Q: What is the difference between 40G LR4 and 40G LR4 PSM? A: Standard LR4 uses one fiber pair (LC) with multiplexed wavelengths. LR4 PSM uses parallel fibers (MPO) to transmit 4 separate signals, allowing for simpler optics and breakout capabilities.

Q: Can I break this out to 4x 10G LR SFP+ modules? A: Yes! Because it is a parallel optic (PSM4), you can use an MPO-to-4xLC Single Mode breakout cable to connect to four individual 10G LR transceivers.

Q: What specific connector does this require? A: It requires an MPO-12 APC (Angled Physical Contact) Single Mode connector. Do not use standard UPC (flat) MPO cables.

Q: What is the maximum reach? A: It supports up to 10km on G.652 Single Mode Fiber.
