Product Q&A

Q:What is the main function of this MPO loopback attenuator?

It is mainly used to reduce the optical signal power of fiber links, prevent overload damage of photodetectors and optical receivers caused by excessive optical power, and realize multi-channel optical link closed-loop testing, suitable for debugging and maintenance of 40G/100G high-speed networks, FTTH and 3G/4G wireless networks.

Q:Which attenuation levels and end face types are supported?

Optional attenuation levels: 3dB, 5dB, 10dB, 15dB; MPO/MTP-UPC and MPO/MTP-APC dual end faces are available, compatible with 850nm, 1310nm, 1550nm full communication wavelengths and full series of single-mode and multimode fibers.

Q:How many cores of optical fibers does it support and which connectors are supported?

It supports 12F/16F/24F/32F multi-core ferrules, compatible with standard and elite low-loss MTP/MPO connectors with optional male and female connectors, perfectly matching QSFP high-speed optical modules.
