100GbE High-Speed Connectivity
The XVR-10068-21 provides 100Gbps Ethernet connectivity for high-bandwidth network environments. Its 100GBASE-LR4 architecture is designed for applications requiring significantly more bandwidth than 10GbE, 25GbE and 40GbE connections.
It is suitable for high-performance data center networks, aggregation links, core networking and interconnection between network infrastructure located up to 10km apart when the appropriate optical infrastructure is used.
100GBASE-LR4 Optical Standard
The XVR-10068-21 uses the 100GBASE-LR4 optical standard. Arista identifies 100GBASE-LR4 as a 100G optical QSFP technology supporting up to 10km over 9µm single-mode fiber. :contentReference[oaicite:4]{index=4}
LR4 is intended for long-reach 100GbE connectivity compared with shorter-reach multimode optics such as 100GBASE-SR4.
10km Transmission Distance
The XVR-10068-21 supports transmission distances of up to 10km over duplex single-mode fiber. :contentReference[oaicite:5]{index=5}
This makes the transceiver suitable for connecting network switches across different data center areas, buildings, campuses or other locations where the fiber path is within the supported optical budget.
Single-Mode Fiber Support
The XVR-10068-21 is designed for 9µm single-mode fiber (SMF). Arista's transceiver catalog specifies 9µm SMF for 100GBASE-LR4 with a 10km reach. :contentReference[oaicite:6]{index=6}
Single-mode fiber is appropriate for long-distance optical networking and provides substantially greater reach than typical multimode-fiber solutions.
QSFP28 Form Factor
The QSFP28 form factor is widely used for 100GbE optical networking. It provides a compact pluggable interface suitable for high-density data center switch deployments.
Before installation, confirm that the target Arista switch or network device supports the specific XVR-10068-21 optic and the required 100GBASE-LR4 configuration.
Duplex LC Connectivity
The XVR-10068-21 uses a duplex LC optical connection for the single-mode fiber link. A compatible duplex LC single-mode fiber cable is required for a standard point-to-point connection.
Data Center Interconnect
The 10km reach of 100GBASE-LR4 makes the XVR-10068-21 suitable for data center interconnect applications where high bandwidth is required between network locations.
It can be deployed for connections between leaf and spine infrastructure, aggregation layers, core switches and other compatible 100GbE networking equipment.
Arista Network Compatibility
Arista's documentation lists 100GBASE-LR4 among the supported optics for multiple 100G QSFP platforms. For example, Arista's 7170 Series documentation lists 100GBASE-LR4 with a 10km single-mode duplex reach, while the 7368X4 and 7500R documentation also list 100GBASE-LR4 as a supported 100G optical type. :contentReference[oaicite:7]{index=7}
Actual optic support depends on the exact Arista switch model and EOS release. Always check the appropriate Arista transceiver compatibility documentation before deployment.
Long-Distance 100GbE Networking
Compared with short-reach 100G optics designed for multimode fiber, LR4 provides a significantly longer optical reach. This makes it suitable for network infrastructure where the endpoints cannot be connected using short multimode fiber runs.
High-Bandwidth Network Applications
The XVR-10068-21 is suitable for high-bandwidth applications such as data center aggregation, spine-leaf networking, storage networking, cloud infrastructure and enterprise core links.
- 100GbE uplinks
- Data center spine links
- Leaf-to-spine connectivity
- Core network connections
- Data center interconnects
- Cloud infrastructure
- Storage network infrastructure
- Enterprise network aggregation
