26-pin parallel interface. It connects a single fiberoptic channel to any of N (up to 26) channels. Small and rugged, the SK Series switch module is designed to be used in embedded applications and is available in both single-mode and multimode versions. -
Page 10: Key Features
The SK switch operates on a single 5 V ±5% DC power supply and is controlled through a simple parallel interface consisting of seven data lines, a reset line, a strobe line, and a busy line. Key Features • Up to 26 channels •... -

Page 13: Getting Started
Getting Started The SK Series Fiberoptic Switch Module consists of the switch and a ribbon cable with a standard dual row connector. Before Initializing and Operating the Unit Inspect the unit for any signs of damage. Read the user’s manual thoroughly, and become familiar with all safety symbols and instructions to ensure that the unit is operated and maintained safely. -
Page 14: Humidity
Humidity The unit can be operated in environments with up to 95% humidity (non-condensing, 0 to 55 °C). Do not expose it to any environmental conditions or changes to environmental conditions that can cause condensation to form inside the unit. Warning •... -

2. Apply optical grade isopropyl alcohol or optical grade ethanol (do not use rubbing alcohol) to a small area of a lint-free towel and rub the end of the ferrule over the wet area. 3. Wipe the ferrule on a dry area of the lint-free towel. 4. - Page 16 Table 4: Pin Assignment Signal Description power ground power ground Busy busy output: low = idle, high = switching data line 0 input, least significant bit (LSB) Error reset error output, low = normal, high = switch mechanism position check failed (channel position is verified when the SK switch is reset) data line 1 not connected...

Page 17: Fiber Exit
All transistor-to-transistor logic (TTL) inputs and outputs are pulled high to 5 V DC through 10 K ohm resistors. For inputs, the maximum low level output is 0.8 V, and the minimum high level is 2.0 V. For outputs, the maximum low level output is 0.5 V, and the minimum high level is 4.0 V. Fiber Exit The fibers always exit from the back of the unit (Figure 5), but the order can vary with the unit. -
Page 19: Operating And Maintenance Instructions
Operating and Maintenance Instructions External Description The top and side views of the SK switch module are shown in Figure 6. Figure 6: Top and Side Views of the SK Switch Connections The way that the SK switch interfaces with the input/output lines of a typical host controller is shown in Figure 7. -
Page 20: Pin Functional Description
Figure 7: Typical Controller Connections Pin Functional Description Data Lines (D0 to D6) Valid channel numbers are strobed in through the data lines on high-to-low transitions of the /Strobe line. When a new channel is strobed in, the SK switch immediately selects the channel. The channel number is represented as a binary number present on the data lines having the values listed in the channel address in Table 5. - Page 21 Table 5: Channel Address Table /Reset channel # 0 (reset) The value 0 indicates that the input is set low (for example, <0.8 V DC); the value 1 indicates that the input is set high. For example, to select channel 9, D3 must be set high and the rest of the data lines must be set low.

Page 22: Reset Input Line
If the test fails, the Error line goes high and stays high until a self-test operation is evoked again (assuming the self-test passes on the next attempt). The error most often indicates a mechanical fault. For more information, contact JDS Uniphase. Timing When a channel address is strobed in from the data lines, the reset command is strobed in from the /Reset line. -
