Frequently Asked Questions
What is a 40G QSFP+ active optical cable used for?
A 40G QSFP+ active optical cable is used to connect high-speed network switches, routers, and servers in data centers. The breakout design splits one 40 Gbps QSFP+ port into four 10 Gbps SFP+ connections, allowing flexible network segmentation and cost-effective infrastructure scaling without replacing existing SFP+-compatible equipment.
How far can a 15m active optical cable transmit without signal loss?
The 15-meter reach of this AOC breakout cable is specifically engineered to eliminate attenuation and maintain full 40 Gbps throughput across extended distances. Active optical technology compensates for signal degradation, ensuring reliable performance across multi-rack deployments and backbone interconnects where passive copper cables would fail.
Is the ENET QSFP-4X10G-AOC15M-ENC compatible with my existing network equipment?
Yes. This 40G QSFP+ to 4x SFP+ cable is backward compatible with any standard QSFP+ and SFP+ transceiver module. It works with Cisco, Juniper, Arista, Dell, HPE, and other enterprise switches and network adapters that support these connector types, making it a plug-and-play upgrade for existing infrastructure.
What are the power requirements for an active optical cable?
The ENET QSFP-4X10G-AOC15M-ENC draws minimal power (less than 1.5W per channel) directly from the QSFP+ and SFP+ ports, requiring no external power supply. This makes it ideal for dense data center environments where power budgets are critical and simplifies installation logistics.
