At the 20th China International Optoelectronic Exposition (CIOE 2018) in Shenzhen, China (5-8 September), Tokyo-based Mitsubishi Electric Corp has launched the ML760B54, a 25Gbps electroabsorption modulated laser (EML) CAN module (to be commercially available from 1 November), supporting high-speed optical data transmission in radio access networks within fifth-generation (5G) mobile base stations.
The introduction of 5G mobile networks will herald the transmission of huge volumes of data and the need for high-speed optical communication networks, notes Mitsubishi Electric. This will in turn drive customer demand for high-speed optical devices with low power consumption. The firm says that its new 25Gbps EML CAN module addresses these requirements, and can help to improve the productivity and efficiency of customer installations.
Mitsubishi Electric says that the new module supports high-speed, large-volume mobile networks by leveraging the improved bandwidth of a TO-CAN package (claimed to be a first for a 25Gbps EML). The emission wavelengths are 1270±10nm of 1310±10nm.
The module also reduces power consumption within mobile networks (by cutting the power consumption of the thermo-electric cooler by 40% compared with the existing FU-411REA model, to 0.28W typically at + 95°C). The operating case temperature range is –40°C to + 95°C. Optical output power is typically more than +10dBm. The extinction ratio is typically more than 6dB.
Finally, the ML760B54 is expected to improve the productivity and efficiency of customer installations. Specifically, being compatible with the standard 5.6mm TO-56 CAN package, a simplified fabrication process should improve the productivity of bi-directional optical modules and transceivers.
