FAQs

Q: Do I need a matched transceiver on the far end?
A: Yes. Use BR40D on one side and BR40U on the other to form a bidirectional link.

Q: Is this duplex LC?
A: No. It uses a single LC (LC simplex) and runs both directions over one fiber.

Q: Is this an IEEE 50GBASE-LR optic?
A: No. It is a BiDi (BR40) type. Verify platform support for 50G BiDi optics.

Q: What fiber type is recommended?
A: G.652 single-mode fiber for distances up to 40 km.
