FAQ

Questions about this model.

What link distance is listed for the 25GBASE-BR20 SFP28 BiDi Single-Fiber 1270/1330nm 20km WDM?

The listed reach is 20 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 1270 nm / 1330 nm. Single-fibre BiDi modules must be ordered as matched A/B pairs so the transmit wavelength at one end matches the receive wavelength at the other. Ordering two of the same end will not link.

What connector and fibre does it need?

The listed interface is Simplex LC on Single-Mode (SMF). Check that your patch cords, panel adapters and polarity match before installation.

Is an industrial temperature version available?

The listed operating temperature is 0 ~ 70 °C. Commercial (0~70°C) and industrial (-40~85°C) grades can be quoted; state the installed environment in your inquiry so the right grade is offered.

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.
