When choosing a 100G ZR4 optical module, ensure it comes from a trusted manufacturer with certifications such as CE, FCC, and RoHS. Reputable suppliers also provide detailed datasheets, customer support, and warranty services.
Transmission Distance: Confirm support for 80km.
Connector Type: Ensure LC duplex compatibility.
Wavelength: 1310nm is the standard for ZR4.
Compliance: Must meet 100GBASE-ZR4 and QSFP28 interface standards.
Look for modules that can operate between 0°C and 70°C, ensuring stable performance even in varied data center conditions. DOM monitoring is also essential for real-time diagnostics.
While ZR4 modules may cost more upfront than LR4 or ER4, they reduce the need for intermediate equipment, lowering total ownership costs. The investment pays off in long-term stability and reduced maintenance.
A three-year warranty and responsive technical support are important. Reliable vendors also provide quick delivery and flexible minimum order quantities, making them practical for both testing and deployment.
