FAQ

144 core or 288 core - which should I choose?

144 core fits most metro and 5G backhaul splice points. Choose 288 core for very high-density trunk routes, cross-connect cabinets, or when you need substantial spare capacity for 10 years of growth.

How many splice trays fit inside?

Standard 12 trays of 12 cores each = 144 fibers. Most models accept up to 16 trays for future expansion to 192 fibers.

Can it be wall-mounted in a manhole?

Yes. The horizontal type is commonly wall- or floor-mounted in handholes and manholes. The dome type is typically pole- or aerial-mounted.

What is the MOQ?

MOQ is 50 pcs for neutral boxes. OEM with your logo: 500 pcs. Samples 1-10 pcs available.
