Guanglian's 100G QSFP28 LR4 transceiver modules are designed for use in 100BASE Ethernet throughout up to 10km over single mode fiber（SMF）with duplex LC connectors.

Guanglian’s QSFP28/CFP2 LR4-Rx optical transceiver integrates receive path into one module. The receiver four lanes of optical data streams are optically de-multiplexed by an integrated optical de-multiplexer.

Guanglian’s 100G QSFP28-ZR4 Optical Transceiver Module is designed for use in 100GBASE Ethernet and 4x28G OTN client interfaces throughput up to 80km over single mode fiber (SMF) with duplex LC connectors.

Guanglian's 100G QSFP28 PSM4 Optical Transceiver Module is designed for use in 100GBASE Ethernet throughput up to 500m/2km over single mode fiber (SMF) using a wavelength of 1310nm via a MTP/MPO-12 connector.

Guanglian's 100G QSFP28 PSM4 Optical Transceiver Module is designed for use in 100GBASE Ethernet throughput up to 500m/2km over single mode fiber (SMF) using a wavelength of 1310nm via a MTP/MPO-12 connector.

Guanglian’s 200GBASE-SR4 optical transceiver module supports link lengths of up to 100m over multimode fiber (MMF) with MTP/MPO-16 connector.
