The FSC-D22 Dome Fiber Optic Splice Closure is a high-capacity, rugged enclosure designed to protect and manage fiber splicing in outdoor network environments. Constructed from durable engineering plastics, it offers excellent resistance to environmental stress, making it suitable for long-term deployment in aerial, underground duct, and direct burial applications.

Featuring a dome-style mechanical sealing system, the closure ensures reliable protection against moisture, dust, and external impact while remaining fully re-enterable for maintenance and network expansion. With support for up to 144 fibers (or up to 432 fibers in ribbon configuration), it is ideal for backbone, distribution, and access network splice points, including through, branch, and mid-span installations.

Q1: What is the maximum fiber capacity of this closure?
It supports up to 144 fibers for standard splicing and up to 432 fibers for ribbon fiber configurations.

Q2: Can the closure be reopened after installation?
Yes. The mechanical seal design allows the closure to be re-entered multiple times for maintenance or expansion.

Q3: What types of installation environments is it suitable for?
It is designed for aerial, underground duct, and direct burial applications.

Q4: What cable diameters are supported?
The closure supports cable diameters ranging from 8 mm to 20 mm.

Q5: Is it compatible with ribbon fiber splicing?
Yes. It supports ribbon fiber configurations with higher capacity.

Q6: What makes the dome design advantageous?
The dome structure provides better sealing performance, improved internal space management, and enhanced protection against environmental conditions.
