Slide 1: Rodent Resistant Fiber Optic Cables
Rodent Resistant Fiber Optic Cables
Slide 2: Introduction
Introduction • Optical fiber cables can be exposed to a number of potential hazards in an indoor or outdoor environment. • Damage can occur in a relatively short period of time • The type and severity of damage depends upon several factors including species, type of installation/application, and the
Slide 3: Competition
Competition • Competitors offer a variety of armoring for rodent protection – Corrugated Steel Tape (CST) – FRP – Steel Wire – Nylon Jacket – Chemical Repellents • Corning offers a dielectric armor in their Mic Cables, but make no statement about them being rodent resistant. They only mention crush
Slide 4: Competition
Competition • Belden lists a percent effective chart for various types of armoring. • There is no mention on how they determined the results. 4
Slide 5: Armoring - OCC
Armoring - OCC • CST – Excellent: Direct Burial, Aerial, Subterranean Tunnels – Caution: Conduit, Cable Tray – Not Recommended: Deployable • FRP – Excellent: Deployable, Subterranean Tunnels, Conduit, Cable Tray – Good: Aerial – Not Recommended: Direct Burial • Bitterant (non-toxic) – Excellent: Sub
Slide 6: Know Your Threat!
Know Your Threat! • Most important thing to understand is what will be the threat to the cable. • Once you know what the threat is, the correct armoring can be applied. • Some armoring works great for certain applications, but some armoring may attract mammals. - Example: Bitterant – May attract Squ
Slide 7: Know Your Threat!
Know Your Threat! Some installers will do anything to make it look like a cable or rodent issue and not an install issue. 7
Slide 8: Direct Burial
Direct Burial • Only Corrugated Steel Tape (CST) is the only armoring recommended for Direct Burial • Designed for use with burrowing and non-burrowing Rodents • Non-CST cables do not offer adequate protection from burrowing rodents 8 FRP subjected to Gopher Ground Hog Gophers
Slide 9: Aerial
Aerial • Squirrels are typically the culprit • Lashing CST provides best protection – Requires Grounding • Lashing FRP can be an alternative • Bitterant not really recommended for Squirrel resistance • Squirrels equate bitter taste to bitter tasting nutshell. They will eat through the bitterant jack
Slide 10: Subterranean Tunnels
Subterranean Tunnels • Rats and Mice are typically found in these locations • FRP is used to deter rats and mice • Bitterant can be added for further rat and mice resistance • LSZH may be required – DX series FRP LSZH Riser from 2-12 Fibers, 18-48 fibers with just LSZH – DX series CST LSZH Riser fro
Slide 11: Conduit/Cable Tray
Conduit/Cable Tray FRP • Rats and Mice are typically found in these locations • FRP is used to deter rats and mice • Bitterant can be added for further rat and mice resistance • DX Series 2-144 fibers with FRP and Riser Rating CST • CST Not typically recommended but can be used • Increases Diameter
Slide 12: Deployable
Deployable Dielectric • Wide range of threats in this environment • FRP gives maximum protection for deployable surface rodent protection • Low Luster V jacket with appropriate color – Designed to make cable “blend in” with surroundings (prevent deployable cable appearing like a snake) – Coyotes, Ja
Slide 13: Termite Resistance
Termite Resistance • Specific threat for selective locations • Termites can be very aggressive in attacking an outer jacket • DX Series cable – Hard Elastomer inner jacket – PVC Outer Sacrificial Jacket 13
Slide 14: Field Trials – Rodent Resistance
Field Trials – Rodent Resistance • Nobody in North America testing fiber optic cable rodent resistance with caged rodents • OCC conducting field trial. Currently on-going. • All cables located at OCC in Roanoke, VA • Multiple cable types laid in parallel next to pathway for burrowing rodents Jacket
