Product information

Description

The BlueOptics SFP28-25G-ESR-CS-BO is a fiber optic network transceiver module designed for 25 Gbit/s Ethernet applications. It uses an SFP28 interface and supports a maximum data transfer rate of 25000 Mbit/s while weighing approximately 0.04 kg. The module provides optical transmit and receive functions over multimode fiber and is suitable for short-range, high-bandwidth links where reliable, low-latency connectivity is required.

Advantages

This SFP28 transceiver offers compact SFP28 form-factor compatibility with standard LC duplex connections and is intended for 25 Gigabit Ethernet environments. It supports high-speed data transfer at 25 Gbit/s and is compatible with common network hardware such as switches and routers that accept SFP28 modules. The module’s small size and modest weight make it easy to deploy in dense rack environments. Digital diagnostic monitoring (DDM/DOM) capability enables real-time information about supply voltage, laser bias current, optical transmit and receive power, and temperature to simplify maintenance and fault analysis.

Suitable for

  • Short-range 25GbE links over multimode fiber
  • High-density switch uplinks and server connections
  • Data center top-of-rack and aggregation layer interconnects
  • Network upgrades requiring compact SFP28 transceivers

Key specifications

  • Interface type: SFP28 (SFP+ compatible form factor for 25GbE)
  • Maximum data transfer rate: 25000 Mbit/s (25 Gbit/s)
  • Optical connection: LC duplex multimode fiber (short-range optics)
  • Typical operational wavelength: 850 nm (first optical window, multimode)
  • Monitoring: Digital Diagnostic Monitoring (DDM/DOM) support
  • Weight: approximately 0.04 kg

How to use

Install the BlueOptics SFP28-25G-ESR-CS-BO by inserting the module into a compatible SFP28 port on your switch, router, or network interface card following the host device manufacturer’s hot-swap and ESD procedures. Connect an appropriate LC duplex multimode patch cable between transceivers or to a patch panel. Verify link negotiation and 25 Gbit/s operation through the host device management interface. Use the DDM/DOM registers to read real-time diagnostic parameters for verification and troubleshooting as needed.

Usage recommendations

Use high-quality OM3/OM4 multimode fiber and LC duplex patch cables for reliable short-range 25GbE links. Ensure firmware and hardware compatibility with the host device and check the device’s SFP28 support policy prior to deployment. Monitor temperature and optical power values via DDM to detect potential issues early and to maintain consistent performance.
