FastJackTM Single Port
10BASE-T RJ-45 Connectors
HALO is pleased to offer this complete range of single port Integrated RJ-45 connectors.
The FastJackTM series integrates the high performance of HALO magnetics into an in-
dustry standard connector design. The result is an extremely robust, IEEE802.3 compli-
ant, solution. Single and multi-port FastJacksTM are available for most 10BASE-T and
10/100BASE-TX IC's.
