FAQs

Q: Can this cable split a 200G port into four 50G ports?
A: Yes. It provides a CR8 to CR2 electrical breakout from one 200G OSFP to four 50G QSFP56 ports.

Q: What is the cable reach?
A: 3 meters.

Q: Is any power required?
A: No. It is a passive cable and draws no power.

Q: Do the connected devices need to support breakout?
A: Yes. The 200G OSFP port must support 4×50G breakout, and the QSFP ports must support 50G CR2.

Q: Is this suitable for inter-rack runs?
A: It is intended for short-reach in-rack or adjacent-rack connections up to 3 m.
