Frequently Asked Questions
What is the maximum transmission distance for the Arista QSFP-100G-PSM4 transceiver? +
The Arista QSFP-100G-PSM4 is designed for high-density, short-reach data center applications. It supports link lengths of up to 500 meters over parallel single-mode fiber (PSM4) cabling. This makes it an ideal solution for interconnecting switches within a row or between adjacent rows in large-scale enterprise data center environments.
Does the QSFP-100G-PSM4 require specific fiber optic cabling? +
Yes, this transceiver utilizes an MPO-12 connector interface. You must use single-mode fiber (SMF) with an MPO/MTP connector to ensure signal integrity. Because it uses parallel optics, it transmits and receives data across eight of the twelve available fibers within the ribbon cable, providing a high-bandwidth 100G connection over the PSM4 standard.
Is the Arista QSFP-100G-PSM4 compatible with 10GbE breakout configurations? +
While the QSFP-100G-PSM4 is primarily used for 100GbE to 100GbE point-to-point links, its parallel optics architecture allows it to support 4x25GbE breakout scenarios. This capability provides significant flexibility for network architects looking to aggregate multiple 25G server connections into a single high-speed QSFP28 switch port using the appropriate MPO-to-LC breakout cables.
How does the QSFP-100G-PSM4 differ from a QSFP-100G-CWDM4 module? +
The primary difference lies in the transmission technology and fiber requirements. The PSM4 module uses parallel single-mode fiber, requiring an MPO interface and 12-fiber ribbon cable. In contrast, CWDM4 uses Wavelength Division Multiplexing to transmit 100G over a standard duplex LC single-mode fiber pair. Your choice should depend on your existing fiber plant infrastructure.
What type of switch ports can host the Arista QSFP-100G-PSM4? +
This module is designed for standard QSFP28 ports found on Arista 7000 series switches and other industry-standard networking hardware. Ensure your switch hardware supports 100GBASE-PSM4 protocols. When installing, verify that your switch firmware is updated to recognize the transceiver type to ensure seamless plug-and-play operation within your network fabric.
What is the power consumption profile for this 100G transceiver? +
The QSFP-100G-PSM4 is engineered for energy efficiency, adhering to the power constraints typically associated with QSFP28 form factors. In most enterprise deployments, it operates well within the thermal and power budget of standard line cards. For high-density deployments, it is recommended to monitor your switch's power supply capacity to maintain optimal environmental conditions in your racks.
Is the Arista QSFP-100G-PSM4 hot-swappable during operation? +
Yes, this transceiver is fully hot-swappable, allowing you to insert or remove the module from a powered-on QSFP28 port without interrupting the operation of other ports or requiring a complete switch reboot. This feature is essential for maintaining high availability and performing routine maintenance or hardware upgrades in live production networking environments.
What are the common deployment scenarios for this PSM4 transceiver? +
This module is most frequently deployed in spine-leaf data center architectures where high-speed, parallel connectivity is required for inter-switch links. It is also an excellent choice for connecting high-performance computing clusters that require consistent 100G throughput over distances where standard multi-mode fiber would fall short, providing a reliable, cost-effective upgrade path for your existing optical network.
