Accelight’s 100Gbps QSFP28 ZR4 transceiver module is designed for use in 100 Gigabit Ethernet links
over 80km single mode fiber. The module has 4 independent electrical input/output channels operating
up to 25.78Gbps per channel. This transceiver consists of transmitter/receiver units, with each operating
on a set of 4 wavelengths on the ITU G.694.1 LAN-WDM grid near 1310nm. The transmitter path of the
module incorporates 4-channel EMLs and 4-channel modulator driver. On the receiver path, a 1-channel
SOA, 4-channel PD array, and 4-channel TIA array are used, along with NRZ retimers.
