Introduction
Analysis of the core content of the standard
This standard specifies the technical requirements for GSM-R digital fiber repeater in the railway communication system, including:
- System architecture: networking mode of near-end machine-fiber-remote machine
- Key functions: 8 core functions such as relay transmission, noise suppression, and delay adjustment
- Performance indicators: three major categories of technical parameters: RF, fiber, and network
Detailed explanation of RF performance indicators
| Indicator items | Technical requirements | Test conditions |
|---|---|---|
| Operating frequency band | Uplink 885-889MHz Downlink 930-934MHz | Full temperature range |
| Output power | 37-43dBm(single port) | ALC start point±2dB |
| Vector amplitude error | ≤6% RMS | 8PSK modulation |
Fiber optic transmission characteristics
Need to meet the following requirements in typical networking scenarios:
- Optical path dynamic range ≥15dB
- Optical bypass switching time <800ms
- Support star/ring hybrid networking
Engineering suggestions: When configuring a ring network, the optical ring protection function must be configured to ensure that a single point failure does not affect the overall communication
Standard evolution analysis
Main improvements compared to the previous generation of standards:
- Added 8PSK modulation support
- Enhanced delay compensation accuracy (±2μs)
- Clearly define interleaving redundant coverage requirements
