FAQs

Q: Can this module establish a bidirectional 40G link by itself?
A: No. It is receiver-only and must be paired with a compatible BiDi transmitter at the far end.

Q: Does it use LC or MPO cabling?
A: LC duplex. BiDi enables 40G over a single LC duplex MMF pair.

Q: Is single-mode fiber supported?
A: No. This BiDi receiver is specified for OM3/OM4 multimode fiber.

Q: Will it work in any QSFP+ 40G port?
A: It requires a QSFP+ port that accepts 40G BiDi optics and your application must support an Rx-only device.
