LEX3851-1F
Media Converter for Ethernet OAM
LEX3851-1F is the world’s smallest*1 Ethernet OAM compatible 10/100/1000BASE-T to 100BASE-FX/1000BASE-X (SFP) media converter.
- Is the world’s smallest Ethernet OAM compatible Giga media converter.
- The optical module utilizes SFP and supports 100BASE-FX, 1000BASE-SX, SX2, LX and ZX. It can also be used with single fiber type (BiDi/BX) or CWDM SFP.
- Switch operated and jumbo frame compatible.
- LED-verifiable signal detection function.
- Instant power-off notification function (Dying Gasp).
- Fanless design. Made in Japan – Japanese quality.
*1 Among stand-alone Ethernet OAM compatible Giga media converters,
according to FXC’s findings as of April 18, 2018.
LEX3851-1F
Features
- A media converter capable of converting 10BASE-T, 100BASE-T and 1000BASE-T ports into 100BASE-FX and 1000 BASE-SX/SX2/LX/ZX ports.
- Can be built into a chassis or used as a stand-alone device. *Chassis will be released at the beginning of July 2018.
- Includes Ethernet OAM function (continuity check by Ethernet frame transmission and reception).
-IEEE 802.3ah (adjacent node: Link DAM): Discovery, Link Monitor, RFI, Dying Gasp
