25 Gbps SFP28 optical module kit for reliable data center and enterprise networks
This 2-piece SFP28 module pack is an ideal choice for modern network systems where high bandwidth, low latency, and stable operation are crucial. With a 25 Gbps data transfer speed, it is perfectly suited for data center connections, server-switch links, and the establishment of high-performance access and aggregation layers.
Main features and specifications
- 25 Gbps data transfer speed on SFP28 interface
- LC/UPC duplex connector for standard optical cabling
- 1310 nm wavelength laser diode for single-mode fiber
- Up to 10 km transmission distance on quality SM cable
- DOM (Digital Optical Monitoring) support for real-time monitoring
- Single-mode design for long-range connections
- Low power consumption and stable, reliable operation
- Hot-swap capable SFP28 transceiver module design
The modules fully support the 25 gigabit Ethernet standard, making them ideal for network switches, routers, servers, and other active devices with SFP28 slots. The package includes two identical transceivers, allowing you to immediately establish a complete optical connection or use them as backup modules.
LC/UPC duplex connector and single-mode optical cabling
The modules feature an LC/UPC duplex connector, which is the most common interface in high-speed optical networks. The connector structure:
- LC – small-sized, easy-to-handle optical connector
- UPC – ultra-physical contact, low return loss
- Duplex – two fibers, separate transmitter and receiver direction for reliable communication
Using a single-mode, 1310 nm wavelength optimized optical cable, the module can provide a stable connection up to 10 km. This makes it ideal for:
- Backbone networks between office buildings
- Data center connections
- Enterprise campus networks
- FTTx and long-distance optical link construction
DOM function – digital optical monitoring
The built-in DOM (Digital Optical Monitoring) support allows for continuous monitoring of the module's optical parameters through the network device's interface. The user can track the following values:
- Transmitter optical power
- Receiver optical power
- Module temperature
- Power supply voltage
- Laser bias current
With digital monitoring, troubleshooting, checking the condition of optical cables, and ensuring long-term stability of the network become easier. Timely detection of performance degradation or temperature rise can be managed before serious service outages occur.
Applications
The 25 gigabit SFP28 optical modules can be widely used in any environment where high-speed, reliable optical connections are required. Typical use cases:
- Connecting 25G Ethernet uplink ports between switches
- Optical connections between servers and top-of-rack switches
- Building data center spine-leaf architectures
- Establishing aggregation and backbone network segments
- Long-distance optical links in enterprise and service provider networks
The modules fit excellently into environments where 10 Gbps is already insufficient, but 40G or 100G is not yet an economical solution. The 25G technology offers an optimal price/performance ratio and integrates well into existing infrastructures.
Compatibility and installation
The SFP28 transceivers are widely compatible with devices from various manufacturers, provided they support 25G SFP28 ports. Installing the modules is straightforward:
- Turn off or set the affected network port to managed mode.
- Slide the transceiver into the SFP28 slot until the locking mechanism clicks.
- Connect the LC duplex optical cable to the transmitter and receiver ports.
- Activate the port in the network device menu and check the link status.
- If necessary, use the DOM function to check parameters.
Thanks to hot-swap support, replacing the modules can be done in most devices while operational, without shutting down the network. This minimizes maintenance time and downtime due to outages.
Why is the 2-piece packaging advantageous?
The package contains two identical SFP28 optical modules, which is practical for several reasons:
- A complete optical connection can be established immediately between two endpoints.
- One module can be actively used while keeping the other as a backup.
- More economical than purchasing modules separately.
- Using transceivers with uniform parameters in the network.
Summary: high-speed optical connection up to 10 km
This SFP28 module pack is an ideal choice for any user looking to establish a stable and long-term optical connection at 25 Gbps speed. The LC/UPC duplex connector, 1310 nm single-mode technology, 10 km range, and DOM support together provide a modern, reliable, and efficient solution in data center and enterprise network environments.
