FAQs

Q: Is this compatible with SWDM4 or SR4 modules?
A: No. It must connect to another SR BD/BiDi transceiver.

Q: What cabling is required?
A: OM3/OM4 multimode fiber with LC-duplex connectors.

Q: When should I choose SR BD over SWDM4?
A: Choose SR BD when you want 100G over LC-duplex MMF with simple bidirectional operation and the specified reaches.

Q: Does it support breakout to 4x25G?
A: No. BiDi optics do not support 4x25G optical breakout.
