Electrical TAPs

Copper TAPs


  • Carrier-grade design
  • Fastest switchover time, depending on the Phys in the tapped nodes, our TAP can switch w/0 to drop the link
  • 10/100/1000 and 10/100 models
  • 10/100 TAP is entirely passive and does not influence the live link in any way (whether the TAP is powered or not)
  • POE pass-through
  • 10/100/1000 TAP features a USB interface providing diagnostic information

Cubro offers copper TAPs in 10/100/1000 models as well as passive 10/100 models. The advanced Cubro 10/100/1000 Copper Network TAP is an all-new development based on the latest PHY chips. These devices are PoE transparent across the link ports. The new “B” version of the 10/100/1000 features a USB interface that the user can connect to and retrieve detailed information about every port on the TAP as well as the TAP status itself.

The new “B” version is also able to gather information about the live link connection as well as about the configuration of the link partners (e.g. duplex, mismatch issues, M/S conflicts...). This information can also be retrieved via the USB interface allowing the Cubro TAP to assist the user in finding mistakes in the configuration of the link partners. Finally, depending on the PHY chips used in the tapped nodes the new Cubro 10/100/1000(B) TAP is attached to, the TAP can switch states without dropping the live link at all. This helps in mitigating the issue of link renegotiation of the tapped nodes that can occur with copper TAPs in a fail open scenario.



  • Fastest switchover time, depending on the Phys in the tapped nodes, our TAP can switch w/o to drop the link
  • Smallest footprint - 21 links in one 19” 3RU chassis
  • Best price and performance
  • Flexible power solution 230 AC and 48 V DC
  • Low power design (Green data center)

The major advantage of this concept is easy expansion and installation. Consider a situation where there are 21 single-link electrical TAPs deployed. In this case, 42 power cords would be required and this could easily lead to a tangled mess. Compared to other solutions with separate TAPs, the new FlexTAP has only two power connectors for up to 21 TAPs.

The flexible and easy-to-install solution consists of 4 parts:

  • 10/100/1000 TAP blade
  • 19” 3RU inch chassis
  • Power module (230 V DC or 48 DC)
  • Fan module

Converter TAPs


  • Carrier-grade design
  • Fault transparent
  • Fully passive
  • 1G or 10G
  • SFP or SFP+ output

The Cubro Converter TAP converts traffic from optical Gigabit Ethernet links to an SFP output. With its passive connection to the network, it does not influence the traffic of the optical network link while allowing complete access to the traffic via the copper 1000 B-T monitoring port. Cubro provides a cost-effective, flexible small device that converts the incoming traffic to an additional output port. The Cubro Converter TAPs use SFP or SFP+ modules giving the user maximum flexibility. It is possible to change or add SFPs during operation without interrupting other ports (hot-swap). Moreover, it is possible to use non-vendor specific SFPs: SM, MM, COPPER, CWDM, and/or BiDi in any combination.

The path from the input to the output ports is fault-transparent. If the link on the input port goes down then the output ports follow with a short delay. The path from the input to the output ports is layer 1 to 7 transparent. Any error on the input port will be copied to all output ports.
