SMA905 Fiber Optic Connector Dust Cap Cover
The SMA905 fiber connector cover from JINSHANG TECH prevents contamination and misalignment of open optical ports on equipment and patch cords.
Because the optical path is non-conductive, the SMA905 provides electrical isolation between connected equipment and can be routed past motors, drives and power wiring without picking up noise.
Key Characteristics
- Certified to CE, RoHS,ISO9001
- Insertion loss: 0.2(dB)
- Operating temperature range: -55~80Degree
- IP68 ingress protection for damp or wash-down environments
- Molded to match common TOSLINK/HFBR/POF port profiles
- Prevents accidental misalignment and bending of exposed ferrules
- Keeps connector ferrules and LED/PD ports free of dust and oil
- Reduces field cleaning and intermittent-link failures
Typical Applications
The SMA905 is commonly used for protection of open TOSLINK/HFBR/POF equipment ports, shipping and storage of unterminated patch cords and harnesses, and maintaining clean optical interfaces in industrial cabinets. The result is a reliable, repeatable build that tolerates the routing, vibration and repeated handling typical of production installations.
Frequently Asked Questions
Q: Which connector do these fit? A: Match the cap to the connector profile shown in the specification; common versions cover TOSLINK, HFBR Versatile Link and POF ports.
Q: Do caps replace cleaning? A: No — they prevent contamination, but the end face should still be inspected and cleaned before mating.
Q: Why do optical connectors need dust caps? A: Even a small dust particle on the ferrule can block the light path and raise insertion loss, so open ports should always be capped when not mated.
Q: Are the caps reusable? A: Yes. The caps are designed to be removed and replaced repeatedly during normal service while retaining a snug fit.
