Your JTAC engineer might recommend that you check the third-party optic
or cable and potentially replace it with an equivalent Juniper Networks optic
or cable that is qualified for the device.

The cables are hot-removable and hot-insertable. A breakout cable consists of a QSFP+
transceiver on one end and four SFP+ transceivers on the other end. The QSFP+
transceiver connects directly into the QSFP+ access port on the ACX5000 routers. The
cables use high-performance integrated duplex serial data links for bidirectional
communication on four links simultaneously. The SFP+ links are designed for data rates
up to 10 Gbps each. Passive breakout cables have no signal amplification built into the
cable assembly. There are two types of DAC cables:
Passive DAC cables have no signal amplification built into the cable assembly.
