Ethernet to Fiber Optic Media Converter

Ethernet to Fiber Optic Media Converter

Media Converter ( Ethernet to Fiber Optic Converter ) : The SMC-40-FE is a rugged, industrial-grade 10/100M Ethernet to fiber optic media converter, which provides one channel for media conversion between 10/100BaseTX and 100BaseFX. It supports either multi-mode or single-mode fiber optic and MDI (straight-through) and MDIX (crossover) cables, therefore, no DIP switch, jumper settings or software drivers are required, making the unit a highly reliable and truly plug-and-play device. It features auto-negotiation for half or full-duplex and 10 or 100Mbps data rates,  Besides the capability of long distance data transmission and the large carrying capacity, fiber lines are inherently resistant to EMI / RFI, lightning, transient surges and ground loops; therefore, they are ideal for data communications surrounded by heavy electrical or radio interference.

Category: .

It comes with ST/SC/FC connectors for fiber optic links and can extend the 10 / 100M Ethernet distance to 2km for multi-mode and 20 to 120km for single-mode. The product can be mounted directly on a wall, panel or DIN Rail, without a need of additional brackets. It has inbuilt power supply module, therefore, no need for using external power adapter.
