T900-F Fiber Optic High Precision Frequency Transmission Equipment

The T900-F is a high-precision fiber-optic frequency transmission device based on a ring network structure. A central station transmits frequency signals through a closed loop and uniformly compensates for phase fluctuations, eliminating the need for individual phase stabilization at each node. This system offers high scalability and low maintenance. The reproduced frequency signal stability reaches 3×10⁻¹⁴@1s and 1×10⁻¹⁶@10,000s, making it suitable for high-precision frequency synchronization applications in basic scientific research, deep space exploration, and high-end equipment.

T900-P Fiber Optic High Precision Time Transfer

The T900-P is a high-precision fiber-optic time transfer device based on wavelength division multiplexing links. It utilizes a central station and terminal station architecture and incorporates bidirectional time comparison technology to achieve stable, interference-resistant time and frequency synchronization within DWDM channels. The system supports a transmission distance of 100 kilometers and offers synchronization accuracy better than 40ps. It is widely used in high-precision synchronization scenarios such as deep space exploration, national defense, and scientific research.

T910 WR Clock Synchronization Switch

The White Rabbit Switch (WRS) is a core device for high-precision time synchronization and frequency distribution, supporting 18 fiber-optic synchronization ports and clock synchronization accuracy better than 10 ps. Combining a hardware platform with an embedded Linux system, it supports multiple management interfaces such as SNMP, SSH, and the Web, and is compatible with PTPv2, Sync-E, and VLAN protocols. It features master/slave mode, automatic fiber delay compensation, and supports cascaded deployment of 10,000 nodes. It is widely used in scenarios such as dual-base radar, adaptive antenna arrays, and distributed time measurement.

T920 High-Precision Satellite Common View Receiver

The T920 is a high-precision common-view satellite receiver that supports GPS, GLONASS, BeiDou, and Galileo systems, complying with CCTF (2015) and CGGTTS V2E standards. It features OSNMA signal authentication, AIM+ interference mitigation, APME+ multipath estimation, and supports multiple data formats such as RINEX and BINEX, along with 16GB of local storage. It outputs 1PPS, 10MHz, NTP, and PTP signals, and supports synchronization accuracy assessment and remote web management. It is ideal for international time comparisons, metrology laboratories, research institutions, and augmented navigation applications.
