N Bit Lossless Variable Photonic Time Delay Module
This N-bit (N ≥ 10) Photonic Time Delay Module selectively routes optical signals through N fibre segments with the different lengths. Each fibre segment is defined to have the delay as
ΔT
i
= 2
(i-1)
ẟT , i = 1,2,...N
Where ẟT is the increment of time delay.
Therefore, the module provides N-bit of digitally variable time delay, having the total time delay as
ΔT
Total
= (2
N
- 1) ẟT
N and ẟT can be defined by customer.
The EDFAs is used in the module to compensate the optical loss through optic fibre segments and switches. The optical loss between the optic fibre segment and the bypassing path is balanced internally to get the excellent uniformity of optical power between different time delays in long time delay ranges.
