Page 7: Installation
7700 MultiFrame Manual 7707BPX-TR Optical Bypass Protection Switch INSTALLATION The 7707BPX-TR comes with a companion rear plate that has six SC/PC (shown), ST/PC or FC/PC optical connectors, a DB-9 type connector, and a six pin terminal strip. For information on mounting the rear plate and inserting the module into the frame see section 3 of the 7700FR chapter. -
Page 8: Gpio I/O
7700 MultiFrame Manual 7707BPX-TR Optical Bypass Protection Switch TRANSMIT OUTPUTS A, B: The dual SC/PC (shown) ST/PC or FC/PC female connectors are the optical outputs from the splitter/combiner for the outgoing signal path. The A connector is for the Main Output and the B connector is for the Standby Output. -
Page 9: Cit Interface
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. -
