Cisco QSFP-100G-CU1M Active Optical Cable – Full Product Guide
The Cisco QSFP‑100G‑CU1M Active Optical Cable (AOC) is a high-speed 100 Gbps interconnect solution designed for short-distance data center and enterprise connections. Unlike traditional transceivers with separate fiber modules, this is a pre-terminated, all-in-one active optical cable using QSFP28 connectors at both ends, providing plug-and-play 100G connectivity.
The cable supports 100GBASE-CR4 / 100G Ethernet and delivers low latency, high signal integrity, and power-efficient performance. With a 1-meter length, it is ideal for switch-to-switch, server-to-switch, or switch-to-router connections inside racks or across adjacent racks in data centers. The cable is hot-pluggable and supports Digital Diagnostic Monitoring (DDM/DOM) for real-time monitoring of voltage, temperature, transmit power, and receive power.
Key Features
- 100Gbps data rate for high-performance short-distance links
- QSFP28 form factor connectors on both ends
- 1-meter active optical cable (AOC) for plug-and-play connectivity
- Low power consumption (~2.5W typical)
- Hot-swappable design for easy installation
- Supports Digital Diagnostic Monitoring (DDM/DOM)
- Low latency, high signal integrity suitable for data center environments
- Compliant with IEEE 802.3bm 100GBASE-CR4 standard
How to Install the Cable
1. Check Compatibility
- Ensure both devices have QSFP28 100G ports that support AOC connections.
2. Remove Protective Caps
- Remove dust caps from both QSFP28 connectors on the cable.
3. Insert the Cable
- Carefully plug each end into the corresponding QSFP28 ports until it clicks.
4. Verify Detection
- Use the CLI on either connected device to check cable detection: show interface transceiver details
5. Confirm Link Status
- Check that the interface is active: show interface status
If the port status is up/up, the cable is working correctly.
Compatibility
The Cisco QSFP-100G-CU1M AOC is compatible with Cisco devices that have QSFP28 ports, including:
- Cisco Catalyst 9300 / 9400 / 9500 / 9600 Series Switches
- Cisco Nexus 3000 / 9000 Series Switches
- Cisco ASR aggregation routers supporting QSFP28 ports
It can also work with other QSFP28-compliant devices, but always check vendor interoperability.
Applications
- Short-distance data center interconnects (within racks or between adjacent racks)
- Server-to-switch connections
- Switch-to-switch connections in high-density environments
- High-performance computing (HPC) clusters
- Enterprise backbone connections
- AOCs are ideal when short-reach, high-bandwidth, low-latency, and plug-and-play deployment is needed.
Frequently Asked Questions (FAQ)
1. What is Cisco QSFP-100G-CU1M?
It is a 1-meter Active Optical Cable (AOC) with QSFP28 connectors, delivering 100 Gbps connectivity for short-distance links.
2. What is the maximum distance?
The standard length is 1 meter, designed for intra-rack or adjacent-rack connections.
