LEX1821-2F
LEX1821-2F is a media converter for connecting the SFPs of two ports to each other.
It is a media converter for 3R supporting 125 M to 1.25 Gbps (Gigabit Ethernet). The LEX1000 Series is equipped with a LEX1012 chassis and LEX1930-00 for conversion of 000BASE-SX and 000BASE-LX, dual-core to single-core, and so forth. It can be inserted into the chassis to check the status, type, version, fiber link status, and alarm of the media converter.
LEX1821-2F
Features
- Media converter supporting 3R (reamplifying, reshaping, retiming) connecting the SFPs of two ports.
- No transfer frame control and frame size control (because of the repeater operation).
- Conforms to 100BASE-FX and 1000BASE-X standards.
- Equipped with LFP (Link Fault Pass-through) function (settings for each port with DIP switches).
- LED display on the front panel.
- Equipped with advanced ECO mode (LED is illuminated every three minutes to reduce power consumption by 10%. DIP switch settable).
- Includes various types of attachable options:
Magnet, rubber foot, PD cabinet fitting, and binding band for preventing disconnection of the adapter cord.
