## Long description

The BLUEOPTICS GCZ27AT is an SFP28 transceiver module designed for 25Gbps serial optical links. This hot-pluggable module provides a compact interface for switches, servers and uplinks in data center and enterprise networks, enabling reliable high-speed data transmission. The module supports fibre connections for short- and extended-reach deployments and is intended for upgrading or expanding existing 25Gbps ports with a plug-and-play installation approach.
Advantages
The SFP28 transceiver delivers 25Gbps line-rate performance while maintaining a small form factor compatible with standard SFP28 cages. Hot-pluggable capability allows insertion and removal without powering down the host device, simplifying maintenance and replacements. The module supports different optical fibre types to accommodate short-reach and longer-reach scenarios, offering flexibility for varied network topologies. Its compact design reduces space usage in dense rack environments and helps scale uplink capacity with minimal hardware changes.
Suitable for
 Connecting 25Gbps uplinks between switches and aggregation devices
 High-speed server-to-switch links in rack and blade servers
 Data center spine-and-leaf networks requiring 25Gbps ports
 Expanding or upgrading existing 10Gbps infrastructures to 25Gbps
Key specifications
 Interface: SFP28 form factor for 25Gbps serial optical transmission
 Data rate: 25 gigabits per second
 Connector type: optical fibre connector (module accepts standard fibre connectors)
 Optical reach: suitable for short- to longer-reach fibre links depending on fibre type and optics
 Hot-pluggable: supports live insertion and removal without host shutdown
 Compatibility: designed for standard SFP28 ports on switches, routers and server NICs
How to use
Install the BLUEOPTICS GCZ27AT into an available SFP28 port on a switch, router or server NIC by aligning the module with the port and gently inserting until it clicks into place. Connect the appropriate optical fibre patch cable to the module's connector, ensuring the cable type and connector match the intended reach and equipment requirements. The module is hot-pluggable, so it can be inserted or removed while the host is powered, but follow your equipment vendor's guidelines for link activation and diagnostics. Monitor link status via the host device to confirm correct operation and signal integrity.
Usage recommendations
 Verify that the optical fibre type (single-mode or multi-mode) and connector standard you use are compatible with the intended reach and with the host equipment. Use clean, certified fibre patch cables and inspect connector endfaces before mating to avoid signal degradation. Follow the network equipment vendor’s firmware and compatibility notes and perform link tests after installation to validate throughput and error rates.
