  • Optical to Electrical Interface Module

    Optical to Electrical Interface Module

    An electrical port module, also known as an optical-to-electrical port converter module, is a hot-swappable device with an SFP form factor. It features an RJ45 connector and uses UTP cables as the transmission medium. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside. The Keysight N7005A Optical-to-Electrical Converter is a high-sensitivity photodetector module designed for direct optical-to-electrical conversion of optical signals into Infiniium UXR realtime oscilloscope with AutoProbe III interface (≥40 GHz). The electrical signal is converted into an optical signal through the transmitting end of the optical module, and then converted into an electrical signal through the receiving end. The Lumentum tunable SFP+ module is a high performance tunable pluggable transceiver for use in the C-band window covering 1528 nm to 1566 nm. The module supports data rates from 9. 3 Gbps and is provided in an SFP+, MSA-compliant package. For measurements in laboratories and manufacturing, optical signals often need to be converted to electrical pulses.
