## Long description

The BlueOptics R0R42A-BO SFP28 100m fiber optic transceiver module is a compact, aluminum-bodied SFP28 transceiver designed for high-speed multimode fiber links. Supporting 25GBASE-SR class operation over distances up to 100 meters, this module provides bi-directional optical transmission with LC duplex connectivity. It is suitable for data center and enterprise network equipment that accept SFP28 form-factor modules and require reliable short-range 25 Gbps connectivity in a lightweight 20 g package.
Advantages
This SFP28 transceiver offers a compact SFP28 interface with multimode fiber support and LC duplex connector standard compliance. Its durable aluminium housing and low weight contribute to easy handling and installation in dense equipment racks. The module is designed for interoperability with major hardware platforms that accept compatible SFP28 modules and is intended to deliver consistent short-reach 25 Gbps performance for Ethernet and other high-speed optical protocols.
Suitable for
 25 Gbps short-reach links between switches and servers in data centers
 High-speed uplinks and aggregation within enterprise networks
 Optical connections in storage and network infrastructure using multimode fiber
Key specifications
 Form factor: SFP28
 Maximum reach: up to 100 meters over multimode fiber
 Connector type: LC duplex
 Operating data rate: up to 25 Gbps (25GBASE-SR class)
 Housing material and color: aluminium
 Weight: approximately 0.02 kg
How to use
Install the transceiver into an SFP28-compatible port on switches, routers or server network adapters according to the equipment manufacturer's hot-plug guidelines. Connect LC duplex multimode fiber patch cords, ensuring correct polarity for transmit and receive fibers. Verify link status and negotiated speed on the host device. If required by your hardware, enable or verify compatibility settings so the host recognizes third-party SFP28 modules.
Usage recommendations
Use high-quality multimode fiber patch cords and maintain proper connector cleanliness to achieve the specified 100 m reach and optimal signal integrity. Confirm that the target hardware supports 25G SFP28 transceivers and, if available, enable digital diagnostics monitoring (DDM/DOM) on the host to monitor parameters such as optical power and temperature for ongoing maintenance.
