EL900-A-B-1-A 10/100BASE-TX to 100BASE-FX Hardened Media Converter (SC, MM)

EL900-A-B-1-A 10/100BASE-TX to 100BASE-FX Hardened Media Converter (SC, MM)

The EtherWAN EL900-A-B-1A 10/100BASE-TX to 100BASE-FX Hardened Media Converter (SC, MM) provides media conversion between 10/100BASE-T and 100BASE-SX Mulitmode Fibre with SC interface. Built specifically for mission-critical applications in harsh environments, the EL900's hardened design features high shock & vibration resistance, electrical noise immunity, wide operating temperature range from -40°C to 75°C, and ruggedized aluminum housing.

With triple power inputs, link down alarming, Link-Fault-Pass-Through, the EtherWAN EL900-A-B-1-A  is the ideal Multimode (MM) SC Fibre Media Converter for harsh environments.

EtherWAN — "When Connectivity is Crucial."
