PVC Telephone Duct Type C

PVC Type C telephone duct is a heavy-wall rigid PVC conduit designed specifically for telecommunications infrastructure. It provides a durable, long-term pathway for copper and fiber optic cables in underground duct bank systems, with a factory-installed bell end for secure joint assembly without separate couplings. Galloway stocks Type C telephone duct from Prime Conduit.

Features

The specifications below reflect a duct built for long, stacked underground runs — rated to the telecom duct standards utilities call out by name, joined by factory bell ends for fewer connections over distance, and spacer-compatible for multi-duct bank configurations.

Loose Tube - OSP Backbone, Feeder & Distribution

Fujikura Ribbon Fiber Splicing kit 6-22-26-8090 Medium

Color-coded loose buffer tubes

Protect individual fibers from mechanical and environmental stress; stranded designs carry 6 to 24 tubes, central-tube designs a single tube

More information chevron_right

Single-mode OS2 (G.652.D) standard, G.657.A1 for tighter bend routing;

OFS AllWave ZWP fiber gives zero water peak across the full wavelength spectrum

Gel-free DryBlock construction (OFS)

Reduces splice prep time by up to 80% vs. gel-filled designs

Jacket and construction options span single jacket (SJ) through double-armored (DA)

Corrugated steel tape armor for direct-burial without conduit or in rodent-prone areas; OFS Fortex DT Light Armor is gel-free and mass-fusion-ready

All-dielectric ADSS variant for aerial self-support

No messenger wire, no grounding on energized power lines; aramid strength members support spans to ~1,500 m depending on loading; OFS PowerGuide DT double-jacket eliminates all gels

Fiber counts from 12 to 864

Standard reel lengths 1 km and 2 km; multimode OM3/OM4 available for campus and data center interconnect

All-dielectric ADSS

All-dielectric ADSS variant for aerial self-support---no messenger wire, no grounding on energized power lines; aramid strength members support spans to ~1,500 m depending on loading; OFS PowerGuide DT double-jacket eliminates all gels

Fiber counts from 12 to 864; standard reel lengths 1 km and 2 km; multimode OM3/OM4 available for campus and data center interconnect

Ribbon - High Fiber Count Backbone & Trunk

Fujikura Ribbon Fiber Splicing kit 6-22-26-8089 Medium

 

  • For high-density backbone and trunk, hyperscale data center interconnect, and central office / carrier-hotel cabling

  • Fiber counts from 144 to 6,912+; outside diameter is critical for duct-fill calculations

  • Standard matrix, rollable, and intermittently bonded ribbon (IBR) constructions; rollable / IBR allows higher packing density in a smaller diameter

  • 12-fiber mass-fusion splicing dramatically reduces splice time vs. single-fiber splicing

  • Single jacket, double jacket, armored, or all-dielectric construction

Flat Drop - Last-Mile FTTH

  • Flat self-supporting design for last-mile drops to home or business---aerial self-support or direct-buried final span

  • 1, 2, 4, 6, and 12-fiber counts; G.657.A2 bend-tolerant fiber typical; compatible with standard wedge clamps and closure strain reliefs

  • Toneable (copper toner) variant locates buried drops after install without digging; all-dielectric version also available

  • MDPE outdoor jacket with flame-retardant option for indoor transition; pre-connectorized (OptiTap / hardened) or bulk reel; RUS (RDUS)-listed options available
