Product Description
The Arista SFP-10G-DW-31.90 is a high-performance SFP+ (Small Form-factor Pluggable Plus) optical transceiver engineered for 10 Gigabit Ethernet applications requiring extended reach. It supports data rates of 10Gb/s and is designed for transmission over single-mode fiber (SMF) up to a distance of 40km. The module operates at a wavelength of 1550nm, which is optimized for long-haul optical transmission, minimizing signal loss and dispersion. This transceiver features a duplex LC connector, providing a standard and secure physical interface for optical fiber connections. Its SFP+ form factor ensures compatibility with a wide range of network switches, routers, and other networking equipment that support SFP+ interfaces. The hot-pluggable nature of the SFP+ module allows for easy installation and replacement without the need to power down the host device, facilitating network maintenance and upgrades. The SFP-10G-DW-31.90 is ideal for building robust metro and long-reach networks. It typically includes Digital Diagnostic Monitoring (DDM) capabilities, allowing network administrators to monitor real-time operational parameters such as optical transmit and receive power, temperature, and voltage. This feature is crucial for performance monitoring, fault detection, and proactive network management.
