, YD/T 814 and GR-771 test reports are available per model. Raw material RoHS reports ship by default. Market-entry certificates such as CE, ДОСЯГНІТЬ, в, ETL, СЛР, ANATEL, CCA and TLC are issued per model and per target market. If a certificate you need is not already on file, we can arrange third-party testing at project scale.

Q9. What is your MOQ and typical lead time?

MOQ starts at 100 pcs on standard configuration; custom builds are typically 500–1,000 pcs. Standard orders ship in 15–25 days; custom builds in 25–40 days. [Уточнюється: confirm exact values per model at RFQ stage.]

Q10. Do you supply mounting hardware for pole and manhole install?

так. Pole-mount and wall-mount hardware is included on the dome closures. Aerial figure-8 mounting kits for inline closures are supplied on request. Manhole tray mounts and cable-management brackets are quoted with the closure.

Q11. Can these splice closures be used in a Quick ODN or pre-terminated FTTH deployment?

так. Our splitter-loaded dome closures — the 1:8 / 1:16 PLC Splitter Dome and the pre-terminated FAT closure — act as PON hub points inside a Quick ODN system. They pair with our pre-terminated drop cables, MPO Hubs, sub boxes and asymmetric splitters to reduce on-site splicing, cut installation labor, and make FTTH rollout more predictable. If your project is a new FTTH build in a labor-cost-sensitive market, ask for a matched Quick ODN configuration when you send the RFQ.
