FAQ
- Q: What is the difference between Wide Key and Narrow Key?
- A: Wide Key (N-type) and Narrow Key (R-type) refer to the key width of the FC connector. They are not interchangeable, so please confirm your connector type before ordering.
- Q: Can this type of adapter achieve 0.05 dB insertion loss?
- A: According to Seikoh Giken’s official specifications, no lower insertion loss values (such as 0.05 dB) are specified for this model, and such values are typically not guaranteed in practical applications.
- Q: Can this adapter be used with single-mode and multimode fibers?
- A: This adapter is designed for single-mode fiber (SMF) applications. It is not recommended for multimode systems.
- Q: How can I ensure low insertion loss during use?
- A: To ensure low insertion loss, clean the connectors before mating, avoid unnecessary repeated connections, use high-quality connectors, and ensure the correct key type is properly matched.
