- High-Temperature Stability and Reliability: The high-temperature stability ensures consistent performance across a wide range of operating conditions, enhancing the reliability of the system.
The series is available in various models, each tailored to specific applications and requirements. For instance, the SGTF40-1550-1TP-2A and SGTF40-1550-1TP-2D models offer a shift frequency of 40 MHz, while the SGTF200-1550-1TP(H)-2A and SGTF200-1550-1TP(H)-2D models provide a higher shift frequency of 200 MHz. These models support both digital and analog modulation modes, with digital modulation operating at high levels of 3.3-5V and low levels of 0-0.2V@1kΩ, and analog modulation supporting a range of 0-1V@50Ω.
The complete machine specifications include a wavelength range of 1530-1570 nm, fiber types such as PM1550 (polarization maintaining) and SMF28e (single-mode), and an on-off extinction ratio of ≥50 dB. The polarization extinction ratio for PM devices is ≥20 dB, while the polarization-dependent loss for SM devices is <0.5 dB. The optical power is limited to ≤0.5 W, and the fiber length is ≥1 m, with FC/APC connectors for optical fiber connections.
