MACOM’s MAOP-L284CN features four high bandwidth Mach-Zehnder modulators integrated with four lasers (1270, 1290, 1310, and 1330 nm) and a CWDM multiplexer, with each channel operating at up to 28 Gbps. The L-PIC transmitter operates on a standard single mode optical fiber, and includes integrated tap detectors for fiber alignment, system initialization and closed loop control. A single fiber aligned to the output edge coupler of this 4.0 x 6.6 mm die is the only optical connection required for integrating this device into QSFP28 transceiver applications. A bidirectional coupler is provided on the multiplexed output to facilitate both fiber coupling and to monitor output power via an integrated photodiode. The MAOP-L284CN is available as part of a complete MACOM chipset platform, including the MAMF-011095 silicon PIC controller and the MASC-37053A high-speed, low-power modulator driver. Optimized to work together, this chipset solution offers customers improved performance, eliminates the need for assembly of discrete components, reduces configuration and test costs, and accelerates time to market.
