Cisco BiDi technology makes 40Gb connectivity more cost effective by using bidirectional optics over traditional multimode fiber links used for 1Gb and 10Gb. These BiDi links require special taps.Gigamon’s BiDi taps export monitored traffic gathered from across all four transmit signals, providing complete, and cost-effective coverage for analytic and security tools.
The G-TAP BiDi solution includes a purpose-built passive BiDi TAP combined with a pair of receive-only (RX-only) BiDi transceivers to protect the network, helping to ensure monitored traffic can never be introduced back into the production network. Monitored BiDi traffic is channeled directly into the Gigamon Visibility Platform to be combined with other traffic sourced from across the network. Gigamon’s patented Flow Mapping® technology filters, aggregates, and disperses the right information to the right tools anywhere across the fabric. Advanced intelligence offers deep packet inspection providing a variety of services from De-duplication to NetFlow Generation. The G-TAP M Series BiDi module taps 4 BiDi links—that’s up to 24 BiDi links in a 1 RU chassis. The Rx-only BiDi QSFP+ is compatible with all 40Gb ports on the Visibility Appliances.
