The ONT180CHP consumes a maximum of 7.5 Watts of power with no PoE devices connected to it. The amount of PoE power available from the ONT180CHP depends on the DC power input to the ONT (subject to the class limitations and apportionment by port shown in the Specifications table below).

Note: Input circuits need to be compliant with NEC article 726 (CEC article 16-200) requirements for Class 2 power limited circuits. The combiner/aggregator such as EPS-4X-Combiner and Alpha Aggregators allow for multiple 100VA network-powered circuits. They are UL62368/CSA C22.2 compliant combiner/aggregator.

Tellabs ONT180CHP - Inside (and Outside) the Box

The ONT180CHP box contains

• ONT180CHP – desktop Optical Network Terminal unit (no power supply)
• Phoenix-type pluggable terminal connector (5.08 mm pitch 2P)

If multiple ONT180CHPs are ordered, or optional accessories are ordered along with the ONT180CHP, they may be packed in the same shipping container or be shipped separately. The following table gives the 180CHP part numbers and accessories associated with the 180CHP.

Powering Options

The ONT180CHP can be powered utilizing one of three methods.

1. Using 140W AC adapter 
2. Combining the power outputs from a Class 2 power source

• Combining the power outputs from a Class 2 power source will require the addition of a combiner/aggregator to increase the output power to the required 200 or 300 Watts and still remain in compliance with warranty and safety requirements.

3. Supplying Pulse power from a Class 4 Power System

• A Class 4 Pulse Power System transports power through a Pulsed Current waveform. Pulsed Current comprises short duration pulses (e.g., 3 ms), where each pulse contains a power ON and power OFF period. Delivering power in this way allows the Pulse Power system to detect faults and stop power transmission almost instantly, protecting against inadvertent contact with the power conductors.  Pulsed Current can supply DC power up to 2KM.  

Warning: Any ONT being supplied greater than 100W of DC power must use a power system that either has a certified NEC-compliant class 2 combiner or meets the NEC class 4 Fault Managed Power System as defined by Article 726 of the 2023 National Electrical Code (NEC).

Tellabs has many locally powered sites and can recommend the correct powering option for the number of ONTs and power requirements based on the number of attached PoE devices. Local-powered options do not require electricians for any of the wiring or installation. 

Outside the box

A reusable-adhesive label with the ONT serial number and barcode printed on it is attached to the outside of the box. This label can be peeled off the box and placed on the ONT case or any other suitable place near the ONT so that the serial number can be seen easily when the ONT is attached to a wall, underneath a desk, or is in some other location in which the permanent label on the bottom surface of the ONT is not readily accessible.  This allows rapid ONT location and troubleshooting without having to remove the ONT from the bracket.
