LEX3881-2F
10GBASE-R to 10GBASE-R media converter
The LEX3881-2F is the world’s smallest*1 Ethernet OAM compatible media converter.
-
The LEX3881-2F is an Ethernet OAM-compatible media converter equipped with Link
OAM/CFM OAM functions. It is the world's smallest*1 Ethernet OAM-compatible media converter.
The LEX3881-2F has operation, management, and maintenance functions for Ethernet networks,
such as status monitoring of lines connecting neighboring devices, monitoring of connection
failures between multiple devices, throughput measurement, frame loss measurement, and frame
delay measurement. It is highly cost effective and provides stable transmission quality via
quick and easy identification and isolation of failure factors.In addition, it is equipped
with a Dying Gasp function that remotely indicates an instantaneous power-off such as a power
outage, enabling a prompt response to the power failure.
*1 Among stand-alone Ethernet OAM compatible Giga media converters,
according to FXC’s findings as of April 18, 2018.
