Description
Springtek 100G PSM4 QSFP28 single mode optical transceiver designed for optical communication applications. This product provides increased port density, offering four independent transmit and receive channels,Each channel operates at 25Gbps, resulting in an aggregate data rate of 100Gbps on 2km of single mode fiber,An optical fiber ribbon cable with an MTP/MPO connector can be plugged into the QSFP28 module receptacle,The guide pins inside the receptacle ensure proper alignment.
according to the QSFP28 Multi-Source Agreement (MSA),The module can be managed through the I2C two-wire serial interface. The transmitter module accepts electrical input signals compatible with Common Mode Logic (CML) levels,All input data signals are differential and internally terminated. The receiver module converts parallel optical input signals via a photo detector array into parallel electrical output signals. The receiver module outputs electrical signals are also voltage compatible with Common Mode Logic (CML) levels. All data signals are differential and support a data rates up to 25Gb/s per channel.
