Fiber Optic Splice Closures - Last Mile Access

Fiber splice closures for fast deployment of fiber networks that stand the test of time

Closures are used at the fiber splice points to house and protect the fibers and value add modules like passive splitters and xWDM. The Commscope offering provides solutions for the three areas where fiber is deployed - the feeder, distribution, and access networks. Each of these areas have specific requirements.

The FOSC series of closures is a versatile and proven platform that can be deployed in multiple environments and all segments – aerial, pedestal, buried, and underground – as well as different splicing applications (expressed, tap-off, branch and repair).

The FIST series proven platform is known for its sealing, ease of use features and flexibility, mainly applied in the feeder and distribution network where transient fiber management is a driver. FIST fiber trays and organizers efficiently handle single fibers and ribbon fibers.

TENIO is a proven platform featuring tool-less, rapid installation and easy maintenance, and address future requirements for the distribution and access networks. They accommodate several fiber cable constructions and can be deployed in aerial, pedestal, handhole or manhole environments.

Splice Closures In-Line (SCIL) are spliced in-line with the network feeder cable, and are typically used in the distribution and access (customer drop) part of the network. Available in three sizes, they are suitable for numerous fiber splicing applications. 

The OFDC family consists of three different series of closures able to accommodate a wide range of distribution and drop cables, thus responding to virtually all application requirements. Each series has a common housing for different connectivity solutions and easy field handling.

Small fiber count access splice closures complement CommScope’s  comprehensive portfolio that can handle all fiber splicing applications, configurations, and form factors in the last mile.

With over 30 years of experience and satisfied customers around the world, CommScope can provide fiber splice closures that keep your network running even in the harshest conditions.
