Model TC3715   .10/100 Industrial Ethernet Fiber Optic Switch w/Optional Bandwidth Control          6Tx + 2Fx Ports, 2-fiber strands         6Tx + 2Fx Ports, 1-fiber strand (WDM) Features  Product or Application Questions (click here) 6 Ethernet 10/100Base-T Auto-Sensing UTP Ports 1 or 2 Fiber Optic 100Base-FX Ports Optional 1-Fiber/WDM Version Optional Rate Limiting on Each Port Distances up to 80km Multimode or Single Mode (1300/1550nm) Full or Half-Duplex Operation Industrial Hardened, -40C to 80C (optional) Exceeds Pertinent NEMA & Caltrans Traffic Control Specifications 19" Rack Mount or Standalone   Description Featuring distances up to 80km, the TC3715 10/100Base-T Industrial Ethernet Fiber Optic Switch provides a 100Base-FX port that combines Ethernet Switching and Fiber Optic technology to boost total network bandwidth. The TC3715 offers one or two multimode (1300nm) or single mode (1300/1550nm) optical ports and six Ethernet 10/100Base-T Auto-Sensing switched ports. Each of these ports supports either 10Base-T or 100Base-T. A two-way "one fiber" single mode version is available. There are two optional versions (Model TC3715Q/Y) for extreme temperature applications (-20C to 70C, -40C to 80C). Optional Bandwidth Control gives users, especially data service providers, the ability to control or limit bandwidth. Data rates for Bandwidth Control can be set at none, 128K, 256K, 512K, 1M, 2M, 4M, 8M, 16M, 32M and 64M. It can be managed through any Web Browser, Telnet or Serial Console. Password protection is provided. 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 TC3715'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. Units are 19" rack mountable. Optical connectors can be SC, ST or FC.
