48-Core Horizontal Inline Fiber Optic Splice Closure (3-in-3-out)
The workhorse for FTTH backbone and distribution networks. Dome vertical and horizontal inline designs, multi-port, IP68, ready for aerial, pole-mount, duct and buried deployment.
Two popular 48-core designs. The dome mechanical for re-openable aerial joints, and the horizontal 3-in 3-out for multi-branch distribution.
Re-openable dome closure, 2 inlet 2 outlet. The most common choice for aerial FTTH backbone splice points.
Six-port horizontal closure for multi-branch distribution - splits one feeder into three distribution routes.

Where our customers deploy the 48-core closure.
Main splice points connecting ODF in central office to neighborhood distribution.
Hybrid fiber-coaxial (HFC) network nodes and fiber backhaul.
Power grid, railway and pipeline optical monitoring links.
48 core fits most FTTH backbone splice points. Choose 96 core for large neighborhoods, dense urban deployments, or when you need spare capacity for future growth.
Standard 4 trays of 12 cores each = 48 fibers. Most models accept up to 6 trays for future expansion to 72 fibers.
Yes. All our 48-core closures are IP68 rated and suitable for direct burial. We recommend the horizontal type for buried routes.
MOQ is 50 pcs for neutral boxes. OEM with your logo: 500 pcs. Samples 1-10 pcs available.
