EKI-2741LX - 1 Port Gigabit Ethernet to 1000Base-LX Fibre Industrial Media Converter

5 Year Warranty

These products come with a standard five year manufacturer warranty.

Extended Wide Temperature

These products utilise high quality industrial grade components enabling them to work in extended wide temperature environments. They are capable of running below -20C and above +70C and offer further protection than standard wide temperature rated products.

Wide Temperature

These products utilise high quality industrial grade components enabling them to work in wide temperature environments. They are capable of running as low as -20C and as high as +70C.

Wide Voltage

These devices and systems have been designed to accept a wide voltage DC power input. This feature is desirable in the industrial market where a fixed voltage level or mains AC power cannot be guaranteed.

DIN-rail mountable

These devices have been designed to be mounted directly on to an industry standard DIN-rail.

The EKI-2741LX  is an industrial-grade media converter designed to convert a copper TX Ethernet network to a SC type fibre optic network.

The advantage to fibre optics is wider bandwidth, added EMI immunity, and extended distance transmission. Therefore the EKI-2741LX  is an ideal solution for “fibre-to-the-building” applications in central offices and remote sites.

The EKI-2741LX supports MDI/MDIX auto detection, meaning you no longer have to use crossover wires. Furthermore, the EKI-2741LX will operate in a wide -10°C to +60°C or extended -40°C to +75°C operating temperature range and can accept a wide 12V to 48V DC input. In addition, the EKI-2741LX is designed with 3,000V DC surge (EFT) protection against over-voltage, meaning the media converter is ideal for the harsh industrial environment.

Aside from its standard features, the versatile EKI-2741LX also has the LFP (Link Fault Pass-through) feature. When one side of the link fails, the other side continues transmitting packets, and waiting for a response that never arrives from the disconnected side. EKI-2741LX will force the link to shut down as soon as noticed that the other link has failed, giving the application software a chance to react to the situation.

The EKI-2741LX  is available to purchase directly from Impulse as an approved Advantech partner. For more information about the EKI-2741LX  Ethernet to fibre media converter please contact our technical sales team on +44 (0)1782 337 800, or alternatively submit an enquiry.
