The single-mode 1310/1550 Wavelength Division Multiplexers can couple the optical signals (1310nm or 1550nm) transmitted in optical fiber. In other words, it has two functions: add an optical signal onto another one, then combine the two optical signals into one fiber (Combination); drop one optical signal from the mixed optical signals (Division).It is the primary unit for high-performance WDMs. Adequate experiments and customers’ feedbacks have showed that our Yuwei all-optical WDM units, which were produced by FBT technique, have good performance in applications.
