Featuring distances up to 80km, the TC3705 10/100Base-T Ethernet Fiber Optic Switch provides a 100Base-FX port that combines Ethernet Switching and Fiber Optic technology to boost total network bandwidth.
The TC3705 offers one multimode (1300nm) or single mode (1300/1550nm) optical port and four Ethernet 10/100Base-T Auto-Sensing switched ports. Each of these ports supports either 10Base-T or 100Base-T. There are two optional versions (Model TC3705T) for extreme temperature applications (-20C to 70C, -40C to 80C).
Because it functions like an Ethernet bridge (connects multiple Ethernet segments to prevent unnecessary network traffic), it creates an efficient sub-divided switched LAN that provides full and transparent bandwidth for each segment.
The TC3705's modern switching technology eliminates the congestion problem inherent to the contention-oriented Ethernet CSMA/CD protocol. This improves predictable response times under heavy network loads. Previously, expensive routing technology was used to alleviate congestion from heavy traffic loads. Power is 12VDC, optional 24Vdc, -48Vdc, 125Vdc or 115/230VAC with an external power cube. The TC3705S is the standalone/wallmount unit. The TC3705R rackmount version fits into the TCRM192 or TCRM196 19" rackmount card cages. Optical connectors can be SC, ST or FC.
