Very high capacity closure for metro core, central office cross-connect and large trunk routes. Dome heat-shrink and horizontal 4-in 4-out designs, IP68, built for large fiber counts.
Two very large designs. The dome heat-shrink for cost-effective aerial trunk joints, and the horizontal 4+4 for high-port-count duct and buried cross-connects.
Extra-large dome closure, 1 inlet 6 outlet. High-capacity aerial splice point for trunk cable routes.
Eight-port horizontal closure for large cross-connect splice points in ducts and manholes.

Where our customers deploy the 288-core closure.
Main splice points in city fiber core rings and POP sites.
Between feeder distribution frames and outside plant cables.
Land-based splice points for undersea and long-haul cable terminals.
288 core is the standard for metro core and large trunk splice points. Choose 576 core only for very high-density central office cross-connects or long-haul landing stations with massive fiber counts.
Standard 24 trays of 12 cores each = 288 fibers. Tray layout is configurable based on fiber ribbon and single-fiber splicing.
Yes. The horizontal type is designed for wall or floor mounting in manholes and handholes. The dome type is typically pole- or aerial-mounted.
