12dB LC Apc UPC Fixed Optical Attenuator Single Mode Fiber Optic
Attenuator
Product Introduction of Fiber Optic Attenuator:
Fiber optic attenuators are devices that 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.
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.
Features of Fiber Optic Attenuator:
♦ Small bulk and light weight
♦ High stability and reliablity
♦ Precise attenuation values
♦ Low PDL & insertion loss
♦ Precisional reflection polishing
♦ The flexible case for easy portability
♦ Accurate size armed with elegant dust cap, better ensure the
handy installation and protection from out-service.
♦ Durable metal shell for permanent protection
♦ Shaped with metal material, our attenuators perfectly protect the
core insert from external damage.
♦ Accored with the standard of IEC
♦ Low excess loss
♦ High precission of the attenuation
Applications of Fibre Optic Attenuator:
♦ Premise Installations
♦ Wide Area Networks (WANs)
♦ Industrial, Medical & Military
♦ CATV, Metro
♦ Active Device Termination
♦ Optic fiber communication
♦ LAN
♦ Optic fiber CATV

Details of Fiber Optic Attenuator:
Other Types:
Optical fiber attenuators are classified into the following four
types according to the interface:
♦ SC fiber attenuator: applies to the SC fiber interface, which is
similar to the RJ-45 interface, but the SC interface is flatter and
the contact plate inside is a copper column.Fixed the attenuation
power of the optical fiber attenuator is fixed, such as 1dB, 5dB,
or 10dB. For example, the attenuation power of a -3 db optical
fiber attenuator is 3dB. Such fiber attenuators are commonly used
in telecommunications networks, fiber optic test equipment, local
area network (LAN) and cable television (CATV) systems. Fixed fiber
attenuator can be divided into line type and connector type.
♦ LC optical fiber attenuator: Applied to LC optical fiber
interface, can be used to connect SFP module, adopts modular jack
(RJ) latch mechanism, easy to operate, often used in routers;The
connector optical fiber attenuator has the same appearance as the
optical connector. The only difference is that the two ends of the
connector optical fiber attenuator are male connector ports and
female connector ports. The optical fiber attenuator either uses
air gaps to achieve attenuation, or attenuates the optical fiber by
mixing metal ions to achieve attenuation.
♦ FC fiber attenuator: Used for FC fiber interfaces. The outer
layer is wrapped with a metal jacket and fastened by turnbuckle.
Generally used in ODF side, mostly used for distribution frame;The
attenuation power of the adjustable fiber attenuator is not static,
but changes with the change of conditions. The change span is
0.5dB, 20dB, 50dB, etc., and some even reach the accuracy of 0.1dB
and 0.01dB. Tunable fiber attenuators are generally used to
accurately test and measure optical fibers, and are also widely
used in Erbium-doped fiber amplifiers. Their function is to balance
the optical signal power in different channels.
♦ ST fiber attenuator: Applied to the ST fiber interface. It is
usually used on the fiber distribution frame. The enclosure is
round and fastened by turnbuckles.
