Frequently Asked Questions
What is the primary use of an MPO/MTP loopback plug?
It is used to test the functionality of optical transceivers and network ports by routing the signal from the transmitter back into the receiver, allowing for efficient verification of link integrity.
Can this be used for 100G testing?
Yes, this 12-core loopback is designed for testing high-speed parallel optics, including 40G and 100G transceivers.
Does the APC finish affect compatibility?
Yes, APC (Angled Physical Contact) connectors are required for systems that mandate low back-reflection. Ensure your transceiver or test port is compatible with APC mating.
What does the Type A polarity indicate?
Type A polarity is a standard configuration that maintains fiber mapping throughout the connection, essential for ensuring proper channel alignment in parallel optic systems.
Is the shell durable for field use?
The loopback features a hard-shell casing specifically designed to protect the ferrule and internal fibers, making it suitable for frequent handling in field testing environments.
