Description
The ONS-QSFP-40G-SR4 is a networking product manufactured by Cisco. It is a high-speed optical transceiver designed for use in data centers and other networking environments. It is capable of transmitting and receiving data at speeds up to 40 gigabits per second.The device is compact and efficient, making it ideal for use in high-density network environments. It features four independent channels, each capable of transmitting data up to 10 gigabits per second. This allows for greater flexibility in network design and reduces the need for multiple transceivers.The ONS-QSFP-40G-SR4 is a multimode optical transceiver, meaning it uses multiple fibers to transmit and receive data. It uses a standard MPO connector, which makes it easy to incorporate into existing network infrastructure.Overall, the ONS-QSFP-40G-SR4 is a reliable and high-performance networking solution that is well-suited for data centers and other high-bandwidth environments. Its small size, high speed, and compatibility with existing infrastructure make it an attractive option for network administrators looking to upgrade or expand their networks.- Part Code

dot3StatsLCVErrors/mediaIndStatsRxLcvErrors
Received line code violations at the PCS layer
dot3StatsLayer1Errors
Number of Layer 1 errors as defined within the following conditions:
During Packet Reception - Layer 1 errors are counted only one time per packet. The error is indicated as a direct result of a line side protocol violation in which RX_DV is asserted. This is an uncommon event that could the reason why a device loses synchronization.
During Interpacket Reception - The Layer 1 error is indicated as a direct result of a line side protocol violation in which RX_DV is deasserted. This is an uncommon event. The Layer 1 error is also asserted on detection of a False Carrier indication and an errored byte (interpacket) signal encoding. When the error is asserted during interpacket reception, it is statistically asserted only in the vector.
