multimode (1300nm) or single mode (1300/1550nm) Fiber Optic hub switch

The TC3705 fiber hub offers multimode (1300nm) or single mode (1300/1550nm) and WDM single fiber 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).

Need a LAN link and you only have one fiber -
this unit has a WDM option that will let you send 100BaseT over one single fiber

Applications

The TC3705 10/100 Ethernet Switch Hub is a low cost and flexible bandwidth solution to efficiently handle the heavy traffic of local workgroups - reducing the need of expensive routers that usually cater to the network backbone.

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 or 115/230VAC with an external power cube. Units are standalone or 19" rack mountable. Optical connectors can be SC, ST or FC.
