  • Device TypeTransceiver
  • 31 Gbps throughput for high-bandwidth links
  • 300 m reach over multi-mode fibre at 850 nm

ADTRAN 10.31 Gbps SFP Transceiver

This ADTRAN LTF8502-BE module provides 10.31 Gbps connectivity over multi-mode fibre. It suits network links where short-reach optical connections are required. The transceiver fits standard SFP slots in compatible switches or routers.

Thermals, Noise and Power

As a passive optical transceiver it has no moving parts and generates no audible noise. Heat output is minimal and handled by the host equipment airflow. Power consumption stays within the standard SFP envelope for this data rate.

DDM Monitoring Capability

Digital Diagnostic Monitoring is supported, letting the host system read real-time temperature, voltage and optical power levels. This visibility helps administrators verify link health and plan maintenance without extra tools. The 4.6 dB optical budget covers 300 metre runs at 850 nm.

Questions about this item

How do I install the ADTRAN LTF8502-BE into an SFP+ port and what step is often missed?

Insert the module until it clicks, then remove the dust caps and connect the multi-mode fibre with LC connectors; the step often missed is cleaning both connector end-faces before mating.

What maintenance or replacement will the ADTRAN LTF8502-BE need over time?

The transceiver itself has no user-serviceable parts; plan to re-clean the LC ferrules and inspect the multi-mode fibre patch cords whenever link budget drops toward the 4.6 dB minimum.

What limit appears first on the ADTRAN LTF8502-BE during sustained 10.31 Gbps operation?

The 300 metre reach on 850 nm multi-mode fibre is the first hard limit; modal dispersion caps distance before the 4.6 dB optical budget is exhausted.
