BlueLAN Cable breakout Direct Attach pasivo QSFP 40GBASE-CR4 a 4x10GBASE-CR SFP+, 2 m, AWG30 (compatible con Dell GZH8C42) GZH8C42-BL

Data center technicians connecting a Dell switch with a 40G QSFP port to four servers with 10G SFP+ ports can rely on this BlueLAN breakout cable. It splits a single 40G QSFP connection into four independent 10G SFP+ links, eliminating the need for separate transceivers and reducing cable clutter.

Key specifications

• Connector A: QSFP (40G)
• Connector B: 4x SFP+ (10G each)
• Cable type: Passive copper twinax
• Length: 2 meters
• Wire gauge: AWG30
• Compliance: IEEE 802.3bj (40GBASE-CR4), IEEE 802.3ae (10GBASE-CR)
• Hot-pluggable: Yes

Why choose it

This passive DAC cable delivers low-latency, low-power connectivity for short-reach links. It is a cost-effective alternative to optical transceivers and fiber cabling, ideal for top-of-rack switching and server aggregation.

Ideal use cases

• Connecting a 40G QSFP switch port to four 10G SFP+ server NICs
• High-density data center rack cabling
• Short-distance network aggregation

Good to know

The cable is compatible with Dell equipment using the GZH8C42 part number. Passive design means no signal regeneration, so it is best suited for distances up to 5 meters. The 30 AWG wire provides flexibility for tight rack installations.
