The PM5377-FGI is a telecommunications product used to provide optical line protection for high-speed communications systems. The device provides a reliable and redundant system for optical duplex transmission, allowing for unidirectional or bidirectional line transmission. It provides optical protection against physical damage such as cable cuts, and against failure of an optical transceiver or multiplexer.

Application Field

PM5377-FGI is mostly used in high-end communications systems, such as backbone networks, optical access systems, and metro networks. It is applicable in areas with high-speed IP/Ethernet transmissions and is suitable for optical line facilities such as WDM/CWDM/DWDM and 10G/100G/200G. The device is also able to provide for a balance of rate and redundancy, allowing for seamless integration with the communications systems, regardless of their size or complexity.

Working Principle

The working principle of the PM5377-FGI is based on the concept of optical line protection. The device provides a full-duplex optical protection scheme through its two optical fibers. It also provides a signal redundancy and is able to switch automatically to a working channel in case of a signal failure or interruption. The device is also capable of signal and back-up channel failure detection and can switch automatically to one of the two fibers depending on the signal loss. The device is able to detect a signal failure in either the signal channel or the back-up channel and will switch to the remaining healthy one.

The device features two sets of electrical ports which can be used for Ethernet uplink and management. The uplink ports can be used to provide remote management access to the unit, as well as for monitoring, status checking, and remote diagnostics for the optical lines. The device was designed to provide a reliable and redundant system for optical duplex transmission, allowing for unidirectional or bidirectional line transmission. It provides optical protection against physical damage such as cable cuts, and against failure of an optical transceiver or multiplexer.
