144-Core Dome Fiber Optic Splice Closure
The 144-Core Dome Fiber Optic Splice Closure is a vertical outdoor fiber joint enclosure designed to splice, protect and organize up to 144 optical fibers. Its dome-style housing keeps the cable-entry area at the base while multiple splice trays are arranged inside the enclosure for fiber routing and joint management.
It is suitable for telecom, FTTx and access-network branch points where feeder and distribution cables need a protected outdoor splice location with enough capacity for current connections and future expansion.
Why Choose the 144-Core Version?
This capacity is useful for network points handling several fiber cables, multiple branch routes or planned expansion. It provides more room for splice organization than smaller closures without moving to a much larger cabinet-style distribution product.
Up to 144 fibers for higher-capacity outdoor splice points
Dome structure suited to feeder and branch cable connections
Multi-tray layout for grouped splice management
Base cable-entry arrangement for outdoor cable routing
Suitable for new installations, network expansion and replacement projects

Capacity Is Only Useful If Future Access Stays Manageable
For a 144-core closure, the practical concern is not only whether all fibers fit inside the housing. The splice trays and cable routes also need to remain clear enough for technicians to reopen the closure, add a new branch or work on one splice group without disturbing completed connections.
Where future network growth is expected, spare tray and routing space can be included when the closure configuration is confirmed.
Typical Applications
FTTx feeder and distribution cable joints
Outdoor telecom backbone splicing
Access-network branch points
Aerial and pole-mounted fiber routes
Duct and underground fiber networks
Network expansion and cable repair projects
Horizontal or Dome Closure?
This dome structure is a good fit when cable entries are concentrated around one joint point and several feeder or branch cables need to be managed inside the same enclosure. For inline cable routes where fibers mainly continue through opposite sides of the joint, see our 96-Core Horizontal Fiber Optic Splice Closure.
Send Us Your Cable and Splice Requirement
Provide the required fiber count, cable quantity, cable diameter, branch arrangement, installation method and order quantity. If the product is being selected for an existing network, a site photo or cable-route drawing can help us confirm the suitable closure configuration before quotation.
