HANSUN OPTICS 100G QSFP28 ER4 Lite optical Transceiver integrates receiver and transmitter path on
one module. In the transmit side, four lanes of serial data streams are recovered, retimed, and passed to four
laser drivers. The laser drivers control 4- EML with center wavelength of 1296 nm, 1300nm, 1305nm and
1309 nm. The optical signals are multiplexed to a single –mode fiber through an industry standard LC
connector. In the receive side, the four lanes of optical data streams are optically de-multiplexed by the
integrated optical de- multiplexer. Each data stream is recovered by a APD and trans-impedance amplifier,
retimed. This module features a hot-pluggable electrical interface, low power consumption and MDIO
management interface.
The product is designed with form factor, optical/electrical connection and digital diagnostic interface
according to the QSFP28 Multi-Source Agreement (MSA) and compliant to IEEE 802.3bm.

Notes:

  1. GND is the symbol for signal and supply (power) common for QSFP28 modules. All are common within the QSFP28 module and all module voltages are referenced to this potential unless otherwise noted. Connect these directly to the host board signal common ground
  2. VccRx, Vcc1 and VccTx are the receiving and transmission power suppliers and shall beapplied

concurrently. Recommended host board power supply filtering is shown below. Vcc Rx, Vcc1 and Vcc Tx may be internally connected within the QSFP28 transceiver module in any combination. The connector pins are each rated for a maximum current of 500mA.
