Description
The AddOn Arista Networks® QSFP-100G-LR-AR-CW27 Compatible Transceiver is a high-performance, hot-swappable optical module designed for 100GBase-CWDM Ethernet applications. Operating over single-mode fiber (SMF), it delivers up to 10km reach using a 1270nm wavelength via an LC duplex connector. Compliant with QSFP28 and 100G Lambda MSA specifications, this transceiver supports a 4x25G electrical interface and PAM4 modulation for superior data transmission efficiency. Integrated Digital Optical Monitoring (DOM) provides real-time diagnostics for optimal network performance. Fully TAA and RoHS compliant, this module undergoes rigorous testing to guarantee seamless interoperability and identical performance to the original Arista Networks® part. It is ideal for high-speed access, metro, and enterprise networking environments, ensuring reliable, scalable connectivity with power dissipation under 4.5W and a standard operating temperature range of 0°C to 70°C.
