MTBF (Mean Time Between Failures): Conventional models have a maximum of 1339439 hours, while some models have a minimum of 989940 hours, in compliance with Telcordia (Bellcore) and GB standards.

Key to Model Classification and Selection
There are a total of 22 sub models in the entire series, with core selection dimensions including port configuration, operating temperature, and industrial protocol. Some mainstream models are shown in the table below:
The model type represents the core differences of the model
Full RJ45 port EDS-408A (standard temperature) with 8 RJ45 ports, no fiber optic ports, suitable for short distance wired interconnection
EDS-408A-T (wide temperature range) as above, suitable for low/high temperature industrial environments
Equipped with multi-mode fiber EDS-408A-MM-SC, 6 RJ45+2 multi-mode SC fibers, with a transmission distance of 4km, suitable for medium to short distance fiber networking
Equipped with single-mode fiber EDS-408A-SS-SC, 6 RJ45+2 single-mode SC fibers, with a transmission distance of 40km, suitable for long-distance (such as cross regional interconnection in the factory area) interconnection
Industrial protocol customization EDS-408A-EIP 8 RJ45, default enabled EtherNet/IP protocol
EDS-408A-PN 8 RJ45, default enabled PROFINET protocol
Hybrid fiber type EDS-408A-1M2S-SC 5 RJ45+1 multimode SC+2 single-mode SC, meeting the needs of medium to short/long-distance fiber
Selection tip: The model with "- T" at the end is for wide temperature version, and with "-48" is for bipolar voltage version. It needs to be selected according to the actual environmental temperature, power supply type, and transmission distance requirements.
