AI Overview
Z-Block transceivers are compact optical subassemblies used in high-speed (100G–800G) data center transceivers for wavelength division multiplexing/demultiplexing (WDM). They integrate filters, prisms, and lenses to efficiently multiplex/demultiplex signals, providing low insertion loss and high isolation in a compact footprint.
Key details regarding Z-block technology include:
- Technology Application: Used in high-speed data center network optics, including SWDM, CWDM, and LAN-WDM formats.
- Key Components: The Z-block typically includes a receptacle, collimator, lens array, and prism to manage light routing.
- Functions: These modules handle optical signals at the receiver (RX) end, facilitating the alignment of optical components.
- Performance Benefits: They offer high temperature stability and facilitate rapid alignment due to their monolithic design.
- Providers: Major suppliers include Coherent, HYC Co., Ltd., Gigalight, and Hitronics Technologies Inc..
