Applications
The primary function of Black Box LH1500 Media Converter is to permit two
different media types to coexist within the same network by allowing data to be
transmitted and received between different media types. Black Box 1500s are typically
used where new 100MB switching hubs with RJ-45 ports are being installed, and where
full-duplex fiber segments (of up to 2Km for multi-mode or 15Km for single mode) are
needed to interconnect them with other 100Mb switching hubs in distant wiring closets.
Alternatively, a server with a full-duplex NIC needs to be connected via fiber to a 100Mb
switching hub with RJ-45 ports. In these and similar situations, the Black Box LH1500
conveniently converts the twisted pair cable to fiber, allowing use of any available RJ-45
Fast Ethernet switched port with a new or existing fiber cable. See Section 3.2.1 for cable
distance calculation information.
