Tellabs ONT 202 Optical Network Terminal (XGS-PON)

The Tellabs ONT 202 Optical Network Terminal offers two multi-gigabit Ethernet options for 1G, 2.5G, 5G and 10G speed connectivity over a 10-Gigabit symmetrical XGS-PON network.

Driven by the exponential thirst for bandwidth, Tellabs Gigabit Passive Optical Networks are seamlessly evolving to the next generation standard called XGS-PON, which is based on ITU-T G.9807 and provide cost-effective symmetrical 10Gbps downstream and 10Gbps upstream capacity.  Tellabs XGS-PON Optical LAN requires different fiber optic transceivers in the Optical Line Terminal (OLT) cards, and different Optical Network Terminal (ONT) devices, but otherwise uses the same OLT and single-mode fiber optic cabling infrastructure as Tellabs GPON Optical LAN.

  • 10-Gigabit Symmetrical Passive Optical Network (ITU G.9807.1 XGS-PON)
  • Two multi-gigabit Ethernet ports supporting 10G/5G/2.5G/1G and the other supporting 2.5G/1G/100M
  • Power over Ethernet (PoE) 802.3af, 802.3at, 802.3bt (4PPoE), and UPoE with 60W per port capacity
  • Local and remote powering choices are supported with both Phoenix and Molex connectors

Connecting Wi-Fi Access Points

The Tellabs FlexSym ONT202 provides flexible choices for connecting modern wireless access points, including IEEE 802.1ax Wi-Fi 6 and future wireless technologies, over a fiber-based enterprise network. In a traditional network design, these bandwidth hungry Wi-Fi devices demand multiple point-to-point gigabit Ethernet connections 100m (300ft) back to the telecommunications rooms. With the Tellabs FlexSym ONT202, the unlimited capacity of fiber cabling can be pushed deep into buildings and across extended campus, with multi-rate Ethernet for 1G, 2.5G, 5G and 10G positioned near the Wi-Fi endpoints provide the optimal bandwidth needed.

IP Camera Backhaul

Additionally, Tellabs FlexSym ONT202 industrial temperature range and high-power Power over Ethernet (PoE) capacity makes it well suited for outdoor IP surveillance camera support where higher resolutions cameras such as HD and 4K monopolize bandwidth. The ONT202’s high power PoE is also important to support the camera heaters and Pan Tilt Zoom (PTZ).

Centralized Management

All features and functionality can be defined in software and dynamically allocated, based on real-time needs. Being controlled by the Tellabs® Panorama™ PON Manager helps speed installations and daily operations. Centrally controlled by the Tellabs Panorama PON Manager, the Tellabs FlexSym ONT202 supports auto-discovery mechanisms, can be quickly provisioned using global profiles, and offers smart troubleshooting tools, all of which allow for speedy moves, adds and changes for everyday operations.

Power over Ethernet (PoE)

The ONT202 supports Power over Ethernet (PoE) standards IEEE 802.3af, 802.3at, 802.3bt (4PPoE), and Cisco UPoE. It can deliver up to 120W (2x60W) of PoE power when powered by the 150W AC wall adapter utilizing the Molex 8 pin connector and up to 60W of PoE power when powered by the 75W AC wall adapter. The ONT202 supports up to 90W of PoE power when powered by remote power.

Powering Options

The Tellabs FlexSym ONT202 powering options include both local AC and remote DC. For local AC power, power adaptors are used to transform 120 AC power from the wall plug to 48 DC power delivered to the ONT. For the remote DC power option, a centrally located bulk rectifier can be used, and 48 VDC power is delivered over CATx cables or new hybrid fiber/copper cables. Remote powering option uses a centrally located bulk power plant, emergency power and bulk battery back-up.

Mounting Choices

The ONT202 supports industrial temperature making it an ideal choice for outdoor mounting in NEMA enclosures for connecting outdoor Wi-Fi and IP surveillance cameras. It is also plenum rated and has integrated fiber management. It has pre-existing mounting holes for easy mounting on double gang electrical box, Tellabs ONT140C mounting plate and options for DIN rail rack mounting.
