15 ortel a division of emcore data sheet, rev. 0 march 6, 2003 system 8000 fiber-optic interfacility links system 8000 redundancy system 8000 provides multiple redundancy options. the standard offerings are single thread, 1:1, and 1:2. the 1:1 and 1:2 configurations offer two modes of redundancy switching: automatic and manual. automatic mode in this mode, internal sensing and control provides automatic switching to the backup link in case of any failure in the optical system. if the laser temperature alarm or laser optical power alarm is detected at the fiber-optic transmitter, the faulty transmitter is shut off. in the 1:2 redundancy scheme, if these conditions are detected, the switch position is changed to select the backup link. the fiber-optic receiver then detects loss of received optical power and the output is switched to the backup link. if the fiber-optic cable containing the fiber for the primary link is broken, the fiber-optic receiver detects loss of received optical power and the output is switched to the other channel. the switching due to receiver failure works independently of the external monitoring and control (m and c) system only for the 1:1 configuration. for the 1:2 version, the exter- nal m and c must switch the input to the backup trans- mitter. manual mode when this mode is selected, automatic switching to the backup link is turned off. this mode can be selected remotely through the m and c system or it can be selected locally by pressing the auto-off button on the front panel of the status and control plug-in on the chassis. figure 1. system 8000 redundancy mode configurations
