Fiber Optic Inline Closures are used to protect straight-through and branching splices in aerial, underground, wall-mounted and duct network sections. This model range covers compact low-count closures for small repairs and drop connections, as well as higher-capacity versions for mainline distribution, access network branching and FTTH deployment projects.
UPCOM inline splice closures are built to keep fibre routing organized, protect splice points against moisture and mechanical stress, and give installers the right tray and port layout for the cable diameter actually used on site.
An inline closure is the right choice when the cable route continues through the enclosure and splice protection has to stay compact, sealed and serviceable. Compared with dome-style alternatives, inline bodies are often preferred where entry and exit direction matters, where installation space is limited, or where a flatter closure layout is easier to mount and maintain.
From 4-fibre repair points to 96-fibre multi-tray versions, the series covers both low-count access work and larger distribution links.
Depending on the model, round ports support small drop cables, standard access cables and larger feeder diameters.
Suitable models can be adapted for hanging, wall mounting or pole mounting, depending on the closure version and accessory set.
Tray-based layouts keep splices organized, reduce stress on fibre routing and make later service work more controlled.
This range includes compact closures for low-count splicing, standard inline units for access networks, and higher-capacity closures with tray-based configurations for heavier distribution work. Optional accessories vary by model and may include hanging hooks, wall mounting kits, pole mounting kits, air valves, grounding devices and SC adaptor accessories.
Small-format inline closure for very limited splice counts and narrow cable entries.
A straightforward option for lower-count splicing where compact dimensions still matter.
Suitable where splice count increases and different round entry diameters must be considered.
A balanced choice for 96-fibre applications that need tray-based organization and standard round ports.
Good where tray management is needed but the closure footprint should remain relatively controlled.
Designed for higher-count projects where more tray organization and broader cable entry sizes are needed.
A practical mid-capacity unit where tray layout and optional adaptor accessories may be useful.
Long-body inline format for moderate splice counts with standard wall-mount accessory compatibility.
Built for low-count fibre splicing where multiple drop-style ports are part of the connection layout.

| Model | Splice capacity | Tray | Port / cable entry summary | Best fit |
|---|---|---|---|---|
| UP-ILC-F02 | 4 fibres | - | 2 round ports, up to Ø6 mm | Compact repair and very low-count splicing |
| UP-ILC-F01 | 12 fibres | - | 4 round ports, up to Ø10 mm | Small access closures and short branch sections |
| UP-ILC-102 | 96 fibres | - | Round port options up to Ø16 mm and Ø13 mm | Higher-count branch and feeder distribution work |
| UP-ILC-106 | 96 fibres / 4 trays | UP-TRAY-X3 | 4 round ports, up to Ø16 mm | Tray-managed distribution splicing |
| UP-ILC-101 | 96 fibres / 4 trays | UP-TRAY-023 | Entries up to Ø14 mm and Ø12 mm | Compact-body 96-fibre tray layout |
| UP-ILC-103 | 96 fibres / 8 trays | UP-TRAY-023 | Round entry options up to Ø20 / Ø16 / Ø13 mm | Larger tray count and broader cable range |
| UP-ILC-502 | 48 fibres / 4 trays | UP-TRAY-037 | Round entry options up to Ø20 / Ø16 / Ø13 mm | Mid-capacity closure with accessory flexibility |
| UP-ILC-131 | 48 fibres / 2 trays | - | 4 ports, one cable per port up to Ø16 mm | Access network branches and wall-mounted routes |
| UP-ILC-132 | 8 fibres | - | Mixed ports for feeder and drop cable entries | FTTH drop distribution and subscriber connections |
Inline closures are usually selected where splice protection has to follow the cable path cleanly and where installers need a predictable entry-to-exit route for feeder, distribution or drop cables.
Useful on poles or suspended routes where a straight-through body is easier to position, secure and reopen during maintenance work.
Suitable for handholes, chambers and protected buried sections where reliable sealing and organized tray routing are required.
Relevant for building entry points, riser transitions, indoor-outdoor handover sections and protected service zones.
Low-count and multiport versions help manage customer-side branching and smaller distribution tasks without oversized hardware.
Start with the actual project constraint, not just the highest splice capacity on the table. The right closure is the one that matches fibre count, cable outer diameter, entry layout, mounting method and future maintenance access at the same time.
