The Juniper Networks Optical Inline Amplifier is a stand-alone erbium-doped fiber amplifier (EDFA) with
dual AC or DC power supplies. The optical inline amplifier (ILA) supports bidirectional optical inline
amplification. The optical ILA provides periodic amplification of a dense wavelength-division multiplexing
(DWDM) signal to enable long-distance transmission as it propagates along the fiber-optic cable. Optical
ILAs are typically placed between 50 miles (80 km) and 62 miles (100 km) apart along the length of the
fiber. They are used in conjunction with the integrated photonic line cards (IPLCs) that are installed in the
Juniper Networks PTX3000 Packet Transport Routers. An optical ILA connects to an IPLC through the
LINE IN and LINE OUT LC port connectors on the front panel. It also connects to other optical ILAs through
the same LC port connectors.
The optical ILA operates with redundant hot-swappable pluggable power supplies that are either AC or
DC. The optical ILA can be managed by using Connectivity Services Director (CSD), or by using the CLI
console commands. The optical ILA does not run the Juniper Networks Junos operating system (Junos
OS).
Starting with Junos OS release 17.1, you can control and manage optical inline amplifiers (ILA) over the
optical supervisory channel (OSC) of the PTX3000 integrated photonic line system. For information about
