The miniature miConverter 10/100 and miConverter 10/100 Plus are rate-switching 10/100 UTP copper to 100BASE-FX fiber media converters. The miConverter provides cost-effective fiber connectivity from Ethernet switches to diagnostic equipment, desktop and laptop computers.

They can be powered by a computer's USB port using the optional USB Power Adaptor Cable, which reduces the module's weight and eliminates the need to tether the miConverter to an electrical outlet that provide cost-effective fiber network extension and connectivity.

The UTP port can auto-negotiate by detecting the speed and duplex-mode of the connected device. Upon connection to the UTP device, the UTP port speed adjusts to either 10Mbps or 100Mbps, and the duplex-mode adjusts to either Full-Duplex or Half-Duplex. Auto-crossover enables the connection to workstations (MDI port) or hub/switches (MDI-X port) without requiring a crossover cable.

The 100BASE-FX fiber port operates in Full-Duplex mode. Models are available for single-mode or multimode fiber with ST or SC fiber connectors. Multimode fiber models support distances up to 5km and single-mode fiber models support distances up to 120km. Single-fiber models feature Bi-Directional fiber and support distances up to 40km.

The miConverter 10/100 Plus features DIP-switches for the configuration of the UTP port and four different Link Modes (fault-detection capabilities). The DIP-switches allow manual configuration of the UTP speed and duplex-mode while the Link Modes assist in the identification and isolation of link failures. The available modes are Link Segment, Link Propagate, Remote Fault Detection and Symmetrical Fault Detection.

Diagnostic data is provided through LED indicators that assist in network installation and maintenance. The LEDs report the availability of power, port activity and link status, speed and duplex-modes of the UTP port.

The external AC power supply is available in US, Universal and Country/Region specific models. Country/Region specific models feature optional interchangeable connectors, allowing for compatibility with electrical outlet types found around the world.

The miConverter 10/100 and miConverter 10/100 Plus can be mounted in the miConverter 18-Module Power Chassis to consolidate individual modules into a rack-mount form factor that can be deployed where multiple fiber optic links are distributed from UTP switch equipment. The chassis powers converter modules with barrel-style DC connectors, and is available with a single universal AC, 24VDC or 48VDC internal power supply. This compact, high-density chassis is 1.5 rack units high, and can be mounted in a standard 19” or 23” equipment rack.

The miConverter 10/100 and 10/100 Plus combine reliable Ethernet connectivity with the lightweight design and low power consumption required for both permanent deployment and mobile service networks.

Weighing less than 5 oz. with the USB Power Adapter Cable, the miConverter 10/100 and 10/100 Plus can easily fit into any pocket or laptop carrying case. It can also be attached to portable equipment using the included Velcro® strips or wallmounted using the optional wall-mounting bracket kit.

The application diagram depicts a laptop computer used in a fiber network. The miniature size and low power consumption of the miConverter 10/100 and 10/100 Plus make it the ideal media converter in this scenario.

The miConverter connects to the laptop via two cables. The first cable is the USB Power Adapter which draws electrical current from the laptop's USB (1.0 or 2.0) port to power the miConverter. The other cable is the UTP cable that links the laptop network port and the miConverter copper port. The miConverter converts the UTP signal to fiber signal, which can extend up to 120km. Power from the USB port of the computer is automatically shut off when the computer is powered down, turning off the miConverter when fiber conversion is no longer needed.

The cost-effective miConverter is ideal for connecting large numbers of workstations in unmanaged fiber-to-the-desktop Enterprise network applications. These applications can include remote edge locations where power outlets are at a premium, such as portable, temporary facilities. The miConverter is also an excellent solution for construction and military fiber-to-the-laptop applications where Ethernet fiber connectivity is required and local power is not available.
