Page 7: Installation
7707AR-A Multi-Channel Analog Audio Fiber Receiver INSTALLATION The 7707AR-A series modules come with a companion rear plate that has analog audio connections and an SC/PC (shown), ST/PC or FC/PC optical connector. Each version provides analog audio connections via multi-pin removable terminal blocks. For information on mounting the rear plate and inserting the module into the frame see the 7700FR chapter section 3. -
Page 8: Audio Connections
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 a wavelength of 1310nm or 1270 to 1610nm. -
