NeoPhotonics Corporation, a leading designer and manufacturer of hybrid photonic integrated circuit based modules and subsystems for bandwidth-intensive, high speed communications networks, today announced here at the Optical Fiber Communications conference and exhibition its low power consumption 56GBaud EML lasers and drivers for both 4x100G PAM4 and 8x50G NRZ client side 400G transceivers.
With the ever-growing demand for more bandwidth, datacenter operators and service providers are actively looking into the client side interface technologies beyond 100G, with 400G the clear next standard. NeoPhotonics’ latest 56GBaud products enable 400G interfaces with two possible solutions. First, with a PAM4 modulation scheme, the combination of a 56GBaud EML with a linear 56GBaud driver can achieve a 100Gbps data rate with one single laser. A 400G interface will use four wavelengths with PAM4 modulation. Second, a traditional NRZ modulation scheme with NeoPhotonics’ 56G EML and limiting driver can deliver 400G of capacity with eight wavelengths.
“The development of high speed components such as our 56Gbaud EML lasers and drivers by NeoPhotonics Semiconductor is the result of our commitment to lead in the technologies required for the ultra-high speed segment of the transceiver market,” said Tim Jenks, Chairman and CEO of NeoPhotonics. “We are pleased to support our customers and the industry with a solid and growing portfolio of high performance components based on our proven Indium Phosphide EML and Gallium Arsenide pHEMT technologies and to facilitate the next-generation 400G market with low power consumption and cost-effective components,” continued Mr. Jenks.
