Request InfoLumentumA 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.
