Cisco Parts Accessory Model Overview
Frequently Asked Questions
What is the maximum transmission distance for the Cisco QSFP-40G-ER4 transceiver?
The Cisco QSFP-40G-ER4 is designed for extended-range 40 Gigabit Ethernet transmission over single-mode fiber with LC connectors. This module supports long-distance data networking applications, making it suitable for campus and metropolitan area network deployments. We offer this transceiver module as part of our comprehensive Cisco networking components catalog.
Is the Cisco QSFP-40G-ER4 compatible with my existing network infrastructure?
The QSFP-40G-ER4 is a hot-swappable QSFP module that works with Cisco switches and routers equipped with QSFP ports supporting 40GBASE-ER4 standards. Compatibility depends on your specific network equipment and its firmware version. Contact us today to verify compatibility with your infrastructure and ensure seamless integration.
What are the key differences between the QSFP-40G-ER4 and other 40G transceiver modules?
The ER4 variant is optimized for extended-range transmission over single-mode fiber, whereas SR4 modules are designed for shorter distances on multi-mode fiber, and LR4 modules offer intermediate range capabilities. The ER4's extended reach makes it ideal for longer metropolitan and campus network spans. We offer multiple 40G transceiver options to match your specific distance and infrastructure requirements.
What fiber type does the Cisco QSFP-40G-ER4 require?
The QSFP-40G-ER4 operates over single-mode fiber (SMF) with LC duplex connectors, supporting the 40GBase-ER4 standard. Single-mode fiber enables the extended transmission distances this module is engineered to deliver. Visit barcodesinc.com to verify your fiber infrastructure compatibility before ordering.
Can I use the QSFP-40G-ER4 in a high-density data center environment?
Yes, the QSFP-40G-ER4 is a compact, hot-swappable transceiver designed for high-density network deployments in data centers and telecommunications facilities. Its QSFP form factor allows multiple modules to be installed in closely-spaced ports on compatible equipment. Our team can help you plan deployments that maximize port density while maintaining optimal airflow and thermal management.
What should I know about the operational wavelength of the QSFP-40G-ER4?
The QSFP-40G-ER4 operates at 1310 nm wavelength, which is the standard for extended-range single-mode fiber transmission in 40 Gigabit Ethernet applications. This wavelength provides optimal performance over longer distances compared to shorter-wavelength modules.
