Frequently Asked Questions

What is the primary application for the Dell Q28-100G-SR4-85C transceiver? +

The Dell Q28-100G-SR4-85C is designed for high-density 100GbE data center interconnects. It is optimized for short-reach applications, utilizing multi-mode fiber to provide high-speed connectivity between switches, routers, and servers within a rack or across adjacent rows in a modern enterprise data center environment.

Does the Q28-100G-SR4-85C support MPO/MTP connectivity? +

Yes, this transceiver utilizes an MPO-12 (Multi-fiber Push On) interface. This connector type allows for parallel optical data transmission, which is standard for SR4 modules to achieve 100Gbps throughput. Ensure your structured cabling infrastructure is equipped with MPO/MTP multi-mode fiber patches to guarantee a seamless physical layer installation.

What is the maximum effective reach of the Q28-100G-SR4-85C over OM4 fiber? +

When paired with OM4 multi-mode fiber, the Q28-100G-SR4-85C supports link distances up to 100 meters. This makes it an ideal choice for intra-data center cabling where low-latency, high-bandwidth links are required to connect core switching hardware without the need for more expensive, long-haul single-mode solutions.

Is the Dell Q28-100G-SR4-85C compatible with non-Dell networking hardware? +

While specifically engineered for Dell networking platforms, QSFP28 modules follow industry-standard form factors. However, for maximum stability and to avoid potential system-level alerts, it is recommended to utilize these modules within certified Dell switch environments to ensure full interoperability and compliance with the switch’s operational protocols.

How do I ensure the Q28-100G-SR4-85C operates within optimal temperature ranges? +

The '85C' designation in the part number indicates the module is rated for industrial or extended temperature ranges. To maintain performance, ensure your switch rack has adequate airflow and that the port cage is free of debris. Monitoring the module's internal temperature via the switch CLI is recommended to prevent thermal throttling.

Does the Q28-100G-SR4-85C require any specific switch-side configuration? +

Generally, these transceivers are plug-and-play. Once inserted into a compatible QSFP28 port, the switch should automatically detect the module type and link speed. In some high-density environments, you may need to explicitly configure the port speed to 100GbE or manage breakout configurations if the switch port supports splitting into 4x25GbE channels.

Can the Q28-100G-SR4-85C be used for breakout cable applications? +

Yes, the SR4 architecture is designed to support 4x25GbE breakout configurations. By using an MPO to 4xLC breakout cable, you can effectively split a single 100G QSFP28 port into four individual 25GbE connections, providing significant flexibility for connecting lower-speed leaf switches or high-performance server NICs to your core distribution layer.

What power consumption should I anticipate for this 100G module? +

The Q28-100G-SR4-85C is engineered for power efficiency, typically consuming less than 3.5 Watts. This low power profile is critical for maintaining overall rack power budgets, especially in high-density deployments where hundreds of these transceivers may be populated in a single chassis-based switch configuration.
