Product Description
The Arista SFP-10G-DW-37.40 is a high-performance 10 Gigabit Ethernet SFP+ optical transceiver module designed for demanding long-haul network applications. It is specifically engineered for operation within Dense Wavelength Division Multiplexing (DWDM) systems, enabling efficient use of fiber optic infrastructure by allowing multiple data channels to coexist on a single fiber. This transceiver supports data rates of 10Gb/s and is capable of transmitting signals over distances of up to 40 kilometers using single-mode fiber (SMF). The 'DW' designation signifies its compatibility with DWDM technology, and the '37.40' likely refers to a specific ITU grid channel, ensuring interoperability within a DWDM system. The use of SMF is crucial for maintaining signal quality over these extended distances. Featuring a standard Duplex LC connector, the SFP-10G-DW-37.40 provides straightforward integration with Arista and other compatible networking equipment that supports the SFP+ form factor. Its hot-pluggable design allows for seamless installation and replacement without interrupting network traffic, simplifying network management and upgrades. This transceiver offers a reliable and scalable solution for extending network reach and increasing bandwidth in modern optical networks.
