Description

This passive twinax direct attach breakout cable connects a 200G QSFP-DD port to two 100G QSFP28 ports over a 1m copper run. It supports 200GBASE-CR8 and 100GBASE-CR4 signalling, making it a cost-effective way to split a single high-density 200G port into two 100G links within the same rack. Suited to short-reach top-of-rack and adjacent-rack connections in data centre switching environments.

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

Features

- Passive twinax copper construction with no active electronics in the cable
- Splits one 200G QSFP-DD port into two independent 100G QSFP28 links
- Short-reach connectivity for in-rack and adjacent-rack deployments
- Direct attach design that avoids the need for separate optical transceivers and fibre

FAQs

Q: What does this cable connect?
A: It connects one 200G QSFP-DD port on one end to two 100G QSFP28 ports on the other end, providing a 200G to 2x100G breakout over a 1m passive twinax cable.

Q: Is this an active or passive cable?
A: It is a passive twinax direct attach cable, so it contains no active signal conditioning electronics and is intended for short-reach links.

Q: What is the cable length?
A: The cable is 1m long, suited to connections within the same rack or between adjacent racks.

Q: Which standards does this breakout cable align with?
A: It is specified for 200GBASE-CR8 on the QSFP-DD side and 100GBASE-CR4 on each of the two QSFP28 breakout legs.

Q: Do I need separate transceivers to use this cable?
A: No. As a direct attach cable it has the connectors integrated at each end, so it plugs directly into compatible QSFP-DD and QSFP28 ports without separate optical transceivers.
