How to install HPE 25G SFP28 LC SR 100m MMF Transceiver

• Power down or follow hot-swap procedures as required by your device, then locate an available SFP28 slot on the switch, server NIC, or storage switch.
• Remove the protective dust cap from the transceiver and inspect the LC duplex fiber connectors to ensure they are clean and free of debris.
• Insert the HPE 25G SFP28 LC SR transceiver firmly into the SFP28 slot until the module clicks into place and the latch engages securely.
• Connect the LC MMF fiber pair to the transceiver, ensuring proper polarity and cleaning connectors before insertion to minimize insertion loss.
• Power on the device (if required) and configure the port to operate at 25G. Verify link status using the device’s management interface or LEDs, then run basic throughput tests to confirm stability and performance.

Frequently asked questions

• Q: What is the maximum cable distance for this transceiver?
  A: The transceiver supports up to 100 meters on standard OM3/OM4 multi-mode fiber.
• Q: Is this module compatible with non-HPE devices?
  A: Yes. It is designed for 25GBASE-SR and should operate with other vendors’ equipment that supports the same technology, though best results are often achieved in environments with compatible firmware and driver support.
• Q: What fiber type should I use?
  A: Multi-mode fiber, preferably OM3 or OM4, to ensure the full 100 m SR reach is achieved with low attenuation.
• Q: Do I need to special‑configure the transceiver?
  A: In most cases, it will auto-negotiate to 25GBASE-SR on compatible devices. Some switches may require explicit configuration to enable 25G interfaces or adjust speed settings.
• Q: Is there any maintenance required for this transceiver?
  A: Routine fiber cleaning, connector inspection, and firmware updates for the networking devices are recommended to maintain optimal performance and link reliability.
• Q: What warranty or support comes with this module?
  A: The module is backed by HPE’s standard warranty and support terms, providing access to replacement or technical assistance as defined in your purchase agreement.
