Fiber Optic Adapter & Coupler

A fiber optic adapter provides a mechanical interface for joining two connectors, allowing light signals to pass through with high precision. Available in types such as SC, LC, FC, and ST, they support both single-mode and multi-mode fibers, and can be simplex, duplex, or quad. Hybrid adapters (e.g., SC-LC) are also available to connect different connector types.

4. FAQs

• Q1: Are fiber adapters and couplers the same thing?
  Yes, they refer to the same function—connecting two fiber connectors. “Adapter” is more commonly used in fiber network terminology.
• Q2: Can I use a single-mode adapter with multi-mode connectors?
  Technically possible, but not recommended. It may cause performance degradation. Always match fiber types.
• Q3: What’s the benefit of using ceramic sleeves?
  Ceramic sleeves provide better alignment accuracy and lower insertion loss, especially for single-mode connections.
• Q4: Do you offer hybrid adapters?
  Yes, we offer SC-LC, LC-FC, and other hybrid types to interconnect different connector interfaces.
• Q5: How do I choose between simplex and duplex adapters?
  Use simplex for one fiber per connection, duplex for two fibers (usually for TX/RX). Match with your patch cords or connectors.
