The Q SFP 40G 20KM OPTI-CODE is a high-performance optical transceiver module designed to support data transmission rates of up to 40 Gbps over distances of up to 20 kilometers. It utilizes a small form-factor pluggable (SFP) interface, which is widely used for high-speed networking equipment, such as routers and switches. The module is typically based on advanced fiber optic technology, offering low-latency and high-bandwidth capabilities, making it ideal for data centers, enterprise networks, and telecommunications infrastructure. The 20KM transmission distance is supported by single-mode fiber (SMF), providing long-range connectivity while ensuring stability and efficiency for high-volume data traffic. The OPTI-CODE ensures compatibility with a wide range of networking devices, making this module a versatile and reliable choice for upgrading or expanding network infrastructures with robust 40G connectivity.
