How to choose the appropriate optical switch channel count based on the application scenario?
As a key component in optical communication networks, the channel count of an optical switch directly impacts system performance, cost, and scalability. The channel count requirements for optical switches vary significantly across different application scenarios. Choosing the right channel count can ensure both functional requirements and resource waste. This article will systematically explain how to choose the appropriate optical switch channel count by categorizing application scenarios, selecting criteria, and using typical examples.
I. Overview of Optical Switch Channel Count
The channel count of an optical switch refers to the number of optical signal paths that the switch can simultaneously switch, typically expressed as N×M (N input ports, M output ports). Common configurations include:
| Channel number type | Typical representative | Advantages | Applicable scenarios |
| Low channels | 1X2 ,2X2 | Very low loss (0.4-0.8) and fast switching (≤8ms) | Network protection switching, simple routing |
| Middle Channels | 1X4,1X8,1X16, 4X4,8X8,16×16 | High stability, excellent repeatability (±0.02dB) | Fiber optic testing, multipath management |
| High Channels | 1X32,1X48, 1X64,1X128 | Supports parallel processing to meet high throughput (<2.5dB loss) | Data center and AI cluster interconnection |
| Ultra High Channels | 1X256,32X32, 64X64 | Build complex optical matrices to achieve wavelength-level scheduling | Core OXC nodes, backbone network |
