power spectrum when A = υ 2 and B = υ 2
When A is at frequency υ 2 (1560 nm), input B is at frequency υ 1 (1550 nm) ,
output is at frequency υ 1 as 1550 nm.
When A is at frequency υ 2 (1560 nm), input B is at frequency υ 2 (1560 nm) ,
output is at frequency υ 2 as 1560 nm.
The optical spectrum of BORROW bit is shown in Fig. 8a–d. When A is at
frequency υ 1 (1550 nm), input B is at υ 1 (1550 nm), output is at frequency υ 1
(1550 nm).
