Transceptor de fibra ótica SFP28 25G CBO SFP28-25G-SR BO27Q856S1D, 25 Gbit/s, SR multimodo

The CBO SFP28-25G-SR BO27Q856S1D is a compact SFP28 fiber optic transceiver designed for short-reach multimode links at 25 Gbps. It fits into standard SFP28 ports and provides low-latency optical connectivity for switches, servers and network interface cards. The module is intended for data center and enterprise environments where reliable, hot-swappable 25G links are required over multimode fiber.

Advantages

This SFP28 transceiver supports native 25 Gbps data rates for high-throughput applications and maintains compatibility with SFP28 host ports for straightforward installation. Its multimode SR design enables short-reach connectivity across MPO/LC-based multimode fiber infrastructures with predictable optical performance. The module is hot-pluggable, compact and suitable for dense rack deployments where space and power efficiency are important.

Suitable for

• 25G short-reach links between switches in top-of-rack and spine architectures
• Server to switch uplinks where low-latency 25G connectivity is required
• High-density data center patching on multimode fiber cabling

Key specifications

• Form factor: SFP28 (small form-factor pluggable 2.8)
• Data rate: 25 Gbps
• Optical type: Short Reach (SR) for multimode fiber
• Connector type: duplex LC
• Hot-pluggable: yes
• Typical application: 25G Ethernet and compatible protocols over multimode fiber

How to use

Insert the transceiver into a compatible SFP28 port on the switch, server or NIC until it latches. Connect duplex multimode LC patch cords to the transceiver and to the corresponding device or patch panel. Ensure fiber polarity and link partner configuration match the 25G SR multimode requirements. The device is hot-swappable, so it can be inserted or removed while equipment is powered, but follow host vendor guidelines for port enablement and firmware compatibility.

Recommendations

For reliable link performance, use high-quality OM3/OM4 multimode fiber and verify cable length remains within SR reach specifications. Check host device compatibility lists and, when available, update transceiver-related firmware. Avoid touching fiber endfaces and follow standard ESD precautions when handling the module.
