The Arista OSFP-400G-FR4 is a single form factor pluggable (SFP) optical module designed to meet the increased demand for efficient and high-capacity data transmission over long distances. It supports the 400GbE Ethernet standard and offers a maximum link distance of up to 10 kilometers in a single mode fiber (SMF) configuration. The SFP module can also be configured for an intermediate 120km reach over SMF with FEC (forward error correction). The Optical SFP module offers double the port density of traditional transceivers, upcoming 400GbE switches will benefit from its superior performance with up to 64 ports leveraging four lanes of OSFP-400G-FR4. Its form factor design allows users to operate the transceiver in multiple data centers using existing Low profile QSFP+ cages and breakout cables. The transceivers are also energy efficient operating at lower power consumption than the competition, rated at 12W per port. The optical transceiver utilizes advanced technological features such as Forward Error Correction (FEC) to further increase performance even in challenging environments. In addition, its advanced DSP technology ensures optimal performance and interoperability with other vendor's Type B optics. Lastly, it comes with integrated digital diagnostics monitoring (DDM) capabilities, which enable IT professionals to monitor transceiver parameters such as temperature, voltage, and signal quality from a remote location. The comprehensive list of hardware specifications found in the Arista OSFP-400G-FR4 makes it one of the industry's highest performing optical transceivers available today. Its superior features and superior performance make it the perfect choice for 400GbE applications in a wide range of environments. With its cutting edge technologies, impressive form factor, and competitive price point, this is an ideal option for those looking for reliable data transmission over long distances.
