Q
What types of Cisco Catalyst cables are available?
A
Cisco Catalyst cables include Direct Attach Copper (DAC) cables for short-reach, Active Optical Cables (AOC) for medium-reach, and fiber optic patch cables (multimode and singlemode) for long-reach applications.
Q
How do I choose the right Cisco Catalyst cable for my switch?
A
Select a cable based on required data rate, distance, interface type and budget: use DAC for high-speed links under 7 m, AOC for distances up to 100 m (multimode) or 10 km (singlemode), and fiber patch cables for extended reach.
Q
Are Cisco Catalyst cables compatible with third-party devices?
A
Cisco Catalyst cables are qualified and tested on Cisco platforms. Third-party compatibility is not guaranteed and may impact performance or support; Cisco-certified cables ensure optimal interoperability.
Q
What is the maximum length supported by Cisco Catalyst copper cables?
A
Cisco Direct Attach Copper (DAC) cables support up to 7 meters. For longer distances, use Active Optical Cables (AOC) or fiber optic patch cables.
Q
What transmission speeds do Cisco Catalyst cables support?
A
Cisco Catalyst cables support speeds from 1 Gbps to 100 Gbps, including 10G, 25G, 40G and 100G links, depending on cable type and transceiver compatibility.
Q
What is the difference between Cisco Catalyst copper and fiber optic cables?
A
Copper cables (DAC) provide low-latency, short-reach connectivity under 7 m. Fiber cables (AOC or patch) support longer distances (100 m multimode, up to 10 km singlemode) and higher EMI immunity.
Q
Can I use Cisco Catalyst cables for Power over Ethernet (PoE) applications?
A
Only Cisco Catalyst Cat6a or higher copper patch cables are rated for PoE up to 90 W. DAC and AOC cables are not designed or certified for PoE power delivery.
Q
How do I install Cisco Catalyst cables properly?
A
Maintain recommended bend radius, avoid kinks, secure cables with proper clips, route separately from power lines, and fully insert connectors until they click to ensure reliable links.
Q
How do I troubleshoot connectivity issues with Cisco Catalyst cables?
A
Verify link lights, run the switch’s built-in cable diagnostic, inspect connectors for damage, test with a known-good cable, and confirm interface speed and duplex settings.
Q
Do Cisco Catalyst cables come with a warranty?
A
Yes. Cisco Catalyst cables carry Cisco’s limited lifetime warranty, covering defects in materials and workmanship when used with supported Cisco equipment.
Q
How can I order replacement Cisco Catalyst cables?
A
Order using the Cisco part number through Cisco’s online store or an authorized Cisco partner. Verify compatibility via Cisco’s website or product datasheets.
Q
What industry standards do Cisco Catalyst cables comply with?
A
Cisco Catalyst cables meet IEEE 802.3 Ethernet, TIA/EIA-568 structured cabling and SFF multi-source form-factor standards for guaranteed performance and interoperability.
Q
How do I maintain and clean Cisco Catalyst cables?
A
Keep dust caps on unused ports, clean optical endfaces with approved swabs or cleaners, avoid excessive flexing, and store cables in a clean, dry environment.
Q
Are Cisco Catalyst cables pre-terminated for rack deployment?
A
Yes. Cisco Catalyst patch cables and DAC/AOC assemblies are factory-terminated, labeled and tested for plug-and-play installation in racks and data centers.
Q
What environmental conditions can Cisco Catalyst cables withstand?
A
Cisco Catalyst cables operate from 0 °C to 70 °C with non-condensing humidity. Specific ratings (CM, LSZH, plenum) vary by cable model, as detailed in product specs.
Q
Where can I find detailed Cisco Catalyst cable specifications?
A
Detailed specifications are available in the Cisco Catalyst Cable Release Notes and Data Sheets on Cisco’s official website under the Documentation section.
