Módulo transceptor SFP BlueOptics SFP28-25G-ESR-BC 25000 Mbit/s 850 nm

The BlueOptics SFP28-25G-ESR-BC 25000 Mbit/s 850 nm is a compact fiber optic SFP28 transceiver module designed for 25 Gbit/s short-range data links using 850 nm wavelength. This module provides a hot-pluggable connection for switches, routers and network interface cards that accept SFP28 form factor modules. Its small dimensions and 40 g weight make it suitable for dense installation environments where stable 25 Gbit/s connectivity is required.

Advantages

The transceiver supports a maximum data transfer rate of 25 000 Mbit/s and operates at a multimode 850 nm wavelength, offering compatibility with standard 25 G Ethernet short-reach applications. As an SFP28 module it provides backward compatibility with SFP+ ports in many devices and allows straightforward hot-swap installation. The silver metal housing contributes to physical durability and thermal dissipation for stable operation under typical network conditions.

Suitable for

• 25 G Ethernet short-reach links in data centers
• High-speed uplinks between switches and aggregation points
• Server connections and NIC uplinks supporting SFP28
• Fiber patch panel interconnects within multimode cabling infrastructures

Key specifications

• Form factor: SFP28 (hot-pluggable)
• Nominal wavelength: 850 nm (multimode)
• Maximum data rate: 25 000 Mbit/s
• Typical application: short-reach multimode fiber links
• Weight: 0.04 kg
• Housing color: silver

How to use

Ensure the host device supports SFP28 modules and is powered down or prepared for hot-swap insertion according to the manufacturer's guidance. Remove protective dust caps from both the module and the fiber connector, then insert the transceiver into the SFP28 slot until it latches. Connect the appropriate multimode fiber patch cable terminated for 850 nm operation. Monitor link LEDs or the device management interface to confirm the 25 Gbit/s link is established and verify signal integrity and error counters in the network equipment.

Recommendations

Use OM3/OM4 multimode fiber for reliable 25 G short-reach performance at 850 nm, maintain clean connectors and dust caps when the module is not in use, and check compatibility charts for host equipment to ensure SFP28 support and proper firmware or driver versions.
