TCX1000-ILA System Overview


TCX1000 Inline Amplifier Description

The Juniper Networks TCX1000 Inline Amplifier is a standalone erbium-doped fiber amplifier (EDFA) with dual AC or DC power supplies.The TCX1000-ILA supports dual optical inline amplification—two functionally separate amplifiers. The TCX1000-ILA provides amplification of a dense wavelength-division multiplexing (DWDM) signal to enable long-distance transmission over fiber-optic cable. The TCX1000-ILA is used in conjunction with the TCX1000-RDM20.

The TCX1000-ILA operates with redundant hot-swappable pluggable power supplies that are either AC or DC.

For more information on the TCX Series operation, features, and deployment examples, see the TCX Series Optical Transport System Feature Guide at

The proNX Optical Director is required for the proper operation of the TCX1000-ILA. For more information about configuring the TCX1000-ILA, see the proNX Optical Director User Guide and the proNX Optical Director Installation Guide at


The TCX1000-ILA does not run the Juniper Networks Junos operating system (OS).

Front Panel

The front panel of the TCX1000-ILA contains six LC port connectors, the ON/OFF button, the console and management ports, the system status LEDs, and the USB ports. Figure 1 shows the front panel of the TCX1000-ILA.

FRU Panel

The field-replaceable unit (FRU) panel of the TCX1000-ILA contains the fan modules and power supplies for the TCX1000-ILA. Figure 2 shows the FRU panel on the TCX1000-ILA.

Power supplies

The cooling system in the TCX1000-ILA consists of three 12.4-W fan modules. These fan modules can be hot-swapped—you do not need to power off the TCX1000-ILA or disrupt the functioning of the TCX1000-ILA to replace a fan module. The TCX1000-ILA has two 150-W power supplies, either AC or DC depending on your configuration. The power supplies need to be both AC or both DC. Only one power supply is required to power the device, while the second power supply provides redundancy.

TCX1000-ILA Component Redundancy

The following hardware components provide redundancy on the TCX1000-ILA models:

  • Cooling system—The TCX1000-ILA has three fan modules. Each fan module is a redundant unit containing one fan. If a fan module fails and the remaining fan modules are unable to keep the TCX1000-ILA within the desired temperature thresholds, chassis alarms are raised and the TCX1000 ILA can shut down.

  • The TCX1000-ILA ships with two power supplies that provide 1+1 redundancy. If one power supply fails or is removed, the second power supply balances the electrical load without interruption and still provides 1+1 redundancy while the failing power supply is replaced.

TCX1000-ILA Field-Replaceable Units

Field-replaceable units (FRUs) are components that you can replace at your site. The TCX1000-ILA FRUs are hot-removable and hot-insertable—you can remove and replace them without powering off the TCX1000-ILA or disrupting the TCX1000-ILA function.


Replace a failed fan module with a new fan module within 30 seconds of removal to prevent chassis overheating.

Table 3 lists the FRUs for the TCX1000-ILA and actions to take before removing them.
