Route Ethernet signals through hostile RFI/EMI environments and extend distances up to 1.2 miles (2 km) with multi-mode fiber, up to 12.4 miles (20 km) with single-mode fiber. B&B Electronics offers a series of Ethernet media converters in a rugged industrial DIN rail mount package with extended voltage and temperature specifications (EIR series).

B&B Electronics also offers affordable models in a desk, wall, or rack mountable package that include a power supply (EIS series). These models share similar features to the rugged series except for the voltage and temperature specifications. Each product family comes with options to convert 10/100BaseTX signals to 100BaseFX either with multi-mode or single mode fiber. Your choice of ST or SC connectors with multi-mode versions, single-mode products come with SC connectors.

Users have great flexibility with enhanced features such as auto negotiation and forced modes for full or half-duplex and 10 or 100 Mbps data rates. Link-fault-pass-through can also be enabled and disabled via a dip switch setting. The link-fault-pass-through feature allows the network manager to react to a broken link as soon as one occurs.
