FC Attenuator XXDB
(100FBCXXX) |
| |
Description:
Mechanical optical attenuator is a passive optical attenuator. The shape of the mechanical attenuator is just like the fiber adaptor. It can be applied in traditional optical network, optical testing project, FTTx construction and etc which the optical power may be over the limit of the equipment. The bulkhead mechanical attenuator allows the interconnection of two patchcords. Female to male mechanical attenuator is assembled with a fixed type connector,so it can only be connected with one patchcord. Both fixed value and variable value attenuator is available.

>>Application : |
|
| |
When a fiber device is very close to another one—for example, as little as 3 feet (0.9 m)—the signal is extremely strong. The light signal doesn't have time to attenuate or lose strength as it travels down the fiber. This is called receive saturation. The energy level of the fiber optic signal is too high and exceeds the operating range of the receiving equipment. So when the optical signal reaches the other end, it reflects back along the cable. This reflection distorts the signal and disrupts data.To solve the problem, an attenuator is necessary. They feature guaranteed return-loss measures to attenuate the signal. To achieve the fixed return loss, the attenuators use a doped single-mode fiber with a wavelength of 1310–1550 nm.Use the attenuators in CATV, LAN, WAN, and telecommunications applications. When you have multiple fiber runs, use the attenuators to make sure all are operating at the same optical level. You can also use the attenuators as part of your test kits to verify optical levels. |
