Quad Analog Passthrough (QAPT) Adapter for QSFP Connectors
The Xgig1000 10 Port 25G/32G/50G/100G/128G chassis supports the Quad Analog
Passthrough (QAPT) adapter (
Figure 29 } that plugs into its two front-panel QSFP ports.
This QAPT adapter acts as a passthrough tap for both electrical (copper) and optical links
for the 50GigE, 100GigE, and 128G FC protocols.
For electrical (copper) links, insert the cable connectors directly into the QAPT connectors.
For optical links, insert the optical QSFP transceivers into the QAPT connectors. These
QSPF transceivers are specialized and are available by ordering the QSFP K-Kit from
Viavi. Each K-kit includes two optical QSFP transceivers and two optical cables. You need
to order Viavi part number 22110920 (which has the following description: XGIG1K-10002-
MM;100GE/128G FC QSFP28 K-Kit Includes SFP28 and MM Cables).
Figure 29 QAPT Adapter
The bidirectional QAPT adapter supports analog pass-through mode for 50GigE,
100GigE, and 128G FC interfaces. The QAPT 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 QAPT adapter at
the front of the chassis. In addition to supporting the QAPT adapters on the shelf-like
bracket, thumbscrews secure the adapters to the bracket. Refer to
Figure 30 .
CAUTION
To protect the adapter from damage, keep the plastic covers in place on the adapter’s
two QSFP arms until you are ready to plug the adapter into the two adjacent QSFP
ports on the front panel of the chassis.
