Fiber Closures & Cabinets
Closures, cabinets, and housings protect and organize fiber at every access point in the network, from the splice closure in the vault, to the distribution cabinet on the pad, to the network interface device (NID) at the subscriber premises. Splice closures fall into two primary families: Aerial, strand-mount, and underground or direct-buried, each engineered for very different environmental loads. Correct specification at the design stage ensures the network can scale with subscriber take-rate over time.
Galloway stocks closures across both families along with outside-plant cabinets and subscriber housings, from the manufacturers specified on FTTX projects across broadband, telecom, and utility markets: CommScope (including the widely specified FOSC series), AFL, Prysmian, OFS, PLP, and Channell
Loose Tube - OSP Backbone, Feeder & Distribution
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
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

Ribbon - High Fiber Count Backbone & Trunk
-
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
Aerial / Strand-Mount Splice Closures
-
Attaches to messenger wire or lashed cable on pole lines; engineered to survive UV, freeze-thaw cycling, ice loading, high heat, and prolonged humidity exposure
-
Modern gel-sealed and heat-shrink sealing systems maintain environmental integrity across decades of thermal cycling — no gasket degradation over time
-
Re-enterable designs allow technicians to open, re-splice, add fiber, and reseal multiple times without compromising seal quality
-
Internal splice tray systems organize individual splices, hold splice protectors, and route fiber with consistent bend radius control
-
Scalable internal configurations support fiber count expansion — from a 48-fiber feeder run today to a 144-fiber upgrade tomorrow — without replacing the housing
-
Messenger-mount hardware (bracket, clamp, and bail-wrap configurations) sized to match cable diameter and messenger gauge
-
NEMA, IP, and GR-771 rated options available for demanding environments including coastal, high-humidity, and extreme-temperature installations
-
Available from CommScope, AFL, Prysmian, OFS, and Preformed Line Products
Underground & Direct-Buried Splice Closures
-
Dome configurations seal against a base plate with perimeter cable entries for branch splices; inline configurations handle through-cable splicing in conduit runs
-
Gel-sealed systems flow into voids around cable jackets, maintain elasticity across temperature extremes, and resist hydrostatic pressure in fully flooded handholes and vaults
-
Engineered cable entry kits — grommets, gel blocks, and compression fittings — seal tightly around varying cable diameters and hold that seal through thermal expansion and soil movement
-
Armored cable compatible: entry systems and internal grounding provisions handle both corrugated steel tape and wire armor continuity requirements
-
Direct-burial rated options with depth ratings for no-conduit installations; vault and handhole configurations for technician-accessible splice points requiring future re-entry
-
Designed for the conditions aerial closures never face: hydrostatic pressure, groundwater intrusion, soil movement, and mechanical impact from excavation equipment
-
Re-enterable modular designs available for rapid-deployment and overbuilder applications requiring field flexibility
-
Available from CommScope, AFL, Prysmian, and Clearfield
Outside-Plant Street & Distribution Cabinets
-
Pad- and pole-mount cabinets that house splice points, optical splitters, and connectorized distribution at the edge of the outside plant
-
Lockable, weather-rated enclosures sized to distribution port count and splitter configuration
-
Configurations to suit feeder-to-distribution transitions on FTTX builds (manufacturers pending verification---see notes)
Network Interface Devices (NID) & MDU Terminals
-
Single-subscriber NIDs for FTTX/FTTH drop termination at the subscriber premises
-
MDU terminals in 4, 8, 12, and 24-port configurations for apartment buildings and commercial properties
-
Indoor and outdoor-rated enclosures; SC and LC adapter configurations
-
Lockable weatherproof construction for outdoor pedestal or wall-mount installations
Fiber Distribution Hub PON Cabinets
