FAQs

Q: Does this module require MPO cabling?
A: No. 40GBASE-BiDi uses an LC duplex connection over MMF.

Q: Can I break this module out to 4x10G?
A: No. BiDi uses LC duplex and does not support 4x10G breakout.

Q: What fiber types are recommended?
A: OM3 or OM4 multimode fiber; OM4 provides longer reach.

Q: Is it interoperable with standard 40GBASE-SR4 optics?
A: No. It must link to another 40GBASE-BiDi module.
