Analog Passthrough Adapters
Analog Passthrough Adapters for SFP Connectors
Xgig1000 chassis with 25 Gbps and 32 Gbps SFP ports are shipped with the appropriate
number of analog passthrough (APT) adapters (
Figure 28 }. This adapter acts as a
passthrough tap for both optical and electrical (copper) links.
• The Xgig1000 25G/32G 4-port chassis is shipped with 2 APT adapters.
• The Xgig1000 25G/32G 8-port chassis and the Xgig1000 25G/32G/50G/100G/128G
10-port chassis are shipped with four APT adapters.
Each adapter is designed to be inserted into two adjacent ports (e.g., ports 1-2 or 3-4 on
chassis with four SFP ports and ports 1-2, 3-4, 5-6, or 7-8 on chassis with eight SFP ports).
See
Figure 31 on page 140 .
Figure 28 Analog Passthrough Adapter for SFP Ports
The bidirectional APT adapter supports analog pass-through mode through an external
adapter with a SFP28 for 25GE and SFP+ for 32G FC interfaces. This external adapter is
a passive adapter meaning that it has no external power supply.
A bracket is also supplied with the chassis which is used to support the APT adapters at
the front of the chassis. In addition to supporting the adapters on the shelf-like bracket,
thumbscrews secure the adapters to the bracket. Refer to
Figure 30 .
