MACOM launches 25G APD photodiode and 25G Fabry-Perot laser for next-gen 5G and data-center networks

MACOM Technology Solutions Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for analog RF, microwave, millimeter-wave and photonic applications) has announced the availability of its 25G avalanche photodiode (APD) and 25G Fabry-Perot (FP) laser optical components for 5G wireless and data-center applications.

The APD28A is a back-illuminated 25G APD covering both O- and C-bands with a usable wavelength range of 1250-1650nm. The photodiode features greater than 20GHz (3dB) bandwidth, with very high sensitivity of -22dBm when coupled to a low-noise amplifier (LNA) for 25G NRZ and 50G PAM-4 transmission applications.

The device performance enables the design of optical sub-assemblies and transceivers suitable for 5G wireless mid-haul and long-haul networks, and extended-reach (ER4) applications for 100Gbps, 200Gbps and 400Gbps data-center applications.

MACOM will offer the 25G APD as a bare die and in chip-on-carrier format to provide maximum design flexibility to customers.

The MAOD-131F25 is a directly modulated high-speed 25Gbps 1310nm Fabry-Perot laser diode with a wide operating temperature range of -40oC to +95oC. The device leverages MACOM’s patented and proven etched facet technology (EFT) enabling scalability to high-volume manufacturing. The 25G FP laser is suited to enabling 5G LTE front-haul short-reach applications as well as low-cost 100Gpbs parallel single-mode fiber (PSM4) application for data centers.

MACOM will offer the 25G Fabry-Perot laser in a TO-Can package to complement customer requirements and accelerate time to market.
