EL2315 Series

10/100/1000BASE-TX to 100/1000BASE-X Dual Rate SFP Media Converter
UL 60950
Link Fault Pass Through (LFPT)
Dual rate SFP slot
Wall mounting or EtherWAN's EMC1600 chassis for easy group installation with power redundancy

The EL2315 Series provides media conversion between 10/100/1000BASE-T(X) and 100/1000BASE SFP Fiber. The EL2315’s fiber design is compatible to 100BASE fiber or 1000BASE fiber transceiver. Through DIP switch selection, the EL2315’s SFP port can support 100BASE SFP fiber or 1000BASE-X SFP fiber port. Also, through DIP switch selection, the Link-Fault-Pass-Through (LFPT) function can be active or disabled.

With Gigabit transmission rate, EL2315 supports Jumbo Frame up to 9K bytes, the EL2315 is the ideal media converter for environments where connectivity is crucial.

EtherWAN — "When Connectivity is Crucial."

Gigabit Connectivity

    • Auto 10/100/1000BASE-T(X) and 1000BASE-SX/LX/BX Ethernet transmission conversion
    • 1000Mbps Full duplex, 10/100MBps Full/Half duplex
    • Fiber interface supports dual rate 100BASE-FX and 1000BASE-SX/LX fiber transmission

Link-Fault-Pass-Through (LFPT)

    • Provides constant monitoring of the links connected to the media converters
    • If a copper links fails, the media converter will pass the fail state on throughout the link, disabling the fiber link and the copper link on the opposite end
