STM-1~ STM-16 and low-speed Ethernet SFPs are supporting optical fiber transmission from 2km to 80km. Longer transmission distances can be realized based on specific customer requirements. SFPs support hot pluggablity and have the characteristics of low power consumption, small size and wide application scenarios. Taclink OSC optical Transceiver modules support 1491nm / 1511nm / 1625nm / 1645nm and other wavelengths up to 240 km non-amplified transmission distances. In addition also a single fiber bi-directional (BIDI) version 1491nm / 1511nm is available.
