Amphenol 905 & 906 SMA Connectors
Amphenol Fiber Optics was a pioneer in developing the first industry standard fiber optic
interconnect system by introducing the SMA connector. The 905 and 906 series were the first
fiber optic interconnect system to gain industry wide acceptance for military, industrial, data
communications and medical applications, before fiber was ever used for telephony.
Today, Amphenol Fiber Optics continues to support these markets with a wide variety of
products that meet the continuing need for the family of SMAs. The SMA connector family
utilizes a threaded coupling nut system for mating and de-mating. Available with zirconia or
stainless steel ferrules with custom hole sizes, the SMA is an excellent choice for a robust, lowcost and reliable system.
Unlike any other connector on the market and as shown on page B-4 of this section, the SMA
has a wide range of accessories such as adapters, receptacles, boots, etc. that make it the
perfect choice for any sort of experimental or R&D type application. FOC stocks many of these
items and can assistant your design.

Amphenol High Power SMA Connectors
High-Power Delivery can cause many problems not found in standard fiber applications. A
large amount of heat can be generated if any defects, debri or adhesive happens to get in
the path of the light and this heat can cause sever damage the connector, fiber and
equipment it is plugged into. To address these problems, Amphenol has developed the
following options for their line of High Power 905 SMA Connectors.
Damage Resistant - The inner tip of the ferrule is recessed creating a “well” so that nothing
makes direct contact with the tip of the fiber.
Fiber Grip - A fiber retention system that eliminates the need for epoxies at the fiber/
connector end face. This option also allows the connector to be installed and removed any
number of times for re-works and repairs.
Beryllium Copper (BrCu) - The standard ferrule is produced from high grade type 303 stainless
steel but the damage resistant ferrule is also available in BrCu. BrCu conducts heat very well
and acts as a heat sink to aid in the dissipation of heat generated at the fiber end face.
