Compatible Optics for Juniper QFX5200-64Q Switch

Designed to meet advanced data forwarding and network monitoring needs, Juniper QFX5200 switches are ideally suited for leaf deployments in next-generation IP fabric networks. QFX5200-32C and QFX5200-64Q are two common switches among QFX5200 series, they are featured as extra low latency, high flexibility, cost-effective and high density. If you are looking for such a switch with more QSFP+ and QSFP28 ports, QFX5200-64Q is a good option. The detailed information about QFX5200-64Q will be fulled covered in this passage.

Overview on QFX5200-64Q

QFX5200-64Q offers 32ports of 100GbE or 64 ports of 40GbE, and delivering 3.2Tbps line-rate switching performance with latency as low as 500 ns. A QSFP28 module can be used for a 1×100GbE connection or 2×50GbE or 4×25GbE connections using breakout cables. A QSFP+ module can be used for a 1×40GbE connection or 4×10GbE connections using breakout cables. Both the two versions support 128 10GbE SFP+ through QSFP+ to SFP+ breakout cable and 128 25GbE SFP28 through QSFP28 to SFP28 breakout cable. The front view and main features of QFX5200-64Q are just in the below:

  • Flexible connectivity options
    The QFX5200 offers a choice of 10GbE, 25GbE, 40GbE, 50GbE, and 100GbE interface speeds for server and intra-fabric connectivity on both platforms, providing deployment versatility and investment protection.
  • High density configurations
    QFX5200 switches are optimized for high-density fabric deployments.
  • Rich automation capabilities
    The QFX5200 switches support Python, Chef, Puppet, and Zero Touch Provisioning (ZTP).
  • High availability
    Topology-independent in-service software upgrade (TISSU) and fast reboot ensure high network availability during a switch update.
Compatible Optical Transceivers for QFX5200-64Q

As we can see from the below table, there are many types of optical transceivers supporting QFX5200-64Q. For QSFP+ port, you can choose QFX-QSFP-40G SR4 and QFX-QSFP-40G LR4 for transferring data over short and long distance respectively. You can use QFX-QSFP-40G SR4 modules for short transmission distance on this switch. Just plug the QFX-QSFP-40G SR4 into the QSFP+ port on QFX5200-64Q, the signals can be arrived up to 150 m. If this transmission distance cannot meet your requirement, 40GBASE-LR4 QSFP+ is a perfect choice. Just press firmly with your thumb and push the 40GBASE-LR4 QSFP+ transceiver gently to the transceiver socket on the switch, the maximum transmission distance on this switch can be up to 10 km.

For QSFP28 ports, you can also use JNP-QSFP-100G-SR4 and JNP-QSFP-100G-LR4 for short and long haul transmission. Using QSFP28 Juniper JNP-QSFP-100G-SR4 compatible transceiver on the QFX5200-64Q switch, the information can be transmitted over 100 m. By plugging the 100G QSFP28 LR4 module into the QSFP+ ports on the switch, the signals can be transmitted as far as 10 km. All of the modules in the above table are 100% tested, they are fully compatible to the QFX5200-64Q.

Compatible DAC Cables for QFX5200-64Q

From the above statement, we are clear that the Juniper QFX5200-64Q switch has 64 QSFP+ ports, so you can directly connect the two ends of the DAC cable to the corresponding port on the switch. The following table shows the detailed information about compatible DAC cables for QFX5200-64Q. For transmission distance over short distance, you can choose 40G QSFP+ DAC cables to make network connectivity. By using 40G breakout cable, you can just plug the one end of 40G QSFP+ copper direct attach cable into the 40G QSFP+ ports and plug the other ends of the DAC cable into four 10G SFP+ ports.

Besides, you can also connect the two ends of 40G DAC cable with the 40G QSFP+ ports directly to make connectivity on the Juniper QFX5200-64Q switch. When the transmission distance is longer, 40G QSFP+ AOC cable is a good option to transfer data. Like the 40G QSFP+ DAC cable, you can plug the two ends of 40G QSFP+ AOC cable into the QSFP+ ports on the Juniper QFX5200-64Q switch. Those 40G QSFP+ DAC and AOC cables are suitable for short distance and ideal for high cost-effective connectivity to your Juniper QFX5200-64Q switch.


The Juniper QFX5200-64Q switch offers flexible, cost effective, high-density 10GbE, 40GbE and 100GbE interfaces for server and intra-fabric connectivity, providing deployment versatility, investment protection, and future protection for today’s data centers.
