WTD RTXM192-400 2.5G optical module

The Supersuperuncle WTD RTXM192-400 is a single-mode Gigabit optical module with an ESFP interface. It operates at a 2.5 G data rate and supports a 2 km transmission distance over single-mode fibre. The module is supplied new for compatible WTD equipment.

Suits 2 km single-mode links; not for other reaches

This module fits networks that need a 2.5 G single-mode connection up to 2 km. Buyers who require a different reach, a multi-mode variant, or a copper interface should look at other modules. Compatibility with the specific host device must be confirmed before purchase.

Questions about this item

Will the 2.5G ESFP module link with my existing Gigabit switch ports?

The module runs at 2.5 Gbps and uses an ESFP single-mode interface; it will negotiate down to 1 Gbps on compatible Gigabit ports, but full 2.5G speed requires matching 2.5G-capable hardware on both ends.

How can I confirm the RTXM192-400 is operating correctly after installation?

Check the switch or router interface statistics for a stable 2.5 Gbps link, verify the optical power levels reported by the module fall within the expected single-mode range, and ensure no CRC or error counters are incrementing during traffic.
