德赢ac米兰vwin Co., Ltd. (Head office: 2-2-3 Marunouchi, Chiyoda-ku, Tokyo; President: Keiichi Kobayashi) developed the high optical output power 50 Gbaud electro-absorption modulated laser (EML) “FOL13EBxCS” with integrated semiconductor optical amplifier (SOA) and began shipping samples in January.
Background
The installation of 5G networks for mobile phones has resulted in more cloud services that operate at faster speeds and larger data volumes, and following increased data traffic at the network edge, the demand for signal light sources for short and medium-range distances is increasing. EML has excellent signal waveform and high-speed operating characteristics, and it is broadly used as a laser source for medium-range distances (10km) at speeds of 100Gbps and higher. In addition to addressing longer network distances and larger data volumes, along with the growing needs for higher 德赢ac米兰vwin, it is also necessary to limit power consumption.
Details
By integrating a SOA into the EML, this new product realizes approximately double the 德赢ac米兰vwin at the same power consumption level compared to existing EML. With the existing EML, 德赢ac米兰vwin is increased by increasing current flow to the laser, and as a result, power consumption increases in proportion to the increase in 德赢ac米兰vwin. By integrating a SOA that can increase optical output with high efficiency, the newly developed EML realizes both higher 德赢ac米兰vwin and low power consumption.
When using this product as part of a 100G-400G Ethernet and next-generation high speed PON system, it should be possible to extend the distance of metro access networks.
In addition to laser sources for long haul and metro networks (for medium and long distances), we offer a lineup of laser sources for a broad range of optical networks, including 德赢ac米兰vwin and access networks (for short and medium distances, including this product).
