Juniper EX4600

You can nd informaon about the opcal transceivers supported on your Juniper device by using the
Hardware Compability Tool. In addion to transceiver and connecon type, the opcal and cable
characteriscs–where applicable–are documented for each transceiver. The Hardware Compability
Tool enables you to search by product, displaying all the transceivers supported on that device, or
category, by interface speed or type. The list of supported transceivers for the EX4600 is located at
hps://pathnder.juniper.net/hct/product/#prd=EX4600.
CAUTION: The Juniper Networks Technical Assistance Center (JTAC) provides
complete support for Juniper-supplied opcal modules and cables. However, JTAC does
not provide support for third-party opcal modules and cables that are not qualied or
supplied by Juniper Networks. If you face a problem running a Juniper device that uses
third-party opcal modules or cables, JTAC may help you diagnose host-related issues if
the observed issue is not, in the opinion of JTAC, related to the use of the third-party
opcal modules or cables. Your JTAC engineer will likely request that you check the
third-party opcal module or cable and, if required, replace it with an equivalent
Juniper-qualied component.
Use of third-party opcal modules with high-power consumpon (for example,
coherent ZR or ZR+) can potenally cause thermal damage to or reduce the lifespan of
the host equipment. Any damage to the host equipment due to the use of third-party
opcal modules or cables is the users’ responsibility. Juniper Networks will accept no
liability for any damage caused due to such use.
Cable Specicaons for QSFP+ Transceivers on EX4600 Series Switches
The 40-Gigabit Ethernet QSFP+ transceivers that are used in EX Series switches use 12-ribbon
mulmode ber crossover cables with socket MPO/UP, MPO/UPC, or MPO/APC connectors. The ber
can be either OM3 or OM4. These cables are not sold by Juniper Networks.
CAUTION: To maintain agency approvals, use only a properly constructed, shielded
cable.
TIP: Ensure that you order cables with the correct polarity. Vendors refer to these crossover
cables as key up to key up , latch up to latch up , Type B , or Method B . If you are using patch
panels between two QSFP+, ensure that the proper polarity is maintained through the cable
plant.
