T800 High Performance Clock Server
Product Description
Designed for high-frequency trading and other low-latency network applications, the T800 high-performance clock server is the perfect combination of highly optimized timing protocols and clock management capabilities. The combination of full GNSS concurrent reception, sophisticated clock taming algorithms, and local clocking provides the flexibility and performance needed to meet the demands of evolving network architectures. The Clock Server provides multiple 1GbE (RJ-45) and 10GbE (SFP+) network ports, integrates a high-precision IEEE 1588-2008 PTP packet gateway clock and Silicon Lab Si5348 ultra-low jitter network synchronizer, which is compatible with SyncE standard phase and frequency synchronization, and combines jitter attenuation and clock regeneration, and supports both NTP and SNTP network synchronization protocols.
The hardware of the device adopts redundant architecture design, and the high-precision clock is directly derived from the atomic clocks of each satellite in the GNSS system, and the local clock source is tamed through signal analysis to realize the function of keeping the local clock accurately after the loss of satellite signals. The software of the device adopts a variety of anti-jamming detection and identification algorithms of Beidou Bontec to detect the signal abnormality caused by interference and malicious attacks on GPS signals. Unique embedded hardware design, high-efficiency Linux operating system, can flexibly expand a variety of clock signal output. Meanwhile, it supports TOD, 10MHz, 1PPS, logging, USB port upgrade and download, and dry contact alarm function, which can easily realize network time synchronization and effective monitoring with Beidou Bontec's self-developed network time unified monitoring software.
T800 high-performance clock server can be widely used in government, national defense, finance, securities, insurance, mobile communications, cloud computing, e-commerce, energy and power, petroleum and petrochemical, industrial automation, intelligent transportation, security, smart city, Internet of Things and other fields.
