What is a fiber optic adapter and what does the colour indicate?

A fibre optic adapter is used to join two optical connectors by aligning the fibres present in the adapter and/or connector. Each end of an adapter can be either male or female.

Female adapters normally face the connectors and align their fibres, so they are not normally specific to a particular polish, but the user can decide the type of polish that connects the ends. The colour of a female adapter does not require the use of a specific fibre type and polish, but it is advisable to respect it to easily identify the type of fibre connected.

The male adapters include a ceramic or plastic ferrule that protects and aligns the fibre as it is inserted into the female end. This ferrule is polished and the user should ensure that the polish on the other end is compatible. The colour of a male adapter identifies the type of fibre and polish.

To ensure a link with the lowest possible light loss, it is imperative that the two fibres that are connected to the adapter have a compatible polish:

  • The APC (Angle Physical Contact) polish has an 8° angle cut, and is only compatible with other APC polishes.
  • The PC (Physical contact) polish has a convex cut, and is compatible with other convex polishes, such as PC and also UPC.
  • The UPC (Ultra Physical contact) polish has a convex cut, thinner than PC, and is therefore compatible with both PC and UPC polishes.

The colour of the adapter helps to identify at a glance the type of fibre and the polish of the connected fibre, and manufacturers usually follow the following recommendations:

  • Green: Single-mode (SM) fibres with APC polish.
  • Blue:Single-mode (SM) fibres with PC or UPC polishing.
  • Beige: multimode (MM) fibres, no polish identified.

At Televés we follow this recommendation to facilitate the installation and maintenance of fibre networks and to avoid possible confusion in the connectorisation.
