Site Preparation

The installation must seek to balance user preference with the environmental, power, and cabling requirements of the ONT and any subtending equipment. The following items need to be planned for prior to installing the ONT.

Physical Mounting Options

The ONT202 supports industrial temperatures and humidity and is also plenum rated. It can be used in a wide range of applications. The ONT can be installed in most any location including desktop, indoor surface and electrical gang box mount, outdoor NEMA enclosures, ceiling plenums and racks in communication closets. The ONT design, optional mounting hardware and accessories provide installation options to fit most needs.

Optical Fiber Location

When selecting the installation location, it is important to consider the location of the fiber cable drop. Because fiber cables are not typically spliced or terminated in the field, it is important that the cable is long enough to reach the ONT. It is better for the cable to be too long than for it to be too short by any amount. For this reason, there is normally excess fiber to manage after the connections have been made. The ONT202 is uniquely designed with an integrated fiber management system to store and protect this slack from accidental damage.

Environmental Requirements

The ONT202 operates in temperatures ranging from -40° to 140°F (-40° to 60°C) with relative humidity ranging from 10% to 95%. If deployed outdoors, the unit must be installed in a NEMA outdoor rated enclosure.

Power Requirements

The FlexSym ONT202 requires 52-57 VDC at up to a maximum of 2.78 amps (at full PoE load). DC power can be obtained from one of the two optional AC adapters at the installation location, or from a central remote bulk 54-volt DC power supply. The amount of power delivered by the ONT varies according to the powering option selected. Each powering option requires planning related to the accessories required and power source location.

The ONT202 consumes about 7 Watts of power with no PoE devices connected to it. The ONT202 supports Power over Ethernet (PoE) standards IEEE 802.3af, 802.3at, 802.3bt (4PPoE), and Cisco UPoE. The amount of PoE power available for PoE depends on the DC power input (subject to the class limitations and apportionment by port) shown in the specifications table. It can deliver up to 120W (2x60W) of PoE when powered by the 150W AC wall adapter, up to 60W of PoE power when powered by the 75W AC wall adapter, and up to 90W of PoE power when remotely power.

To use an AC adapter, an AC outlet must be within about eight feet of the intended installation location.

To use remote power, a DC cable from the remote bulk DC power supply to the ONT is required. The DC cable is typically routed alongside the optical fiber cable. Composite cables are available that combine the optical fiber and DC power wiring inside a single jacket.

Warning: Do not bend the fiber optic cable to a diameter smaller than 7.5cm/3 inches. Doing so may damage the fiber or prevent the signal from passing through properly.

Note: The AC adapters and AC line cords are optional accessories, available from Tellabs separately and at extra cost. Contact your Tellabs sales representative for details and ordering information.

Tools and Supplies

The tools and supplies needed for a ONT202 installation vary depending on the location and type of installation. The items listed assume that the optical fiber cable drop (and remote bulk DC power cable, if used) are already installed.

Tools

The following list of tools should cover the typical ONT202 installation:

• Screwdrivers or driver bits
  • Small slot screwdriver (1/8 inch) for attaching DC power wiring to a DC power connector pigtail (for installations using remote bulk DC power or the alternate AC adapter)
  • Screwdrivers or driver bits to fit the wood or machine screws, dry wall anchor screws, or masonry anchor screws that will be used in mounting the ONT to a wall or other surface
  • Medium slot screwdriver
• Wire cutter/stripper (for installations using remote bulk DC power or the alternate AC adapter)
• Power drill and drill bits sized appropriately for screw pilot holes, and drywall and masonry anchor holes (sizes required will depend on fastener selection)
• Digital multimeter with test leads (a DMM with only basic functions will do)
• Optical Power Meter
• Fiber Optic Inspection Microscope
• Multi-purpose fiber optic cleaning tool with bulkhead adapter

Supplies

The following list of supplies should cover most typical ONT202 installations (supplies are locally sourced):

• Fasteners
  • Select screws, drywall anchors, and masonry anchors of the appropriate size for the weight of the ONT and optional wall mounting or plenum bracket. Ensure that the heads are large enough so they do not pull through the mounting holes of the bracket.
• DC power connectors
  • Extra Phoenix-type pluggable terminal connectors (5.08 mm pitch 2P) to fit the ONT DC 54V power connector (one connector is packaged with the ONT)
  • Molex connectors (8-pin) to fit the ONT UPS connector
• Cable ties (Nylon and Velcro)
• Vinyl electrical tape
• Sharpie or other fine-point permanent marker

Unpacking and Inspection

The Tellabs ONT and related accessories may arrive in a single shipping container, or in multiple containers. When unpacking the boxes, check each item against the installation work order and for obvious shipping damage. If a shortage or damage is found, contact the Tellabs Warranty/Repair and Return Center immediately.

Inside the Box

The FlexSym ONT202 box contains:

• FlexSym ONT202 - desktop Optical Network Terminal unit (no power supply)
• Phoenix-type pluggable terminal connector (5.08 mm pitch 2P)
• Universal ONT DIN Rail Mounting Bracket (includes two screws)

Outside the Box

A reusable-adhesive label with the ONT serial number (and barcode representation) printed on it is affixed to the outside of the box. This label can be peeled off the box and placed on the ONT case or other suitable place near the ONT. This can be used to provide serial number visibility if the permanent label on the bottom surface of the ONT is hidden. This can occur if the ONT is attached to a wall or underneath a desk or other surface. The serial number may be needed to provision the ONT using the Element Management System (EMS).
