The 1.25G SFP Tx1490/Rx1550 transceiver is designed for high-performance, long-range data transmission at 1.25Gbps over single-mode fiber (SMF), with a reach of up to 80 kilometers. It features a 1490nm transmitter for sending signals and a 1550nm receiver for receiving data, ensuring stable and reliable transmission even over long distances. Ideal for telecommunications, metropolitan area networks (MANs), and other long-haul optical applications, this module provides an efficient solution for large-scale networks requiring extended reach. The compact SFP form factor with LC connector enables high-density integration, while its low power consumption makes it a cost-effective choice for long-distance, high-speed communications.
