Cisco BiDi is a technology that provides data centers with a 10Gbit infrastructure an economical path to 40Gbit and even 100Gbit speeds. Cisco BiDi technology uses the existing 10G cabling plant of duplex OM3 or OM4 fiber, unlike the competing standards of SR4 and CSR4 which require a complete overhaul of cabling and connectors. With this technology, an upgrade to 40G or even 100G only requires new transceiver and some changes to the visibility layer. Due to the nature of BiDi, traditional TAPs will not work and need to be replaced with BiDi specific models. This is not a major disadvantage, however, as migration to SR4 or CSR4 based 40/100G would require completely new network TAPs as well.
The Cisco 40G&100G bidirectional (BiDi) concept is a smart way of using existing optical multimode infrastructure that was originally planned for 10Gbit links only. By making use of the two separate wavelengths on a single fiber and advanced optical modulation methods the upgrade to 40G or 100G of an existing multimode cable plant becomes straight-forward.
To tap such a BiDi link is challenging because traffic is flowing at two different wavelengths on the same fiber.
The Cubro 40&100Gbit BiDi TAP addresses this visibility challenge by providing a cost-effective solution when tapping Cisco BiDi 40 Gbit links or 100 Gbit links is required. This TAP allows getting easy access to traffic flowing on Cisco BiDi links without interfering with live data transfer.
The Cubro BiDi TAP is fully passive, completely traffic transparent, features low insertion loss, adds no delay to live traffic and works for both 40Gbit as well as 100Gbit. The TAP is available as 1 link or 2 links version and requires only 1/3 of a U in a 19” rack.
The tapped BiDi traffic can be further processed to enhance visibility by using it with a Cubro Advanced Packet Broker such as the powerful EXA32100.
The EXA32100 Advanced Packet Broker is the perfect tool to terminate and further process the traffic coming from the 40&100Gbit BiDi TAP. It features 32 x 40/100G QSFP/QSFP28 ports that are fully compatible with Cisco 40Gb and 40&100Gb transceivers. The advanced network packet broker aggregates, filters or load balances the BiDi traffic before sending it to the relevant tools. The advanced capability of the EXA32100 technology allows performing sophisticated applications like filtering out an individual IP stream inside a Cisco BiDi link or distributing traffic to different 10Gb monitoring tools.
