QSFP to SFP+ Adapter for Cisco Platforms

The Cisco CVR-QSFP-SFP10G= adapter module provides 10 Gigabit Ethernet and 1 Gigabit Ethernet connectivity for QSFP-only platforms. It enables the use of SFP or SFP+ transceivers in empty QSFP ports. This silver adapter supports smooth and cost-effective migration toward 40 Gigabit Ethernet environments. It is designed for network administrators managing Cisco infrastructure.

Verify Port Availability

Confirm that your switch or router has vacant QSFP ports before ordering. Ensure the SFP or SFP+ modules you intend to use are compatible with the target platform and support the required 10 Gigabit or 1 Gigabit Ethernet speeds. Check that the adapter’s physical dimensions suit the chassis density and airflow design. Validate that the operating system version recognises the QSA module.

Integrates into Existing QSFP Infrastructure

The adapter occupies a single QSFP port to free up budget by leveraging existing lower-speed optics. It requires compatible SFP or SFP+ transceivers and appropriate cabling to complete the link. No additional power supply or cooling changes are needed beyond the host system specifications. The module allows phased upgrades without replacing higher-speed backbone equipment.

Questions about this item

Does the CVR-QSFP-SFP10G= package include SFP or SFP+ transceivers, or must they be purchased separately?

The adapter module itself is supplied; SFP or SFP+ transceivers are not included and must be bought separately to match the desired link speed.

When should I use this QSA module instead of a native QSFP+ transceiver?

Choose the CVR-QSFP-SFP10G= when you need 10 Gigabit Ethernet or 1 Gigabit Ethernet connectivity on a QSFP-only platform, or when the remote end runs at lower speeds.

What throughput can I expect when a 10G SFP+ transceiver is inserted into this adapter?

The link will operate at 10 Gigabit Ethernet, the maximum rate supported by the SFP+ module through the QSA adapter.
