Simple to use. To route signals, just turn a knob on the front panel. Ideal for government, healthcare, financial, or other applications where a private, data-sensitive network connects to a publicly accessible network. For reliable switching in mission-critical environments, the micro-mirrors are bonded to precise positioning servos. Enables you to connect a single workstation to two or more networks or remote devices. Latching switches latch mirror movement mechanically into a selected position and hold it there without the need for continuous electrical power. All non-latching versions except for the SW1003A fall back to C-to-A position if power is lost (the SW1003A falls back to the OFF position). The OFF position on the SW1003A also prevents host-to-remote device communications. Models with loopback enable you to test an idle fiber link from a central office to ensure that the circuit is operating correctly. Operate transparently to signal rates, formats, and wavelengths, and don't require an upgrade when your data protocols change or speeds increase. Work with 62.5-/125-micron multimode. Universal 100-240-VAC power supply. There's a reason why this type of manual switch continues to be the switch of choice for networking professionals everywhere: The tried-and-true optical switches perform as promised year after year. It's reliable because it uses micro-mirrors instead of electronics to route data signals from one fiber optic port to the next. And unlike conventional electronic switches, it is not complex and vulnerable electronic circuits to monitor and protect from intrusion, component failure, or interference. The switch is available in latching and non-latching models. The optical mirror movement on the latching versions maintain the selected position even when there's a power failure. You can also order an A/B switch with unique loopback capabilities. Using loopbacks, you can verify the integrity of your backup fiber link while still connected to your primary fiber link. This is especially useful in failover applications where you want to continuously test the "unused" circuit to ensure that it's available if needed.
