1. Confirm the multimode link conditions first.
The Axonode 25GBASE-SR SFP28 100m transceiver supports up to 25.78Gbps over duplex multimode fiber. Confirm the fiber grade, duplex LC patching, host port mode and total link length before deployment.
25G SFP28 Port
Confirm that the host device supports a 25G SFP28 port and the required compatibility coding.
Duplex LC / MMF
Use duplex LC cabling with compatible 50/125um multimode fiber.
Reach Up to 100m
Supports up to 100m on OM4, 70m on OM3 and 20m on OM2.

3. Short-reach 25G deployment
This transceiver is intended for short 25G links such as server-to-switch, access-to-aggregation and data-center interconnects where duplex multimode fiber is available. Confirm the installed fiber grade because the supported reach changes between OM2, OM3 and OM4.
4. Compatibility prepared for your network
Compatibility coding must be confirmed for the actual switch, server adapter or router. Share the equipment brand, exact model, software or firmware environment, port mode and DDM requirements before ordering.
5. Quality and compliance
The module is designed around the SFP28 electrical interface, SFP+ MSA mechanical requirements and SFF-8472 digital diagnostics. Compliance statements do not replace host-platform compatibility verification.
6. Comprehensive testing
Testing can include wavelength, transmit power, receiver response, DDM readings, host recognition and link establishment according to the product and project requirements.
Frequently Asked Questions
i. What fiber supports the full 100m reach?
Use 50/125um OM4 multimode fiber for links up to 100m. The verified limits are 70m on OM3 and 20m on OM2.
ii. Does this module use simplex or duplex LC?
It uses a duplex LC interface with separate transmit and receive fibers.
iii. Can it be used on single-mode fiber?
No. This 850nm SR module is specified for multimode fiber. Choose a suitable 1310nm single-mode SFP28 for an SMF link.
iv. What should be confirmed before installation?
Confirm the host model, 25G port mode, compatibility coding, fiber grade, duplex LC polarity and link length.
v. Does it support DDM or DOM?
Yes. The verified record supports digital monitoring of temperature, supply voltage, bias current and optical power.
vi. Is compatibility guaranteed by the SFP28 form factor?
No. Mechanical fit does not prove host acceptance. Coding, port mode, software and firmware requirements must be checked for the target device.
vii. What should be checked if the link does not come up?
Check port speed, coding, LC polarity, connector cleanliness, fiber grade, link length and DDM readings at both ends.
viii. Can this module operate outside 0 to +70 degrees C?
The verified commercial option is 0 to +70 degrees C. Confirm another temperature class before using it outside that range.
