Product Description

Terminating a fiber run while using various local, copper-based devices such as PCs, printers, VoIP, etc. is essential for the success of Fiber-to-the Business, Curb and other FTTx projects. Remote locations have similar configuration demands. Connecting the multiple copper devices to the fiber, however, typically requires the use of both a media converter and a switch— two pieces of equipment to purchase and two pieces of equipment to monitor and maintain. The AccessConverter streamlines FTTx projects as well as the connection of remote locations as a multi-port, switching media converter.

Best of all, one compact AccessConverter module reduces the amount of required equipment while providing all the features of a switch (store and forward switching mechanics, MAC address learning, protection against broadcast storms, flow control, etc.) and performing the electrical-to-optical conversion. In addition, the unit’s small size and wall-mount bracket (included) allow you to install AccessConverter virtually anywhere, including inside a network interface device (NID).

Requiring no configuration, the AccessConverter offers plug-andplay

  • Each copper port auto-senses the connected device’s speed and duplex mode (10 Mbps or 100 Mbps and HDX or FDX) and includes AutoCross, a feature which automatically selects between a crossover workstation (MDIX) or pass-through (MDI)connection depending on the connected device
  • The fiber port always operates at 100 Mbps FDX, and supports distances up to 80 km; single-strand fiber versions are available.
