Transceptor SFP28 CBO SFP28-25G-ESR-PS-BO 25Gb/s módulo de fibra ótica ESR

CBO SFP28-25G-ESR-PS-BO is a 25Gb/s SFP28 ESR fiber optic transceiver module designed for short-range multimode links in data center and enterprise networks. The module implements the SFP28 form factor and supports 25 Gigabit Ethernet transmission over multimode fiber, allowing low-latency, high-bandwidth connectivity between switches, servers and storage systems. Its compact design is compatible with standard SFP28 ports and simplifies migration from lower-rate interfaces while preserving port density.

Advantages

The SFP28 ESR module delivers 25Gb/s line-rate performance with low power consumption and a small SFP28 footprint for dense installations. Its ESR (Extended Short Range) optics provide reliable multimode operation for short links typically found inside racks and across adjacent racks. The module supports hot-pluggable insertion, enabling fast replacements or upgrades without powering down equipment. Built-in diagnostics and standard electrical/optical interfaces ensure interoperability with compliant network equipment.

Suitable for

• 25 Gigabit Ethernet uplinks between top-of-rack and aggregation switches
• Server and storage connections requiring low-latency, high-bandwidth links
• Short-range multimode fiber links inside data centers and server rooms
• Network upgrades where maintaining SFP28 port density is important

Key specifications

• Nominal data rate: 25 Gb/s
• Form factor: SFP28 (hot-pluggable)
• Optical reach: extended short range over multimode fiber
• Fiber type: multimode fiber (MMF)
• Connector interface: duplex LC
• Typical power consumption: low-profile SFP28 class
• Supported standard: 25 Gigabit Ethernet

How to use

Insert the SFP28 transceiver into a compatible SFP28 port on a switch, server NIC or storage adapter until it latches. Connect duplex LC multimode fiber patch cords, observing correct transmit/receive orientation. After insertion, verify link status through device LEDs or management interface; the link should negotiate at 25 Gb/s with compatible equipment. For safe removal, disable the port or follow the host device’s hot-swap procedure, then depress the SFP28 bail or release mechanism and pull the module straight out.

Recommendations

Use high-quality OM3/OM4 multimode fiber and clean LC connectors to ensure optimal optical performance. Avoid tight bends near the transceiver and secure patch cords to reduce strain. Test and document link parameters after installation and keep spare modules for quick replacements in critical paths.
