FAQ
Questions about this model.
What link distance is listed for the 25G SFP28 ZR 1310nm 80km Single-Mode Duplex LC Long-Reach?
The listed reach is 80 km. Actual distance depends on the installed fibre loss, the number of connectors and splices and the receiver sensitivity at both ends, so confirm the optical budget for your own path before ordering. Our link budget calculator works through the arithmetic in a minute.
Which wavelength does this module use?
It is listed at 1310 nm. Both ends of a duplex link must use the same wavelength plan.
What connector and fibre does it need?
The listed interface is Duplex LC on Single-Mode (SMF). Check that your patch cords, panel adapters and polarity match before installation.
Can it be coded for my switch?
Yes. Send the host manufacturer, the exact model and the software version with your inquiry. Coding is confirmed per platform before production — a connector that fits does not by itself prove the host will accept the module.
Can I evaluate a sample first?
Include the required quantity, host platform and destination in your inquiry. Sample availability, charges and lead time are confirmed in the quotation, and we recommend testing in the intended port before a bulk order.
