Product Description
The Arista SFP-10G-DW-42.94 is a high-performance 10 Gigabit Ethernet SFP+ transceiver module designed for demanding network applications. It leverages single-mode fiber (SMF) to achieve extended reach, making it suitable for long-haul connections within data centers or between geographically dispersed locations. The 'DW' in the part number typically indicates support for Dense Wavelength Division Multiplexing (DWDM) systems, allowing multiple channels to be transmitted over a single fiber strand. This transceiver supports a data rate of 10Gb/s and can transmit signals over distances of up to 40 kilometers. The specific channel designation '42.94' likely refers to its position within a DWDM grid, corresponding to a specific wavelength (around 1550nm). The use of an LC duplex connector ensures a secure and reliable connection to the fiber optic infrastructure. Its SFP+ form factor ensures compatibility with a wide range of Arista switches and other network devices that support this standard. The Arista SFP-10G-DW-42.94 is engineered for reliability and performance in mission-critical environments. It is ideal for service providers, large enterprises, and cloud providers who require high-bandwidth, long-distance connectivity. By enabling efficient use of existing fiber infrastructure through DWDM technology, this transceiver helps reduce costs and increase network capacity.
