Description

This passive twinax copper breakout cable splits one 100G QSFP28 port into two 50G QSFP28 connections over a 2 metre length. It supports 100GBASE-CR4 and 50GBASE-CR2 and suits short, low-power, low-cost links within or between adjacent racks. It is a cost-effective alternative to optics where one 100G switch port needs to serve two 50G endpoints.

Enquire with XS Network Tech for new or used pricing and availability.

Features

- Hot-pluggable QSFP28 form factor
- Cost-effective alternative to optics for very short 100G to 2x50G links
- Lets one 100G switch port serve two 50G endpoints
- Passive copper design with very low power draw

FAQs

Q: What does this cable connect?
A: It connects one 100G QSFP28 port to two 50G QSFP28 ports, splitting the 100G port into two 50G links.

Q: Is this an active or passive cable?
A: It is a passive twinax copper cable, so it has no active electronics and draws very little power.

Q: What is the maximum length of this cable?
A: The cable is 2 metres long, intended for short links within a rack or between adjacent racks.

Q: Which Ethernet standards does it support?
A: It supports 100GBASE-CR4 on the 100G end and 50GBASE-CR2 on each 50G breakout leg.

Q: When should I choose this over optical transceivers?
A: Choose it for very short runs where lower cost and lower power consumption matter more than reach. Longer distances need optical transceivers or active optical cables.
