Origin Storage Optical Transceiver 25GbE SFP28 LC-LC 850nm SR up to 100m

The QNAP TRX-25GSFP28-SR network transceiver module is a short-range fiber optic SFP28 solution engineered for 25 Gbps links. Designed for use in data centers and enterprise network environments, this module supports up to 25,000 Mbit/s data transfer over multimode fiber at an 850 nm wavelength. Its compact SFP28 form factor and stainless steel housing provide compatibility with SFP28 ports and physical durability for rack-mounted switches, servers, and transceivers.

Advantages

The module delivers high-bandwidth performance for short-reach connections while maintaining a small footprint suitable for high-density installations. Operating at 850 nm, it is optimized for multimode fiber use and provides consistent throughput up to 100 m. The stainless steel construction enhances physical robustness and helps protect optical components during installation and operation.

Suitable for

• 25 Gbps server-to-switch links in data center racks
• Short-range uplinks between aggregation switches
• High-density campus network connections over multimode fiber
• Applications requiring SFP28 compatibility and compact transceiver modules

Key specifications

• Maximum data transfer rate: 25000 Mbit/s
• Optical wavelength: 850 nm
• Maximum transfer distance over multimode fiber: 100 m
• Form factor: SFP28
• Housing material: stainless steel

How to use

Install the transceiver into a compatible SFP28 slot on a switch, server, or network adapter and secure it according to the host device manufacturer’s instructions. Connect multimode fiber optic patch cables with the appropriate LC connectors, ensuring proper polarity and clean end faces. After physical installation, verify link status and configure interface settings on the network device as needed to enable 25 Gbps operation.

Recommendations

Use verified multimode fiber and LC patch cords rated for 25 Gbps links, keep fiber end faces clean, and follow ESD precautions during handling. Select appropriate cable type and length—up to 100 m—to maintain optimal signal integrity for short-range deployments.
