Fiber Optic Splice Closure Manufacturer — Dome and Inline, 12 nei 840 Cores

Fibconet produsearret 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.

Two body types cover the two OSP install methods: dome (vertical) closures for pole, wall and direct-buried joints, en horizontaal (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.

12 Splice Closure Models We Manufacture

Groep 1 — Dome (Vertical) Splice Closures

Cylindrical body with a single base plate carrying all cable ports. Best suited to pole-mount, wall-mount and direct-buried joints where cables enter from one end. The two splitter-loaded models below double as PON hub points inside a Quick ODN deployment.

Groep 2 - Horizontaal (Ynline) Splice Closures

Langwerpige lichem mei kabel havens oan beide úteinen. Foarkar foar put, hângat, loftfiguer-8 span en eltse splice punt dêr't kabels ynfiere en útgean yn deselde as.

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.

Sealing Metoade - Mechanical, Heat-Shrink of Silicone

• Mechanyske seal (kompresje grommet + rubberen pakking): opnij ynfierber, gjin fakkel nedich, fluchste fjild ynstallaasje. Standert op de measte koepel en lytse inline modellen.
• Heat-krimp seal: heechste holding krêft, permaninte segel, mienskiplik op hege tellen 576–840 kearn inline rêchbonke slutingen. Fereasket in fakkel en oplaat bemanning.
• Silicone / gel seal: brûkt dêr't de splice punt sjocht steande focht, oalje of agressive gemikaliën; re-enterable sûnder waarmte.

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 luchtdruk hâlden, 25-jier design libben.
• Manhole splice with wet environment → horizontal closure with silicone sealing.
• Long-haul or metro trunk splice, high fiber count → 576 of 840 core inline heat-shrink closure.
• Pole splice with heavy tray load or vibration → metal-bracket dome, tray-secured for mechanical stability.

Manufacturing kapasiteit en kwaliteit kontrôle

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 Personiel en yngenieurs 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.

Upstream Materiaal Control

Splice closures are only as reliable as the materials inside them. Wy kontrolearje de streamopstap yn stee fan allinich de montagestap:

• 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: Shijia / 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).

Kwaliteitsbeweitsing

• Air-pressure hold test on every assembled dome closure before shipment (100 kPa on rated models).
• Waterproof and dustproof test to the rated IP68 grade on production samples per batch.
• Impact test per rated IK grade on housing samples.
• Cable retention pull test per rated axial load (oant 22,000 N / 10 cm on splitter-loaded dome).
• Termyske syklus en vochtigheid test per model kwalifikaasje.
• Full-load tray test mei splice trays en splitters ynrjochte, om te ferifiearjen dat kabelbehear passe ûnder echte havenbelêsting.

Sertifikaasjes en neilibjen

Fibconet wurket ûnder in yntegrearre ISO 9001 / ISO 14001 / ISO 45001 behear systeem covering kwaliteit, miljeu en beropssûnens & feilichheid. RoHS-rapporten foar grûnstof wurde standert levere mei elke ferstjoering.

Neilibjen fan produktnivo wurdt útjûn per model en per doelmerk. Ofhinklik fan it model list en bestimming lân, wy kinne stypje DIZZE, RoHS, BERIKKE, de, ETL, CPR, ANATEL, CCA, TLC en oare dokuminten foar merkyngong. Tapasbere test rapporten tsjin IEC 61753-1, YD/T 814 en Telcordia GR-771 referinsjenoarmen wurde levere op projektskaal.

Faak stelde fragen

Q1. Wat bedoele keapers mei “splice sluting”, “mienskiplike sluting”, “koepel kin” of “Welding pakket”?

Alle fjouwer binne deselde produktfamylje - in iepenloftspul dy't sletten fezels huzen en fersegele lâns in OSP-kabelrûte. “Splice sluting” en “mienskiplike sluting” binne de standert Ingelske termen. “Dome kin” en “barrel” binne fjild slang foar de koepel (vertical) body style. De Sineeske term “Welding pakket” ferwiist nei deselde kategory en is gewoanlik yn Sineesktalige RFQ's út Súdeast-Aazje en Afrika.

Q2. Wat is it ferskil tusken in splice sluting en in ferdieling doaze?

In splice sluting beskermet en organisearret spliced ​​fezels lâns in OSP kabel rûte; der is gjin aktive drop-kabel beëiniging foar abonnees. A distribution box (FET) 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, muorre-mount, Direkt begroeven, or hand-hole accessed from above. Choose inline when cables enter and exit along the same axis — manhole splice, loftfiguer-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 kearnen; long-haul trunk splices use 576 of 840 kearnen yn waarmte-krimp inline lichems.

Q5. Hokker sealing metoade is it meast betrouber foar in direkte begroeven joint?

Foar netwurken mei direkte begraven en ûnder druk, brûke in meganyske-seal koepel mei 100 kPa luchtdruk hâlden; it segel is te kontrolearjen yn it fjild en opnij ynfierber foar takomstige splice wurk. Heat-krimp is permanint, mar net opnij yn te fieren sûnder te snijen.

Q6. Hawwe jo leverje closures pre-laden mei in PLC splitter?

Ja. Dome closures kinne wurde ferstjoerd mei in 1 × 8 of 1 × 16 PLC splitter foarôf beëinige by fabryk. De 1:8 / 1:16 PLC Splitter Dome model wurdt rated foar 22,000 N / 10 cm kabel fêsthâlden sadat de húsfesting tolerearret swiere drop-kabel pull. Splitter-chips binne Shijia of Koreaansk-boarne, en pigtails brûke G.657.A2 fiber út grutte Sineeske fiber merken.

Q7. Wat is it bûtenfjild libben?

PP + GF en PC + ABS húsfesting mei in UV stabilisator additive pakket hold 15 nei 25 jierren fan bûtentsjinst, ôfhinklik fan model. Freegje ús om de materiaalspesifikaasje fan it spesifike model as jo projekttender in oanjûn ûntwerplibben fereasket.

Q8. Biede jo testrapporten en ynternasjonale standertkonformiteitsdokuminten?

Ja. IEC 61753-1, YD/T 814 en GR-771 test rapporten binne beskikber per model. RoHS-rapporten wurde standert ferstjoerd. Sertifikaten foar merkyngong lykas CE, BERIKKE, de, ETL, CPR, ANATEL, CCA en TLC wurde útjûn per model en per doelmerk. As in sertifikaat dat jo nedich hawwe is net al op triem, wy kinne testen fan tredden op projektskaal regelje.

Q9. Wat is jo MOQ en typyske levertiid?

MOQ begjint at 100 pcs op standert konfiguraasje; oanpaste builds binne typysk 500-1,000 pcs. Standert oarders ferstjoere yn 15-25 dagen; oanpaste builds yn 25-40 dagen. [TBC: befêstigje eksakte wearden per model by RFQ-poadium.]

Q10. Hawwe jo leverje mounting hardware foar peal en put install?

Ja. 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?

Ja. 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.
