FAQs

Q: Can this cable break out a 40G QSFP LR4 to four 10G ports?
A: No. LR4 uses duplex LC. Breakout requires parallel single‑mode (PSM) optics on the QSFP side.

Q: Is polarity or MPO gender important?
A: Yes. Ensure the MPO polarity and pinning (male/female) match your transceivers or cassettes.

Q: Does this support 1310 nm operation?
A: Yes. OS2 single‑mode supports 1310 nm and 1550 nm applications.
