Description
The FiberMania LC Plug-in Fixed Attenuator (Multimode, 5dB) is designed to reduce optical signal levels in multimode fiber networks, helping protect receivers, balance optical channels, and ensure accurate link performance. Using an LC male-to-female plug-in design, it installs directly into patch panels, test equipment, or LC adapters without requiring additional tools or installations.
This 5dB LC attenuator supports 850nm and 1300nm multimode wavelengths, delivering stable attenuation with high accuracy and low back reflection. Built with rugged, compact housing and manufactured to Telcordia standards, it is suitable for telecom operators, data centers, CATV networks, and laboratory testing environments.

Frequently Asked Questions (FAQ)
Q: Can this 5dB attenuator be used with single-mode LC connectors?
A: It is optimized for multimode, but LC connectors are physically compatible. However, single-mode applications should use an SM-rated attenuator for best performance.
Q: Can I choose a different attenuation value?
A: Yes. FiberMania can supply fixed attenuators from 1dB to 30dB on request.
Q: Does this attenuator cause significant insertion loss outside the 5dB value?
A: No. The attenuator is designed for precise attenuation and low excess insertion loss.
Q: Are dust caps included?
A: Yes, each attenuator is shipped with protective caps.
Q: Can this be used for testing 40G/100G multimode equipment?
A: Yes, as long as the equipment supports LC multimode connections at 850/1300nm.
