Frequently Asked Questions
What is the purpose of an LC APC fiber attenuator?
It is used to reduce the optical power of a signal, preventing the receiver from being overloaded or saturated, which could otherwise cause bit errors in the network.
Does this attenuator support 1310nm and 1550nm?
Yes, this model is designed for dual-wavelength operation, covering both standard telecom windows.
Is this a fixed or variable attenuator?
This is a fixed connector-type (build-out) attenuator with a set value of 4 dB.
What does the >65 dB return loss rating mean?
It indicates that the attenuator reflects very little light back toward the source, which is critical for maintaining signal integrity in APC-based systems.
Can I use this in an LC UPC port?
No. This attenuator features an APC (Angled Physical Contact) connector, which is physically and optically incompatible with standard flat UPC connectors.
