Frequently Asked Questions

What is the primary transmission distance supported by the Arista QSFP-100G-DR transceiver? +

The Arista QSFP-100G-DR is designed for high-speed connectivity over single-mode fiber, specifically optimized for reaches up to 500 meters. This makes it an ideal choice for data center interconnects and high-density leaf-spine architectures where short-range, high-bandwidth communication between switches is required within a facility.

Does the QSFP-100G-DR module support 100GBASE-DR interoperability with other vendor equipment? +

Yes, the QSFP-100G-DR adheres to standardized IEEE 802.3cu specifications. This ensures full interoperability with other networking hardware that supports the 100GBASE-DR standard. As long as the target device is compliant with standard 100G PAM4 signaling and the appropriate single-mode cabling, you can expect seamless integration into your existing Arista or multi-vendor switching environment.

What type of optical interface does the Arista QSFP-100G-DR utilize? +

This module features an MPO-12 optical connector interface. It utilizes 1310nm wavelength technology to provide a reliable 100G link. When deploying this transceiver, ensure that your cabling infrastructure is prepared for MPO connectivity, which allows for efficient high-density fiber management in modern rack environments.

Is the Arista QSFP-100G-DR compatible with all Arista 100G switches? +

Compatibility depends on the specific hardware platform and the supported software version. Generally, this module is compatible with most Arista fixed and modular switches that feature QSFP28 ports capable of supporting 100G-DR optics. We recommend verifying the module against your specific switch's hardware compatibility list (HCL) to confirm that the port speed and power consumption requirements are fully satisfied.

What kind of cabling is required for the QSFP-100G-DR transceiver? +

This transceiver is specifically designed for use with single-mode fiber (SMF) cabling. Because it utilizes 100GBASE-DR standards, users should deploy OS2 single-mode fiber to ensure optimal signal integrity and reach. Always inspect fiber end-faces before installation to prevent contamination, which can impact performance at these high-speed transmission levels.

How does the QSFP-100G-DR manage thermal performance in high-density environments? +

The module is engineered to operate within specified thermal envelopes common in enterprise data centers. Its internal architecture is optimized to manage the heat dissipation associated with 100G PAM4 transmission. For the best reliability, ensure your switches have adequate airflow and that all empty ports are filled with blanking panels to maintain proper internal chassis pressure and cooling efficiency.

Does the Arista QSFP-100G-DR require specific software configuration? +

In most Arista EOS deployments, the switch will automatically detect the transceiver once it is inserted into the QSFP28 port. While plug-and-play functionality is standard, you may need to verify that the port is administratively enabled and configured for 100G operation. Consult your switch command-line interface documentation if the link status does not immediately transition to active.

Can the QSFP-100G-DR be used for breakout applications? +

The QSFP-100G-DR is primarily designed for point-to-point 100G connections. While breakout configurations depend heavily on switch port capabilities and internal logic, standard 100G-DR optics are typically used for high-bandwidth uplinks rather than channelized breakout scenarios. Please check your switch’s specific configuration guide to see if it supports sub-rate multiplexing or port-splitting with this particular optical transceiver.

How can I request a bulk quote for multiple Arista QSFP-100G-DR modules? +
