Product Condition & Key Features
This is a genuine Arista QSFP-100G-LR4 100GBASE-LR4 Single-Mode Optical Transceiver Module (SKU: XVR-10068-20) in excellent, fully tested working condition. Pulled from an operational Arista switch cluster, the optic has been verified to establish stable links, transmit cleanly over fiber, and display full DOM telemetry diagnostics.
- 100GBASE-LR4 Standard: Operates at 100 Gbps by multiplexing 4x 25 Gbps LAN-WDM lanes onto a single pair of LC single-mode fibers.
- 10 Kilometer Optical Reach: Long-reach design supports signal transmission distances up to 10 km (6.2 miles) over standard G.652 Single-Mode Fiber (SMF).
- Digital Optical Monitoring (DOM): Supports real-time diagnostic reporting including optical Rx/Tx power levels, temperature, and supply voltage.
- Arista Native Coding: Programmed with native Arista firmware codes (XVR-10068-20) to prevent port-override or unsupported transceiver warnings in Arista EOS.

Important Cabling & Optics Warnings
Single-Mode Fiber Only: This transceiver is designed **strictly for Single-Mode Fiber (SMF) cabling with LC Duplex connectors**. It will **NOT** link or work over Multi-Mode Fiber (MMF) cables (like OM3 or OM4). Please check your patch cable types before purchasing.
Receive Saturation Warning (Short-Range Links): Engineered to drive up to a 10 km reach. If configuring short links (e.g. inside a test lab rack under 100 meters), you may need to install fiber attenuators to avoid overpowering and permanently damaging the PIN receive photodiode array.
Firmware Coding: Programmed with genuine Arista EOS vendor identity profiles. It is compatible with Arista QSFP28 switch and router optical interfaces.
