The DIMI Aerial Drop Cable Clamp is designed to anchor and tension fiber optic drop cables in overhead FTTH and FTTx access networks. It secures flat or round drop cables between poles, support hardware, and subscriber premises while maintaining controlled cable retention during installation and outdoor service.

Mechanical Design & Cable Compatibility
The clamp uses a self-locking wedge or gripping mechanism to secure the drop cable under aerial tension. The gripping force increases as the cable is loaded, helping prevent cable slippage during installation and normal outdoor service.
The cable-contact surfaces are shaped to distribute holding pressure along the jacket rather than concentrating force at a single point. This design is particularly important for FTTH drop cables with relatively thin outer sheaths.
Compatibility should be evaluated according to the cable's cross-sectional profile, jacket construction, tensile member arrangement, and required installation load. The clamp configuration can be selected for flat or round cable constructions, while the specified cable dimensions and MBL in the Technical Specifications define the applicable range.
Applications
FTTH / FTTx aerial drop cable anchoring
Pole-to-premises subscriber connections
Building façade and wall-mounted drop cable routes
Residential and commercial broadband access networks
Rural and suburban last-mile fiber deployment
New aerial network construction and network maintenance or replacement
Installation Method
The clamp is intended for simple field installation with minimal tooling.
- The clamp is intended for simple field installation with minimal tooling.
- Insert the drop cable into the clamp body or gripping wedge.
- Pull the cable to the required position and allow the gripping mechanism to lock onto the jacket.
- Check that the cable is fully seated and that the required slack or tension is maintained.
- Verify that the cable is not excessively bent, crushed, or subjected to unintended point loading.
Customization / OEM
DIMI can supply the clamp in configurations matched to the buyer's cable and installation hardware, including:
- Flat or round cable compatibility
- Cable diameter or cross-section adjustments
- Different hook, bail, loop, or eye configurations
- Standard or reinforced mechanical versions
- Polymer color customization
- Logo marking or product identification
- Customized packaging and labeling
For OEM projects, buyers should provide the cable dimensions, required MBL, mounting hardware, installation environment, and packaging requirements. These parameters allow the clamp geometry and material combination to be matched to the actual network application.
Inspection & Testing
Dimensional inspection
Cable-contact dimensions, hook/bail geometry, and critical assembly dimensions.
Material inspection
Verification of polymer and metal material specifications.
Mechanical tensile test
Verification of the clamp's specified minimum breaking load.
Grip/slippage inspection
Confirmation that the cable remains securely retained under the specified load.
Visual inspection
Checking molding quality, metal surface condition, burrs, cracks, deformation, and assembly defects.
Corrosion-protection inspection
Verification of stainless-steel or galvanized components according to the specified material and finish.
Frequently Asked Questions
Q: Can I order samples before placing a bulk order?
A: Yes. Samples can be provided for cable compatibility, installation, and mechanical evaluation before bulk production. Sample quantity and shipping arrangements can be confirmed according to the project requirements.
Q: How are aerial drop cable clamps packaged for export?
A: Standard export packaging should protect the clamps from deformation, moisture, contamination, and surface damage during transportation. Bulk quantities are normally packed in cartons, with inner bags or separators used when required by the product configuration.
Q: What documents can be supplied with an order?
A: Typical commercial documentation includes the commercial invoice, packing list, and certificate of origin where required. Product inspection reports, material documentation, or other project-specific documents can be arranged when specified in the purchase order.
Q: What is the typical MOQ for standard orders?
A: A practical MOQ is 500 pieces for standard commercial orders. OEM configurations, special packaging, or customized tooling may require a different MOQ, which should be confirmed before quotation.
Q: What payment terms are available?
A: Standard payment terms can be T/T, with a typical arrangement of 30% deposit and 70% balance before shipment. L/C can also be considered for qualified commercial orders.
Q: What is the typical lead time for bulk orders?
A: For standard orders, the typical processing time is 7–14 days, followed by approximately 20–30 days for shipping, depending on the destination and selected shipping method. Customized orders are scheduled separately after specification confirmation.
