Optcore SFP-2.5G-T

The SFP-2.5G-T transceiver is a versatile component that enhances network performance by facilitating high-speed Ethernet communication. It is compatible with a wide range of network devices, including switches, routers, and servers, making it a valuable addition to any network infrastructure. Its design is optimized for 2.5GBase-T Ethernet over Cat5e/Cat6a cables, ensuring efficient data transmission. The use of the RX_LOS pin for link indication and the TX_DISABLE pin for PHY IC reset are critical features that contribute to its functionality. Moreover, the transceiver’s ability to buffer packets in both ingress and egress directions ensures smooth data flow, while the option to enable flow control on the host side MAC provides an additional layer of traffic management to accommodate varying network speeds.
