Direct Attach Copper (DAC) Cable SIGNAMAX 100-35C-1M 10G 1 m, Cisco compatible

SIGNAMAX 100-35C-1M is a 1 m passive Direct Attach Copper (DAC) cable that delivers 10G Ethernet connectivity and is compatible with Cisco equipment. Designed for short-distance interconnects, this cable connects switches, routers and servers without separate optical transceivers, providing a compact, low-latency physical link for top-of-rack and intra-rack deployments in data centers and server rooms.

Advantages

The passive DAC construction offers a cost-effective solution for 10G links over short distances while reducing power consumption compared with active optics. Compatibility with Cisco equipment simplifies integration into existing network environments and eliminates the need to stock separate transceivers. The fixed 1 m length minimizes cable slack and helps maintain tidy cable management in dense rack environments.

Suitable for

• Top-of-rack and intra-rack switch-to-switch connections
• Server-to-switch links within the same rack or adjacent racks
• Short-distance connections in data centers and server rooms

Key specifications

• Connector type: SFP+ compatible direct-attach copper
• Length: 1 meter
• Data rate: 10 Gbps
• Cable type: Passive copper twinax assembly
• Typical use: Short-reach rack-level interconnects

How to use

Insert each SFP+ form-factor connector into the corresponding SFP+ ports on the devices to be linked, ensuring correct orientation and secure latching. No additional configuration is required on most devices; the link should negotiate at 10G where the network equipment supports the standard SFP+ copper interface. Route the cable to avoid tight bends and excessive strain on the connectors, and organize the cable within the rack to maintain airflow and accessibility.

Usage recommendations

Use the 1 m passive DAC for connections within the same rack or between adjacent racks. Verify Cisco compatibility and firmware or vendor restrictions in device documentation before deployment. Avoid running the cable near strong electromagnetic sources and follow data center cable management best practices to prevent connector damage.
