A low-power-consumption, 28-GBaud externally modulated laser (EML) with an integrated driver from Neophotonics Corp. is designed for client side 4 x 25 NRZ 100-G, 4 x 50 PAM4 200-G and 8 x 50 PAM4 400-G applications.
The EML integrates a driver, which utilizes low-power linear GaAs amplifier technology, with the 28-GBaud EML at the chip-on-carrier (CoC) level. The CoC assembly fits into a four-channel transmitter optical sub-assembly (Quad TOSA), designed for 100-Gbps QSFP28 and CFP4 form factors, eliminating the need for a separate driver on the board.
Customers can directly link the CMOS-based CDR IC to the 28-GBaud CMOS drivable EML for low-power consumption and space savings. In PAM4 applications, the integrated linear driver the EML an attractive option for 200- and 400-Gbps applications due to the simple and direct connection to the PAM4/CDR IC.
