A fiber optic adapter is a device that connects fiber optic connectors, minimizing optical link loss so that the light energy emitted by the transmitting fiber can be coupled to the receiving fiber to the maximum extent. The SC adapter provided by SUNET offers easy installation, low insertion loss, good interchangeability and resistance to high and low temperatures, and is widely used in telecommunication networks, CATV, FTTX and other fields.

Frequently Asked Questions
Q: What types of adapters are available?
A: SC, LC, FC and ST adapters in simplex or duplex versions, with UPC/APC polish, for single-mode and multi-mode fiber.
Q: What is the difference between UPC and APC adapters?
A: The internal sleeve geometry matches the ferrule polish: APC adapters (green) are for APC connectors and UPC adapters (blue) for UPC connectors. Never mix them, as mismatching causes high insertion loss and back reflection.
Q: What material is the alignment sleeve?
A: High-precision zirconia ceramic sleeves are used for stable alignment, low insertion loss (typically 0.2dB or less) and long mating cycles.
Q: What is the MOQ?
A: The MOQ is low for standard items; please check with our sales team for your specific quantity and configuration.
