Cisco Parts Accessory Model Overview
Frequently Asked Questions
What is the Cisco QSFP-40G-SR4-RF transceiver used for?
The Cisco QSFP-40G-SR4-RF is a 40GBASE-SR4 QSFP transceiver module designed for short-range optical network connections over multi-mode fiber. This hot-swappable module is ideal for high-speed data center and campus network deployments where 40 Gigabit Ethernet connectivity is required over shorter distances. We offer this transceiver module as part of our comprehensive Cisco networking components catalog.
What type of optical fiber does the QSFP-40G-SR4-RF support?
The QSFP-40G-SR4-RF transceiver module is designed for multi-mode optical fiber connections, making it suitable for shorter-distance network runs typical in data centers and enterprise environments. The module features QSFP form factor connectivity and supports 40 Gigabit Ethernet speeds over multi-mode fiber infrastructure. Contact us today to verify compatibility with your existing fiber optic network setup.
Is the Cisco QSFP-40G-SR4-RF hot-swappable?
Yes, the Cisco QSFP-40G-SR4-RF is a hot-swappable transceiver module, allowing you to install, replace, or remove it without powering down your network equipment. This feature minimizes downtime during maintenance, upgrades, or troubleshooting in production network environments. We stock this hot-swappable module to support your network infrastructure needs.
How does the QSFP-40G-SR4-RF compare to longer-range transceiver options?
The QSFP-40G-SR4-RF is optimized for short-range connections over multi-mode fiber, while longer-range options like the Cisco QSFP-40G-LR4-S-RF use single-mode fiber and LC connectors for extended distances up to 10km. If your network requires extended transmission distances, single-mode transceiver modules are available from us, but the SR4 variant is ideal for high-speed, short-distance data center interconnects.

What connector type does the QSFP-40G-SR4-RF use?
The Cisco QSFP-40G-SR4-RF features QSFP (Quad Small Form-factor Pluggable) connectors designed for multi-mode fiber connections in 40 Gigabit Ethernet applications. This compact form factor allows for higher port density in network switches and routers compared to larger transceiver modules. Available from us with full compatibility verification for your network equipment.
Can I use the QSFP-40G-SR4-RF in different network equipment?
The Cisco QSFP-40G-SR4-RF is designed to work with Cisco networking equipment and other devices that support standard QSFP modules and 40GBASE-SR4 specifications. Compatibility depends on your specific switch, router, or network interface card supporting this transceiver standard.
