1 × N? Mechanical single-mode optical switch module is mainly used in fiber optic transmission systems and fiber optic test systems, optical transmission systems including multi-channel optical monitoring,? LAN ?, multi-source? /? Detector for access and Ethernet protection conversion; fiber optic test systems including optical fiber and optical fiber device testing, network testing, field testing fiber optic cable, fiber optic sensor multi-point monitoring. The role of the product is to switch the optical path, with good stability, high reliability, low loss, multi-output, modular design and parallel interface (? TTL) and so on. Features: up to 128 low-loss, high reliability modular design parallel interface (TTL level) Parameters Parameter Value Operating wavelength (nm) 532-980 (MM) 532-980 (SM) 1260-1620 (MM ) 1260-1620 (SM) test wavelength (optional) (nm) 650/780/850/980 650/780/850/980 1310/1490/1550/1625 1310/1490/1550/1625 Insertion Loss (dB) Typ : 0.6 Max: 1.0 Typ: 0.6 Max: 1.0 Typ: 0.6 Max: 0.9 Typ: 0.6 Max: 0.9 insertion return loss (dB) SM≥50, MM≥30 channel crosstalk (dB) SM≥55, MM≥35 polarization dependent loss (dB) ≤0.05 wavelength dependent loss (dB) ≤0.25 temperature dependent loss (dB) ≤0.25 Repeatability (dB) ≤ +/- 0.02 life (times) 10 ^ 10 times the transmission optical power (mW) ≤500 Switching time (ms) ≤8 (adjacent channel switching) Operating Temperature (℃) -20 ~ + 70 Storage Temperature (℃) -40 ~ + 85 power supply (V) 5 or12 module Dimensions (mm) 1≤N≤12 (135 × 64 × 32) 8≤N≤16 (184 × 78 × 38) 16≤N≤48 (184 × 78 × 66) 48≤N≤96 (206 × 78 × 66)
