Model of fiber optic splice closure

The model number of the fiber optic splice closure is 2178, with specific variants including XSB, XLB, S, SL, LS, LL, and XL. The 2178 family of fiber optic splice closures is designed for reliable protection of fiber optic networks and offers multiple configurations to meet diverse deployment needs, including aerial, buried, underground, vault, and building entrance applications (Corning/3M). Each closure in the 2178 family is optimized for ribbon cables but is suitable for all cable types, including loose buffer tube, tight buffer tube, central tube, discrete fiber, and armored or dielectric cables.

Variants and Features

Models: XSB, XLB, S, SL, LS, LL, XLVersions: Flame-retardant and non-flame-retardantApplications: Supports inline and butt splicing, mechanical and fusion splicingDesign: Reusable gaskets for easy re-entry, flexible tray systems for positional or fixed splice inserts, multiple cable entry ports for system expansion The 2178 closure family allows network operators to scale splicing capacity and cable entry ports as needed, providing flexibility for growing networks while simplifying installation and maintenance. Each variant is tailored to different network sizes and environmental conditions, making it a versatile solution for modern fiber optic deployments.
