F-SMA
INTRODUCTION
F-SMA is one of the first generations of fiber optic connectors. Established
as a standard in the industry, it is now used in many applications, such
as industrial and medical, in which the connector can be adapted with
a large range of MultiMode fibers.
They are designed for systems requiring reliable performances over short
and medium ranges.
BENEFITS & FEATURES
• Easy to use connector
- Screw coupling nut
- Metal body with cylindrical alignment and accurate air gap
• Flexible
- Metal or ceramic optical ferrule allowing different fiber diameters
- Two series available: F-SMA 5 (straight barrel) and F-SMA 6 (step down barrel) to adapt to customer need
- Cable range: 0.9 mm, 2 mm and 3 mm
- Compliant with IEC 61754-22 and MIL-C-83522

CONNECTORS
F-SMA connectors are available in 2 different ended shapes: F-SMA 5 and F-SMA 6:
F-SMA 5 Straight barrel (F707)
F-SMA 6 Step-down barrel (F708)
Each F-SMA 6 connector is delivered with two plastic alignment sleeves.
•
HALF LENGTH alignment sleeve:
in order to precisely align a F-SMA 6 in a receptacle device.
Application: Slide the sleeve over the barrel of the F.-SMA 6 connector up to its shoulder, before fitting the connector
into the receptacle.
•
FULL LENGTH alignment sleeve:
in order to optimize the alignment of two F-SMA 6 connectors in an F-SMA adapter.
Application: Slide the alignment sleeve over one of the F-SMA 6 connectors before inserting them in the adapter.
Knowing that when unmated, the alignment sleeve will remain on the connector fitted at end 2
