Inside Plant: FieldSmart FxDS Cable Assemblies


Quality second to none

No matter what kind of traffic your network carries, the success of your business comes down to the quality of your cable plant. Clearfield cable assemblies are used in the most demanding environments, from global manufacturing to emerging communications. Clearfield fiber assemblies go beyond industry standards for insertion loss and return loss performance. Our design processes pay strict attention to geometries and our end-face cleanliness is second to none. We can design and manufacturer cable assemblies for just about any application, meeting your requirements for cost, performance, reliability and rapid delivery.

Simply the best patch cords around Clearfield offers cable assemblies in custom and standard lengths, ranging from simple multimode and single mode patch cords, to some of the most complex assemblies in inside and outside plant environments, including distribution, breakout style, drop cable and drop node. Automated polishing processes ensure precise control of polish radius, apex offset and fiber undercut. Our process engineers have perfected termination techniques for all types of specialty cable designs, including ribbon fiber, high-fiber count, and ruggedized. We support most industry standard connector types, including the industry’s latest hardened fiber optic connectors (HFOC).

Clearfield offers copper cable assemblies, ranging from category 5e and 6 patch cords, through DS1 telcos to DS3 coax assemblies, along with a variety of complex specialty copper assemblies.

Distribution Assemblies

Clearfield distribution cable assemblies are used where multi-fiber tight-buffered constructions are required for density. These assemblies combine the bandwidth capacity of individual cable assemblies in one easy- to-use assembly, and can be used in OSP patch/splice applications.

Intrafacility (IFC) cable is the de facto standard for central office/head-end multi-fiber applications. This compact and rugged construction is perfectly suited for high fiber count trunk cables, in-panel assembly, communication closets, raceway, and dropped ceiling/ raised floor architectures.

Indoor Jumpers

A fiber jumper, sometimes called a fiber patch cord is a length of fiber cabling fitted with connectors at each end. They are used to connect end devices or network hardware.

Fiber assemblies are used in a variety of carrier networks and private network environments. The key to manufacturing high-performance fiber assemblies is controlling polish radius, apex offset and fiber undercut. Clearfield monitors its automated polishing process to exceed industry specifications for insertion and return loss, ensuring a top-quality product.

VOA & Patch Cord Splitter

A variable optical attenuator (VOA) is a device designed to attenuate an intensity or power level of an input optical beam in a controlled manner to produce an output optical beam with different attenuated intensities. Variable optical attenuators play an important role in the implementation of modern information networks having optical interconnects. In fiber optic communication systems, variable optical attenuators are broadly employed to regulate the optical power levels to prevent damages to the optical receivers caused by irregular optical power variations.

Fiber optic couplers are optical devices that connect three or more fiber ends, dividing one input between two or more outputs, or combining two or more inputs into one output.

Clearfield’s VOA’s and patch cord splitters are optical components that are up-jacketed to 3mm and terminated with any industry standard connectors.

  • Outputs and Inputs available in any industry standard connector type

Buildout Attenuators

Fiber optic attenuators are designed to introduce a specific amount of signal loss into an optical circuit. These products provide attenuation at a mated pair connection and are used for signal budgeting and power equalization.

Clearfield provides both build-out and inline attenuators in all industry standard interface and attenuation values.

  • Build-out or in-line variations provide necessary attenuation at network interconnect
