SMA Series Fiber Optic Connectors and Adapters

SMA Series Fiber Optic Connectors and Adapters

Threaded metal SMA fiber connectors and adapters for multimode or plastic-fiber assemblies, with selectable ferrule and cable constructions.

Product Features

  • Threaded metal housing for positive engagement.
  • PC-polished ferrule options in several materials.
  • Can be configured for multimode glass fiber or plastic optical fiber.
  • Jacket choices include flame-resistant or LSZH cable constructions where specified.
  • Current table lists at least 500 mating cycles for the ceramic-ferrule version.

SMA Series Fiber Optic Connectors and Adapters use a threaded metal shell for equipment-side fiber connection. The current series supports ceramic, metal or non-metallic ferrule approaches and can be applied to multimode glass fiber or plastic optical fiber, depending on the selected assembly.

SMA fiber interfaces have several construction variants, so the mating receptacle, ferrule bore, fiber type and cable outside diameter must be established before manufacture. Optical performance and mechanical pull values are tied to the actual ferrule and cable design.

Selection & Configuration

Provide the mating SMA interface, fiber material and core size, ferrule construction, cable diameter and finished length. The listed -40°C to 80°C range is associated with the metal-housing configuration; other custom constructions need separate review.

Manufacturing & Customization

Huijue Group can assess OEM SMA assemblies using a customer drawing or mating sample, including cable, ferrule and private-label packaging. Bore size, concentricity, tensile requirement, optical test and tooling feasibility must be confirmed before production.

Information for an Accurate Quotation

  • Mating interface drawing or sample
  • Fiber type and core/cladding size
  • Ferrule material and bore
  • Cable diameter, length and tensile need
  • Test method, packaging and quantity

Installation Notes

Use strain relief appropriate to the selected cable and keep the threaded metal parts and ferrule clean. Do not transfer the listed metal-housing temperature range to a different custom material without validation.

Buyer Questions

Frequently Asked Questions

Answers specific to SMA Series Fiber Optic Connectors and Adapters selection, configuration and purchasing.

Can this SMA connector be used with plastic optical fiber?

Plastic optical fiber is listed as an option, but its fiber size, ferrule bore and termination process must be specified.

Are all SMA fiber connectors optically identical?

No. Ferrule material, bore, fiber type and mating geometry can differ, so a drawing or sample is important for matching an installed port.
