동기식 광통신망 (SONET, Synchronous Optical Network)

🇬🇧 Component focus: TRU-600A – clock recovery module ⏱️✨ Introducing a little gem of engineering for optical networks: the TRU-600A. This electronic module is designed to extract a stable clock from a digital data stream (NRZ), typically in SONET/SDH systems (synchronous optical networks). 💡 📡 It operates at data rates of up to 622 Mb/s (OC-12 / STM-4) and offers ultra-low jitter thanks to its surface acoustic wave (SAW on quartz) filter technology. In other words, it cleans the signal and t
