Arista QSFP-100G-PSM4 Description
The Arista QSFP-100G-PSM4 optical transceiver is engineered to deliver efficient and dependable 100G Ethernet connectivity over parallel single-mode fiber using four 25G NRZ lanes. Operating at a 1310 nm wavelength, it supports transmission distances of up to 500 meters, making it a practical solution for larger data halls where multimode fiber reach is insufficient.
Its compact QSFP28 form factor enables high port density while maintaining low power consumption and thermal stability. Fully tested for interoperability with Arista networking equipment, the PSM4 transceiver provides a scalable and cost-effective alternative to CWDM-based solutions for short-to-medium reach single-mode deployments.
