Questions & Answers
What is the QSFP-H40G-AOC20M= cable and its primary application?
The QSFP-H40G-AOC20M= is a 20-meter 40GBASE active optical cable designed for high-speed server, switch and storage interconnects in data center environments.
What data rate does the QSFP-H40G-AOC20M= support?
This AOC supports a full duplex data rate of 40 Gbps, delivering four independent 10 Gbps channels aggregated over a single QSFP connector.
What is the maximum reach of the 20M 40GBASE AOC?
The cable provides reliable 40 Gbps connectivity up to 20 meters in standard data center conditions without signal degradation.
Which connector type is used on the QSFP-H40G-AOC20M=?
It features industry-standard QSFP+ (Quad SFP+) connectors on both ends for plug-and-play compatibility with QSFP+ ports.
Is the QSFP-H40G-AOC20M= hot-pluggable?
Yes. The QSFP-H40G-AOC20M= supports hot-plug insertion and removal without powering down the host device or compromising data integrity.
Which vendors and platforms is this cable compatible with?
This AOC is fully compatible with all servers, switches and routers that accept MSA-compliant QSFP+ modules, including Cisco, Juniper, Arista and HPE.
What environments are ideal for deploying the 20M 40GBASE active optical cable?
It is optimized for high-density, short-reach interconnects in hyperscale and enterprise data centers, cloud fabrics and HPC clusters.
How do I install the QSFP-H40G-AOC20M=?
Align the QSFP+ connector key with the port slot, insert firmly until the latch engages, and verify link status via LED indicators on the host.
Does the cable require any external power source?
No external power is required; the active optical transceiver draws its power directly from the QSFP+ host port.
What is the typical power consumption of this active optical cable?
The QSFP-H40G-AOC20M= consumes less than 1 W per end, making it highly efficient for dense port deployments.
What is the operating temperature range?
The cable is rated for 0 °C to 70 °C (32 °F to 158 °F), covering standard and harsh data center conditions.
How do I troubleshoot connectivity issues?
Verify port compatibility, inspect connectors for debris, reseat the cable, and confirm link lights and host OS diagnostics for errors.
What warranty and support options are available?
Standard manufacturer’s warranty covers defects for one year, with optional extended support and replacement services.
How does the QSFP-H40G-AOC20M= compare to a copper DAC?
Compared to direct-attach copper, the optical cable offers longer reach, lower EMI, reduced weight and better signal integrity at 40 Gbps.
Can I mix this AOC with breakout cables or modules?
No. The QSFP-to-4xSFP+ breakout function is not supported on this AOC; it must be used as a direct QSFP+-to-QSFP+ link.
Does the cable comply with industry standards?
Yes. It meets IEEE 802.3ba for 40GBASE-SR4 and SFF-8436 QSFP+ MSA specifications for interoperability.
What maintenance is required for the active optical cable?
Periodic visual inspection and end-face cleaning with approved optical cleaning tools are recommended to maintain optimal performance.
