Greek Active Optical Device 200G

The Greek 200G Active Optical Device is a high-speed 200G Active Optical Cable (AOC) or transceiver module designed for data center and telecommunication applications, supporting short-distance multi-channel 200G Ethernet transmission.OverviewA 200G Active Optical Device, commonly implemented as a 200G AOC or QSFP56/QSFP-DD transceiver, is an active fiber optic module that integrates both electro-optical and opto-electronic conversion chips to transmit high-speed signals over optical fibers . These devices are widely used in data centers, enterprise networks, campus networks, metropolitan networks, and 5G wireless backhaul .Types and SpecificationsQSFP56 AOC: Features four transmit and four receive channels, each capable of 56Gbps using PAM4 modulation, suitable for 200G Ethernet over distances of 1–100 meters .QSFP-DD AOC: Features eight transmit and eight receive channels, each capable of 28Gbps using NRZ modulation, also supporting 200G Ethernet .Transmission Distance: Using OM3 fiber, up to 70 meters; using OM4 fiber, up to 100 meters .Power Consumption: Typically less than 4W for 200G modules, with lower power for breakout configurations (e.g., 2x100G or 4x50G), .Wavelength: Nominally 850nm for multi-mode fiber systems .Working PrincipleThe device converts electrical signals into optical signals at one end using an electro-optical conversion chip. The optical signal is then transmitted through the fiber, modulated, and coupled efficiently. At the receiving end, an opto-electronic conversion chip converts the optical signal back into an electrical signal for network equipment . This allows high-bandwidth, low-latency, and low-power interconnects in dense data center environments .ApplicationsData Center Interconnects: High-speed links between servers, switches, and storage devices.Branching Ethernet Links: 200G AOCs can be split into 2x100G or 4x50G links for flexible network deployment .Telecommunication Networks: Used in metropolitan, campus, and 5G fronthaul networks .High-Performance Computing: Supports InfiniBand and Ethernet 200GBASE CR4 applications .AdvantagesHigh Bandwidth: Supports 200G Ethernet with multiple channels.Low Latency and Power Consumption: Optimized for data center efficiency .Flexible Deployment: Breakout options allow conversion to lower-speed links.Compact and Pluggable: QSFP56 and QSFP-DD form factors enable dense port configurations.Related ComponentsSome 200G devices may include photodiodes with integrated lenses for efficient optical coupling, such as the PD50Y1, which supports 200G PAM4 applications and wavelengths from 1260–1620nm . These components enhance signal quality and enable high-speed optical communication. In summary, the Greek 200G Active Optical Device is a high-performance, multi-channel optical module designed for short-distance, high-speed Ethernet and data center interconnects, offering flexibility, low power consumption, and reliable optical transmission for modern network infrastructures .
