Frequently Asked Questions
What is a 40GBASE-SWDM4 QSFP+ transceiver used for?
A 40GBASE-SWDM4 QSFP+ transceiver enables 40 Gigabit Ethernet connectivity over multimode fiber. It's commonly deployed in data centers, enterprise networks, and campus environments where high-speed, cost-effective optical links are required for switch-to-switch or server-to-switch connections within 100-meter distances.
Is the ENET QSFP-40G-SWDM4-AR-ENC compatible with Arista switches?
Yes, this module is functionally identical to the Arista QSFP-40G-SWDM4-AR and fully compatible with Arista switches and platforms supporting 40GBASE-SWDM4 optics. It provides OEM-equivalent performance at a lower cost.
What does DOM (Digital Optical Monitoring) provide?
DOM enables real-time monitoring of optical parameters including transmit/receive power, temperature, and voltage. This allows network administrators to diagnose link issues, predict module failures, and optimize network performance without manual testing.
Can this 850nm transceiver work over single-mode fiber?
No, this module is designed exclusively for multimode fiber (MMF) at 850nm. Single-mode fiber requires different wavelengths (typically 1310nm or 1550nm). Using this transceiver on single-mode fiber will result in signal loss and link failure.
