Microduct 7 Way Hexagonal 20/16MM
Microduct 7 Way Hexagonal 20/16MM
High-Performance Ducting System for FTTH & Fiber Networks in KSA & Gulf
Technical Specifications (typical / manufacturer dependent)
Note: Always confirm exact vendor datasheet values for procurement. Below are common values for 7-way 20/16 bundles used across the industry.
Configuration: 7 microducts in hexagonal bundle
Microduct nominal dimension: 20/16 mm (nominal OD 20 mm, nominal ID 16 mm) — varies slightly by vendor.
Material: HDPE (PE100 or equivalent virgin HDPE)
Inner surface: Low-friction silicone or smooth ribbed liner; longitudinal grooves for improved blowing performance.
Outer jacket: HDPE protective outer sheath (color often black with tracer stripes or color coding)
Tracer / locator: Optional integrated 24 AWG tinned copper tracer wire under sheath for locating/grounding.
Operating temperature: Typical −40°C to +60°C (check specific datasheet).
Bend radius: Manufacturer dependent — typical recommended supported bend radius around 30–60× OD (see vendor datasheet).
Pressure rating / mechanical: Designed for direct burial, with crush and loading specifications defined per vendor (consult datasheet).
Standards / compliance: Many vendors align to ISO, TIA, and regional telecom cable installation standards; check vendor certificate.
Weight per meter: Varies by construction; e.g., some microbundle datasheets list weights (e.g., 0.739 lb/ft ~ 1.1 kg/m for certain formats).
How It’s Used — Common Applications in KSA & Gulf
- FTTH Distribution: The installation of microduct bundles is contemplated for new housing subdivisions, gated communities, and clusters of flats. There are seven various ways to distribute to multiple buildings or to increase the capacity for future expansion.
- Air-Blown Fiber Systems: Utilize the low-friction surfaces and the longitudinal grooves to blow either the micro or nano cables over a longer distance without pulling and thus, exposing them to stress. It is the most suitable technique for indoor ducts as well as new construction route spans that are short to medium.
- Direct Burial Trenching: The thick-wall versions can be directly buried without any additional protection for the conduit and hence, helps in cutting down both material and labor costs.
- Data Centers & Campus Backbones: Inside a single trench, provide various logical paths; separate microducts for diversity (primary, backup, dark fiber provisioning) are employed.
- Industrial & Utility Corridors: The suggestion for application in oil/gas, airport, and utility right-of-way installations where multiple segregated fiber paths are needed for the purpose of redundancy is made.
- Blown Fiber Drops and Microduct Branching: The 7-way bundles with the splicing/branching units can be applied together for a fast branching into dwellings or buildings.
Installation & Best Practices (practical, vendor-neutral)
Pre-installation checks
Verify vendor datasheet: dimensions (OD/ID), bend radius, direct burial rating, and tracer conductor presence.
Confirm color coding and labeling plan for each microduct to match network documentation.
Selection of microcable: ensure fiber microcable outer diameter fits comfortably into 16 mm ID and is compatible for blowing or pulling.
Trenching & Receiving
For direct burial: follow local civil and safety codes; ensure bedding, sand cushion and backfill meet vendor and local requirements to avoid sharp stones or point loads.
Protect entry/exit points (handholes/DTs) and install appropriate transition fittings for route changes.
Blowing & Pulling
Use certified blowing equipment (air-blown fiber rigs) and lubricants approved for PE inner liners if needed.
Manufacturer guidance: blowing distances depend on cable design and inner surface grooving — test small runs to determine safe blowing lengths. The FOA notes thick-walled microducts may have limited pull/blow distances relative to thin-wall microducts; plan accordingly.
Bends & Radius
Respect vendor recommended bend radii. Avoid kinking or tight bends which can reduce blowing efficiency and damage the inner liner.
Jointing & Branching
Use purpose-built microduct couplers and branched manifolds for splits. Keep joints smooth and aligned to minimize friction.
Grounding & Locating
If tracer wire included, bond to ground at designated points and use along route for fault locating. If not, plan for marker tapes/locators.
Testing & Documentation
After installation, perform airflow and continuity tests, and record actual blowing distances/air pressures. Maintain route maps mapping each of the 7 ducts with color or numeric IDs.
Advantages — Why choose 7-Way Hexagonal 20/16mm?
- Space-efficient multi-path: Using a single bundle instead of seven individual ducts for seven ducts reduces trench width and therefore saves money.
- Future-proofing: The extra ducts will ensure that the network owners will not have to dig again when they want to augment the capacity.
- Air-blown fiber readiness: The combination of low-friction liners and longitudinal grooves makes blown fiber installations easier, faster, and safer by reducing the risk of microcables being damaged.
- Direct burial robustness: The thick-wall versions provide mechanical protection suitable for direct burial in many places thus reducing the need for extra casing or ducts.
- Traceability: The installation of integrated tracer options leads to a situation where maintenance is made easier and cheaper.
Limitations & Considerations
Blowing distance: Thick-wall direct burial microducts generally achieve shorter blowing/pulling distances than thin-walled microducts; for very long blown runs consider single thin-wall ducts or booster/blow stations.
Bend limitations: Bundled geometry makes tight turns more sensitive; follow manufacturer bend radius guidance.
Vendor variance: Exact OD/ID, wall thickness and tracer designs differ by manufacturer — always verify the datasheet prior to ordering.
Comparative Buying Guide — How to choose the right 7-Way microduct 20/16mm
a. Confirm use case: Direct burial vs inner-duct use vs blown fiber. Direct burial must be thick-wall DB variants. For very long blown runs, consider thin-wall alternatives.
b. Material & grade: PE100 virgin HDPE is suggested, as it has the qualities of a long service life and mechanical robustness, for WL.
c. Inner surface finish: Low friction and longitudinal grooves are helpful for blown fiber distances—please check vendor blow performance data.
d. Tracer & marking: If future locating is an issue, assemblies with either integrated tracer wire or tracer stripe coding should be the ones to choose.
e. Certifications & datasheets: Ask for the manufacturer's test reports on crush resistance, tensile, thermal performance, and bending radius.
f. Spare capacity & layout: Ensure that hexagonal 7-way is the best count—as some projects may prefer 4-way or 12-way bundles according to demand planning.
g. Supply chain & lead time: In Gulf projects, the vendor must confirm that they can provide the necessary reel lengths and perform pre-cutting if required.
Typical Vendor Use Cases & Examples (real world)
Residential FTTH rollouts: Install a single 7-way microbundle down a street; dedicate ducts for initial feed and reserve for future tenants or carriers.
Campus or Industrial Backbone: Use separate microducts inside the bundle for different functional network segments (control systems vs operator communications).
Utility corridors in smart city projects: Deploy one bundle to carry fiber for street lighting, CCTV, traffic signals, and commercial ISPs while preserving future spare ducts.

Maintenance, Repair & Lifecycle
Routine inspection: Check above-ground sections, handholes and vaults for joint integrity and damage after extreme weather or construction activity.
Repair: Use approved couplers and heat/fusion splice techniques for HDPE where manufacturer allows. For small damaged segments, replace jointed lengths rather than splicing mid-run when possible.
Lifecycle planning: HDPE microducts installed correctly can last decades; plan for documentation and mapping so future upgrades can reuse installed ducts rather than re-trench.
Standards & References
Industry guidance commonly referenced for microduct installations includes vendor datasheets (Hexatronic and others) and fiber optic association literature on ducts and microducts. Common points: PE100 HDPE construction, tracer wire options, and direct burial ratings for thick-walled bundles. For example, Hexatronic’s 20/16 mm microduct assembly datasheets and bundled product datasheets capture typical performance and direct-burial recommendations.
Pricing Considerations (Gulf market notes)
- Price is determined by several factors such as the quality of the raw material (PE100), direct underground installation or inner-duct type, inclusion of tracer wire, length of the reel, and supplier brand.
- Acquisition in Saudi Arabia & the Gulf: the entire installation cost (duct + trenching + blowing equipment/time) has to be considered. Microduct bundles usually mean a decrease in total project cost even if their price per unit is a little higher since they allow the trench width to be reduced and at the same time they provide extra capacity.
- Transport & customs: Check the export readiness of the vendor to the GCC market and if the packing of the reel (the weight/size of the reel may have an effect on freight) is suitable. Besides, think about local stocking or distributor relationships as a way of reducing lead time.
