Q: Is this 400G SR8 transceiver compatible with existing multimode fiber? A: Yes, it works with OM3 and OM4 cabling, but OM4/OM5 is recommended for full 100m reach.

Q: What connector type does it use? A: It uses an MPO-16 (or MPO-24) connector to support 16 fibers (8 transmit, 8 receive).

Q: Can it break out to 50G SFP56? A: Yes, it supports 8x 50G PAM4 breakout mode for high-density server connections.

Q: Is it backward compatible with 200G SR8? A: It depends on the switch capabilities, but physically it fits the same QSFP-DD port.
