Frequently Asked Questions
Is this StarTech.com QSFP40GSR4ES compatible with existing Dell EMC networking hardware? +
Yes, this transceiver is specifically programmed and tested to ensure full compatibility with Dell EMC switches and routers that require the QSFP-40G-SR4 standard. It functions as a direct equivalent to the OEM part, ensuring that your network hardware recognizes and initializes the module without triggering compatibility errors or performance bottlenecks.
What is the maximum reach for this 40GBASE-SR4 fiber optic module? +
This module is designed for short-reach data center applications, supporting a maximum distance of up to 150 meters over OM4 multimode fiber. When using OM3 cabling, the distance is typically reduced to 100 meters. It uses an 850nm wavelength, making it an ideal choice for high-speed connectivity within server racks or between adjacent rows in your facility.
Does the QSFP40GSR4ES support Digital Diagnostic Monitoring (DDM)? +
Absolutely. This transceiver features built-in Digital Diagnostic Monitoring (DDM) capabilities, which allow network administrators to monitor real-time operating parameters such as optical output power, input power, temperature, and transceiver supply voltage. These insights are critical for proactively troubleshooting fiber links and ensuring long-term network reliability.
What type of fiber optic connector is required for this QSFP+ transceiver? +
This module utilizes an MPO (Multi-fiber Push-On) connector interface, which is the standard for 40GBASE-SR4 parallel optics. You must ensure your cabling infrastructure uses MPO/MTP patch cables with the correct polarity to support the four transmit and four receive channels required for full 40Gbps throughput.
Can I use this 40G transceiver in a network environment with mixed-vendor equipment? +
While this module is optimized for Dell EMC environments, it is built to industry-standard MSA (Multi-Source Agreement) specifications. This broad compliance allows for greater flexibility in heterogeneous network environments. However, for critical production deployments, we recommend verifying that your specific host device port configurations are set to accept third-party transceivers.
What are the primary power consumption characteristics of this QSFP+ module? +
This module is engineered for power efficiency, maintaining low power consumption levels consistent with standard QSFP+ specifications. By utilizing high-quality optics and efficient internal components, it helps keep the overall thermal load on your Dell EMC switches lower, contributing to a more stable and energy-efficient data center environment compared to older or non-optimized hardware.
How does the performance of this StarTech.com module compare to the original Dell OEM part? +
StarTech.com transceivers are built to match or exceed the performance specifications of the OEM versions. You can expect identical 40Gbps data throughput and low-latency performance. Because each module is rigorously tested for reliability and signal integrity in real-world scenarios, it provides a dependable alternative for high-density networking tasks without compromising your connection speed.
Are there specific deployment scenarios where this 40GBASE-SR4 module is best utilized? +
This module is perfectly suited for high-density interconnects, such as connecting top-of-rack switches to core distribution switches within the same data center room. Because it leverages multimode fiber, it provides a cost-effective solution for short-range, high-bandwidth applications where the performance demands of 40GbE are required without the cost associated with single-mode laser optics.
Do you offer bulk pricing or special quotes for large-scale infrastructure projects? +
We specialize in supporting enterprise-level upgrades and large-scale deployments. If you are planning a significant network expansion and require a large volume of QSFP+ modules, please reach out to our sales team directly. We are happy to provide customized bulk quotes to help you manage your procurement budget more effectively while ensuring your project stays on schedule.
Why should I choose BuyRouterSwitch.com for my enterprise networking hardware needs? +
