Fiber Optic Attenuator Sc Apc SM Simplex 2.0mm 5db Fibre Optic Sc
Attenuator
Description
Fiber optic attenuators are devices which reduce (attenuate) the
strength of a fiber optic signal within a fiber optic network.
Attenuators are usually used when the signal arriving at the
receiver is too strong and hence may overpower the receiving
elements. This may occur because of a mismatch between the
transmitters/receivers (transceivers, media converters), or because
the media converters are designed for a much longer distance than
for which they are being used. Sometimes attenuators are also used
for stress testing a network link by incrementally reducing the
signal strength (increasing the dB attenuation) until the optical
link fails, thus determining the signal's existing safety margin.
Our attenuators are a very high quality design using doped fiber to
attenuate the signal. Our singlemode attenuators offer a operating
wavelength range of 1250nm to 1600nm, covering both the common
1310nm and 1550nm operating wavelengths.
Maximum transmission power is typically one watt. We stock
attenuators for the following fiber optic connector types: ST, SC,
SC/APC, FC, FC/APC, LC, LC/APC, MU. Other connector type
attenuators are available upon special order. We stock most values
between 1dB and 25dB for each of these attenuator types.
Although fiber optic attenuators are normally used in singlemode
circuits, because this is where the stronger lasers are used for
distance transmission, we also have multimode attenuators available
(upon special order) in 50/125 and 62.5/125 fiber sizes. Since
these will be custom made, minimum order quantity (50+) and
extended lead time (2-4 weeks) may be required.
