- Singlemode Attenuator
SGA-series attenuator is a simple design that will fit onto
existing 3mm jacketed fiber. This
3-loop design allows the user to adjust attenuation
adding or removing fiber from each loop. Loop attenuation
is based on controlling the diameter of the bend in the fiber.
The controlled bend adds no reflections, will not harm the
fiber and is reusable.
Step 1-6dB @ 1310 Singlemode 3mm Fiber
Step 5-15dB @ 1310 Singlemode 3mm Fiber
Step 5-25dB @ 1310 Singlemode 3mm Fiber
Attenuation values are based on 1310 nanometer singlemode
operation using 3mm jumper cord with Corning SMF-28 fiber.
Other cords (i.e. smaller diameter outer jackets) or other
glass manufacturers may exhibit different attenuation levels.
AT&T depressed clad fiber exhibits approximately 1/4 of the
attenuation of Corning SMF - 28.
