Media Converters Installation and User Guide (01/02)

Black Box Media Converters have an external power supply, enabling them to

be used to convert signals among media that does not have a power source as part of the

cabling system, such as twisted pair, BNC and Fiber. (AUI port can supply power).

2.5 Full / half-duplex applications.

Of the various 10Mb media types, only the twisted-pair to fiber combination is

capable of full-duplex (i.e., simultaneously transmitting and receiving on the same cable

segment) operation. Full-duplex is rarely required at 10Mb, but might occasionally be

desired to connect a 10Mb RJ-45 switch port over a fiber link to a full-duplex RJ-45 NIC

in a remote server, or to connect to another full-duplex 10Mb RJ-45 switch port.

The various LB1502A units tagged FULL/HALF DUPLEX operate

transparently to the simultaneous TX / RX condition, and do not indicate Collisions or

Jabber even if they are present. They are suitable for all normal half- and full-duplex

applications
