100G QSFP28 Transceiver


QSFP28 Optical Transceiver

The 10Gtek 100G QSFP28 transceiver is a 100Gb/s Small Form-factor Pluggable (QSFP28) optical module. The QSFP28 full-duplex optical module offers 4 independent transmit and receive channels, each capable of 25Gb/s operation for an aggregate data rate of 100Gb/s.

10Gtek's 100G QSFP28 Transceivers family includes solution from 100m to 10km transmission ranges, from MMF to SMF and use MTP/MPO or LC-LC connector, which designed to maximize their port density and minimize operating costs, providing a variety of options for data center interconnect solution, telecom networks. Digital diagnostics functions are available via an I2C interface, as specified by the QSFP28 MSA. The transceiver is RoHS-6 compliant.

10Gtek's new released 100G QSFP28 Transceivers (QSFP28 SR4, QSFP28 LR4, QSFP28 IR4PSM, QSFP28 CWDM4) will help to drive next generation of data center and enterprise interconnects.
