Frequently Asked Questions
What does the 12dB value mean?
It indicates the fixed amount of optical signal reduction provided by the attenuator, essential for preventing receiver saturation in high-power systems.
Is this compatible with both 1310nm and 1550nm?
Yes, this attenuator is specifically designed for dual-wavelength usage at both 1310 nm and 1550 nm.
What type of connector does this use?
This is an ST-style connector with a UPC (Ultra Physical Contact) polish.
Can I use this for multi-mode fiber?
No, this model is designed strictly for single-mode fiber applications.
What is the return loss specification?
The unit maintains a return loss of greater than 55 dB, which ensures minimal signal reflection.
