How Are Optical Delay Lines Used in Telecommunications?
Optical delay lines play a crucial role in various telecommunications applications: · Optical Time-Division Multiplexing (OTDM): Delay lines are used to synchronize multiple optical signals that are multiplexed in the time domain. By introducing appropriate delays, the signals can be aligned at the receiver to prevent interference. · Optical...

Optical Delay Lines in Quantum Key Distribution (QKD): Synchronization Challenges
Quantum Key Distribution (QKD) enables ultra-secure communication by leveraging the principles of quantum mechanics to exchange cryptographic keys. A critical component in many QKD systems is the optical delay line (ODL), which introduces precise time delays to synchronize photons or compensate for path-length differences. However, implementing ODLs in QKD presents several synchronization...

What Are the Different Types of Optical Delay Lines?
There are several types of optical delay lines, each with its own unique characteristics and applications: l Fixed Fiber Delay Lines: These use a fixed length of optical fiber to introduce a specific delay. They are simple and reliable but lack flexibility. l Variable Fiber Delay Lines: These allow for adjustable delays by using mechanisms to vary the length of the...
