Channel A and Channel B of the 7705DS, these power values will subsequently be referred to as the Remote Launch Powers. Next, measure the optical power before Channel A and Channel B of the 7707BPX as shown in Figure 1-4. Verify the system complies with the following two formula: Remote Launch Optical Power Channel A-15 ≤... -

The back reflection between an optical Fiber and air is –15dB. To avoid Back reflection issues, measure the optical power being transmitted from Channel A and Channel B of the 7707BPX as shown in Figure 1-5. Set the 7707BPX’s optical threshold to: Optical Threshold A= Optical Power Meter Reading –12... -
Page 9: Installation
7707BPX Optical Bypass Protection Switch INSTALLATION The 7707BPX comes with a companion rear plate that has three SC/PC (shown), ST/PC or FC/PC optical connectors and a six pin terminal strip. For information on mounting the rear plate and inserting the module into the frame see the 7700FR chapter section 3. -
Page 10: Gpio I/O
7700 MultiFrame Manual 7707BPX Optical Bypass Protection Switch 2.1. GPIO I/O A 6-pin High Density D connector labeled GPIO contains 2 GPI inputs and GPO relay contact output. GPI’s: The two top pins on the 6 pin terminal strip are used for two General Purpose inputs (GPI). The GPIs can be configured as active high or low by setting DIP switch 3. -
Page 11: Care And Handling Of Optical Fiber
Never look directly into an optical fiber. Non-reversible damage to the eye can occur in a matter of milliseconds. The laser modules used in the Evertz fiber optic modules are Class I, with a maximum output power of 2mW, and wavelengths of either 1310 nm or 1270 to 1610 nm. -
