Field-proven installation guides, checklists and port configuration tips for fiber optic splice closures. Written by our OSP engineers who have supported FTTH deployments across Latin America.
Step-by-step articles covering aerial, underground, pole-mount and handhole installation of dome and horizontal splice closures. New guides added monthly.
Site selection, port sizing, tray management, torque and water testing — the step-by-step checklist our crew uses on every FTTH joint.

Aerial vs Underground Splice Closure Installation Guide
Aerial vs Underground Splice Closure Installation: A Field Crew Checklist
Choosing between aerial and underground deployment is only half the job. The other half is installing the fiber optic splice closure correctly the first time — because once t

Choose the Right Port Configuration for Your Splice Closure
How to Choose the Right Port Configuration (Inlet/Outlet) for Your Splice Closure
"How many ports do you need?" is one of the first questions our engineers ask on every splice closure inquiry. It sounds simple, but picking the wrong configuration m

Common installation questions answered by our engineering team.
Clearance heights, bracket orientation, service loops and closure orientation for overhead cable routes.
Tray mounting above sump water, dome vs horizontal choice for flooded chambers, lid labeling.
Matching cable OD to grommet inserts, blank plugs for unused ports, bend radius ≥10× cable OD.
Mechanical bolt torque, heat-shrink even heating, soapy water test and OTDR verification before backfill.
Typically 60–80 cm below finished grade, on a sand bed, with a warning tape above. In areas with vehicular traffic, add a concrete slab or use a duct entry into a handhole instead.
No. Heat-shrink closures are single-use. If your network may need future re-splicing, choose a mechanical-seal dome closure that can be opened and re-bolted without replacing the seal.
Typically 2–3 N·m in a star pattern. Over-torquing distorts the rubber and creates leak paths; under-torquing lets water in. A regular wrench by hand is enough — don't use a torque stick set too high.
Most neighborhood nodes use 1-in-4-out: one feeder in, four distribution legs out to 32–64 homes each. For MDUs or dense blocks, plan 1-in-6 or 1-in-8.
Our engineers will recommend the right closure, port configuration and sealing type for your project.
