how to install QNAP Optical Transceiver 25GBE SFP28 LC-LC 850NM SR UP TO 100M
- Power down or gracefully shut down the host equipment if required by your deployment policy, then access the chassis or server's SFP28 slot area where the transceiver will be inserted.
- Holding the transceiver by its housing, align the module with the SFP28 slot and gently insert straight into the connector until it seats securely. Do not apply excessive force; a firm click usually indicates proper seating.
- Attach the fiber optic cable to the LC duplex connectors with the correct polarity, ensuring the transmit (Tx) and receive (Rx) lanes align with the corresponding ports on the other end of the link.
- Power on the equipment and verify link status. Most devices will indicate a solid link LED when the transceiver is functioning correctly and negotiation is complete.
- Run a basic connectivity test using standard network tools to confirm bandwidth, latency, and error rates. If available, enable any built‑in diagnostics or DOM/DDM monitoring to verify performance metrics such as optical power levels and temperature.
- Document the installation, including the device model, slot, cable type (OM3/OM4), link distance, and any observed performance metrics, to support future maintenance and upgrades.
Frequently asked questions
- What is 25GBASE‑SR? 25GBASE‑SR is a short‑reach 25 Gigabit Ethernet specification that uses multimode fiber and VCSEL optics for high‑speed data transmission over relatively short distances, typically up to 100 meters depending on fiber type and quality. It is widely used for high‑density server connections, high‑bandwidth storage networks, and inter‑rack uplinks in data centers.
- What does SR mean in this transceiver? SR stands for Short Reach. It indicates the module is optimized for short‑distance links on multimode fiber, providing excellent performance for intra‑rack and intra‑data center connectivity with low insertion loss and robust link budgets.
- Can this transceiver work with non‑QNAP equipment? Yes. The QNAP 25GBase‑SR SFP28 module adheres to standard SFP28 form factors and is designed to be interoperable with other vendors’ 25GBase‑SR capable switches, NICs, and storage devices, as long as the devices support SFP28 optics and OM3/OM4 multimode fiber.
- What fiber type and cable are recommended? Multimode fiber (OM3 or OM4) is recommended for SR 25G links up to 100 meters. Ensure proper termination, cleaning, and handling of fiber to maintain the optical performance and minimize loss.
- Is there any special maintenance required? The transceiver is designed for reliable, plug‑and‑play operation. Routine maintenance focuses on keeping fiber ends clean, monitoring link health, and performing firmware or driver updates on connected devices as needed. If you notice degraded link quality, re‑seat the module and re‑test the connection.
- What applications best fit this transceiver? This module is well suited for data center uplinks, storage area network backbones, virtualization environments, hyper‑converged infrastructure, and edge deployments where high throughput, low latency, and compact form factors are critical.
