BlueOptics SFP28-25G-ESR-NG-BO transceptor de fibra óptica SFP28 25 Gbit/s LC multimodo ESR

BlueOptics SFP28-25G-ESR-NG-BO is a fiber optic SFP28 transceiver module designed for 25 Gbit/s multimode links with an LC connector. It implements Extended Short Reach (ESR) performance, enabling high-speed, short-distance optical connections commonly used for switch uplinks, server connections and network interface cards in data centers and enterprise environments. The module is compact and follows the SFP28 form factor, allowing easy hot-plug installation into compatible ports.

Advantages

The transceiver supports a maximum data transfer rate of 25 Gbit/s over multimode fiber and uses a standardized SFP28 interface for broad compatibility with modern networking equipment. Its LC connector and ESR performance are optimized for short-range optical links up to 300 meters (depending on fiber type and link conditions). The small SFP28 package and low weight make it suitable for dense rack deployments and equipment with limited port spacing.

Suitable for

• Server uplinks and top-of-rack switch connections in data centers
• High-speed connections between switches and aggregation devices
• Network interface cards (NICs) that accept SFP28 modules
• Enterprise campus backbone links over multimode fiber

When it may not be suitable

This module is intended for short-reach multimode fiber links and may not be suitable for long-distance single-mode fiber networks or metropolitan links that require extended reach. It is not compatible with connectors other than LC and will not function in ports that do not support the SFP28 form factor or 25 Gbit/s speed.

Key specifications

• Form factor: SFP28
• Maximum data transfer rate: 25 Gbit/s
• Fiber type: Multimode
• Connector type: LC duplex
• Performance class: Extended Short Reach (ESR)
• Typical reach: up to 300 m (depends on fiber type and link conditions)
• Weight: 0.04 kg

How to use

Install the BlueOptics SFP28-25G-ESR-NG-BO by inserting the module into a compatible SFP28 port until it clicks into place, observing proper orientation. Connect LC duplex multimode fiber patch cables to the module, ensuring correct transmit/receive alignment. Verify link negotiation on the connected devices and configure the switch or host interface for 25 Gbit/s operation if manual settings are required. Handle the module carefully, keep dust caps in place when not connected, and power down or follow hot-swap procedures recommended by the equipment vendor if necessary.

What to consider before purchase

• Ensure the host device supports SFP28 modules and 25 Gbit/s operation
• Confirm the network uses multimode fiber and LC connectors
• Check required reach — ESR class is optimized for short-range links (typically up to 300 m)
• Verify vendor compatibility or any firmware/port locking policies on switches

Recommendations

Use high-quality multimode fiber (OM3/OM4) and LC duplex patch cables for optimal performance, and test links after installation to confirm signal integrity and expected throughput. Store the transceiver with dust caps when not in use and follow electrostatic discharge precautions during handling.
