## Long description

The BLUEOPTICS BO27Q856S1D compatible SFP28 transceiver module (marketed as PY-SFPS56-BO) is a compact, hot-pluggable optical interface designed for 25 Gigabit Ethernet (25GbE) links. It fits standard SFP28 ports on switches, routers and media converters to provide an upgrade path for higher-speed server uplinks, aggregation links and leaf–spine fabrics in data center and enterprise networks. The module supports short-reach single-mode/multimode topologies as defined for SFP28 optical modules and is intended for environments that require reliable 25GbE connectivity without changing existing port hardware.
Advantages
The module provides a small, standardized form factor that enables straightforward upgrades to 25GbE on compatible network devices without replacing entire line cards. Its hot-pluggable design allows installation and replacement without powering down equipment, minimizing downtime during maintenance. The SFP28 interface ensures backward compatibility with SFP+/SFP28 cages and supports interoperable optical links with a range of switches and media converters that accept SFP28 modules. Its compact size and standardized electrical/optical specifications simplify spare-part management and density planning in rack and data center deployments.
Suitable for
Upgrading switch uplinks to 25GbE in data centers and server rooms
Establishing high-speed links between aggregation and leaf switches
Replacing or stocking spare transceivers for enterprise and telecom equipment with SFP28 ports
Connecting media converters and network adapters that support 25GbE SFP28 modules
Key specifications
Form factor: SFP28 pluggable module compatible with 25GbE ports
Interface: Hot-pluggable electrical and optical SFP28 connector
Data rate: 25 Gigabit Ethernet (25GbE)
Application: Short-reach optical links for data center and enterprise networks
Compatibility: Designed to operate with standard SFP28-compatible network equipment
How to use
Ensure the target device supports SFP28 modules and 25GbE operation, then power the device according to the manufacturer's instructions. Carefully insert the transceiver into an empty SFP28 cage until it clicks into place and establish a fiber patch or direct attach connection following correct polarity and fiber type guidance. After insertion, verify the link status on the host device and configure interface settings such as speed, duplex and auto-negotiation if required by the network equipment. To remove the module, follow the host device's hot-swap procedure and handle the optical interfaces with appropriate dust caps and protective measures.
Usage recommendations
Use suitable fiber cable type and approved SFP28-compliant patching components to ensure signal integrity. Observe manufacturer guidelines for operating temperature and ESD handling. For critical links, verify compatibility with the switch vendor and test the transceiver in a controlled environment before widespread deployment.
