FieldShield is a new fiber delivery method aimed at reducing the cost of broadband deployment.
FieldShield takes industry standard glass and makes it easier and less expensive to install. It starts by teaming a ruggedized microduct through which a flexible fiber cable is placed. From the early days of deep fiber installations, through the beginnings of FTTH, to the current methods of today, fiber delivery solutions have remained relatively unchanged. Fiber has traditionally been pulled through ¾” to 1-1/4” conduit. This delivery method is expensive and unsightly as burying the large conduit is labor intensive and tears up the surrounding area. While original deployments centered around large count fiber, today’s fiber drops bring small count fiber from the access point directly to the customer prem. Today’s customer is demanding the least intrusive solution possible.
Pushable fiber technology continues Clearfield's legacy of user-defined configurability, enabling users to push or pull specially designed hardened fiber cable assemblies through a series of ruggedized microducts, delivering fiber to even the hardest to reach environments. By using only a 10mm microduct, fiber can be buried with the simplest and least invasive trenching techniques. In addition, fiber can be run directly to the antenna or radio head on a cell tower, while being fully protected from the harshest elements. Ease of field restoration is ensured regardless of installation method or environment in which it is installed. Should the microduct be cut for whatever reason, the fiber is easily removed, the duct repaired with a simple coupler, and fiber pushed back into place with limited interruption or inconvenience.
FieldShield starts with a Ruggedized Microduct designed to support all aerial, direct bury, and inside plant “last mile” needs. Created from the most rugged HDPE polymers, FieldShield Microduct is strong enough to be placed using traditional methods of boring and plowing, allowing you to leverage your existing conduit placement equipment, as well as newer, less disruptive technologies such as micro trenching or saw cutting.
What’s more, due to its high column strength, FieldShield microducts can be deployed as a rod directly within a larger occupied duct that was previously thought exhausted. The lack of space and the costs associated with constructing new pathways through the riser space can be just as prohibitive as digging up city streets.
Available for aerial and buried environments in the OSP as well as in a plenum configuration for riser environments, FieldShield provides the pathway to quickly deliver a crush-resistant FieldShield pushable fiber assembly.
Whether you choose to push or pull the fiber into the FieldShield Microduct, the PBT jacket of Clearfield's FieldShield Pushable Fiber easily slips through the microduct's smooth inner wall. Utilizing OFS bend-insensitive glass, FieldShield Pushable Fiber is available in a variety of fiber counts: 1 to 12 fibers in a 3mm jacket and up to 24 fibers in a 4mm jacket.
Available in bulk reels or factory terminated, FieldShield offers total installation flexibility. FieldShield Pushable Fiber can be pushed by hand up to 100 feet or to distances up to 500 feet for direct bury applications and 300 feet for plenum and riser environments with the use of the FieldShield Assist Module, Clearfield’s cordless drill-driven machine. In situations where required installation distances make pushing by hand labor-intensive, the FieldShield Assist Module provides the extra boost to simplify installation. Eliminating potential catastrophic damage due to buckling or folding of the fiber optic cable, this hand-held tool houses an integrated clutch that engages when resistance reaches a threshold that could damage the cable. Longer installation distances can be accomplished through push/pull methods as all microduct products are supplied with a 50lb pre-placed pull string.
A factory pre-connectorized FieldShield Pushable Connector eliminates costly labor in the field and presents reliable, consistent and guaranteed performance along with lower installation costs. After being installed in the microduct, the slip-resistant protective housing is removed and the LC or SC connector snaps together - all in seconds, providing the most cost-effective, tech-friendly means of installing optical fiber without jeopardizing fiber protection.
The FieldShield Multiport SmarTerminal extends the reach of FieldShield optical fiber to the hardened connector marketplace. Teaming a FieldShield Pushable Connector with a field-installable, tool-less smart housing that provides a water tight seal decreases installation and maintenance time, while providing superior durability and reliability in the drop segment of the network. These new solutions, FieldShield Hardened Connectors and the FieldShield Multiport SmarTerminal, bring together the advantages of hardened connector technology with the ease of use and cost reductions associated with pushable fiber.
Traditional hardened connector technology is bulky and requires the use of flat drop cables, which are stiff and difficult to store. With the FieldShield solutions, the form and fit of the SC connector is maintained, slack storage is integrated within the device, and restoration and troubleshooting is greatly reduced as field restoration is easily performed without retrenching.
Pushable fiber technology is a crucial element of a total fiber protection system. Clearfield completes the product portfolio with the FieldSmart platform of fiber management, protecting fiber from the inside plant through the outside plant and all the way to the access network with a full line of panels, frame, cabinets, and wall boxes. At the heart of the FieldSmart architecture is the Clearview Cassette. Teaming FieldShield with the Clearview Cassette takes the value of this drop cable technology and extends it to multi-fiber deployments. Clearview Cassettes are available pre-terminated with a FieldShield Pushable Cable assembly, ready to be routed through microduct, and back to the splice point.
The FieldSmart Small Count Delivery (SCD) Case provides configuration flexibility in the distribution of fiber with an innovative, intuitive and modular approach, while utilizing proven, traditional, scaled-closure techniques. Designed so that FieldShield Pushable Fiber can be pushed directly into the Clearview xPAK, this enclosure reduces the labor time of installation while ensuring end-to-end fiber protection.
Optimized to support or house FieldSmart fiber management products and the FieldShield Pushable Fiber portfolio, CraftSmart Pedestals and Vaults provide turn-key physical protection at the access point of the network in above-ground installations.
