Fault-tolerant, copper or optical, full-duplex TAPs maximize visibility and minimize link downtime on switched LANs and SANs. Finisar TAPs provide access to all network traffic from both sides of a full-duplex link at line rate. Completely invisible and non-intrusive to the network, TAPs allow for monitoring, capturing, and analyzing physical errors, timing errors, and client-server interactions. Finisar TAPs are available in either copper 10/100 (Shadow TAP) or optical (High Density TAP).
