Key Features

Engineered For Performance

Compact Multi-Fiber Design

Multiple 900um tight-buffered fibers in a single jacket provide higher fiber density than breakout cables while maintaining direct access to individual fibers for termination.

Riser & Plenum Rated

Available in OFNR (riser) and OFNP (plenum) fire-rated versions, meeting NEC requirements for installation in building risers and air-handling spaces.

Easy Mid-Span Access

Common jacket design allows mid-span cable entry to access individual fibers at any point along the cable run, simplifying multi-floor distribution installations.

Standard Color Coding

All fibers color-coded per TIA-598 standard for reliable identification. Available in single-mode (yellow), OM1/OM2 (orange), and OM3/OM4 (aqua) configurations.

Typical Applications

01

Building Riser Backbone

Vertical fiber backbone in multi-story buildings, connecting the main distribution frame in the basement to telecommunications rooms on each floor.

02

Horizontal Distribution

Floor-level fiber distribution from telecommunications closets to work area outlets, supporting enterprise LAN and data center structured cabling.

03

Data Center Backbone

Intra-facility fiber backbone connecting main distribution areas to horizontal distribution areas within data centers and large enterprise network environments.
