A fiber optic adapter, sometimes also called a coupler, is a small device designed to terminate or link fiber optic cables or fiber optic connectors between two fiber optic lines.
By precisely linking two connectors, fiber optic adapters transmit the light source with minimal loss and reduce losses as much as possible. At the same time, fiber optic adapters feature low insertion loss, good interchangeability and repeatability. We supply a wide range of adapters and hybrid adapters, including male-to-female hybrid fiber optic adapters.
Application
1. Widely used in FTTH access networks 2. Telecommunication networks 3. CATV networks, data communication networks 4. Local area networks
Features
High loss performance, low insertion loss.
Split zirconia (ceramic) ferrule is adopted.
Usually mounted in a distribution panel or wall box.
The adapter is available for all standards.
Adapters are color-coded for easy identification of the adapter type.
Available with single-core and multi-core patch cords and pigtails.

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.
