25 Gbps SFP28 performance for modern networks
The 25 Gbps transmission speed has become a basic requirement for modern data centers and enterprise environments. This optical module:
- Excellent solution for high-speed interconnections between servers, switches, and routers
- Ideal for serving spine-leaf topologies, virtual machine clusters, and storage area networks (SAN)
- Prepares the network for future demands, handling larger data traffic
The 25G SFP28 technology provides more efficient resource utilization than older 10G solutions, requiring fewer physical ports and cables to achieve the same bandwidth.
LC/UPC duplex connector and multimode optical cable
The module uses an LC/UPC duplex connector, which is an industry standard for high-speed optical networks. This connector type:
- Is compact, fitting well with high-port-count switches and patch panel solutions
- Provides easy, quick connection to existing LC optical cabling
- Offers a reliable, low-loss connection
The module can be used with multimode optical cable, primarily with OM3 or OM4 standard patch cables. This is an ideal choice:
- For short and medium-distance connections in server rooms
- For high-speed uplinks between rack cabinets, rows, or rooms
- In environments where cost-effective, fast optical connection is the goal
850 nm wavelength and 100-meter range
The module uses an 850 nm laser light source, specifically optimized for multimode optical transmission systems. This solution:
- Is ideal for short-range, high-density data center connections
- Provides up to 100 m range on OM3 cabling, with appropriate optical parameters
- Guarantees high reliability and stable signal transmission by minimizing signal loss
Such optical modules fit perfectly into modern network infrastructures that combine structured copper and optical cabling.
DOM function – digital optical monitoring
The module features a built-in DOM function (Digital Optical Monitoring), which allows continuous monitoring of optical parameters. From the interface of compatible network devices or management system, the following values can be monitored:
- Optical power level (TX/RX)
- Module temperature
- Power supply voltage
- Laser current
The DOM function allows for quick detection of abnormalities due to attenuation, connection errors, or cable issues, thus preventing unexpected network outages and reducing troubleshooting time.
Compatibility and application areas
The modules are designed to be widely compatible with most modern network devices, such as:
- Data center switches and aggregation switches
- Blade and rack servers with SFP28 ports
- Enterprise core and distribution level routers
- High-speed storage network devices (SAN, NAS systems)
Typical application areas:
- 25G uplink connections between servers and top-of-rack switches
- Interconnections between switches in spine-leaf architectures
- Networking of virtualization clusters and hyper-converged systems
- Building high-availability, redundant optical links
Two modules in one package – flexible expansion option
The package contains two optical modules with identical parameters, which:
- Facilitates the establishment of redundant connections or aggregated links
- Is ideal for paired switch-switch or switch-server connections
- Provides a cost-effective solution when activating multiple 25G ports simultaneously
The modules can also be used as backup units, ensuring that a replacement device is immediately available in case of failure, minimizing downtime.
Reliability and network stability
The optical modules are designed for continuous, intensive use, making them excellent for:
- Non-stop operating data center environments
- Core network connections of enterprise-critical systems
- Situations where network stability is a primary concern
Thanks to precise manufacturing processes and strict quality control, the modules operate reliably over the long term, ensuring that the entire optical network operates predictably and securely.
