Tellabs ONT 180C Optical Network Terminal (GPON)

The Tellabs ONT 180C Optical Network Terminal is a GPON ONT that provides 8-ports of Gigabit Ethernet connectivity that is a scalable and smart choice for the new enterprise LAN. This evolutionary ONT, which supports the modern office and extended campus environments, can be integrated inside office furniture, secured to a wall, mounted underneath a desk or just be free-standing at a desktop. All 3rd millennium IP-based enterprise services and applications can be delivered, including voice, video, high-speed data, wireless, security, access controls and building automation.

Tellabs Gigabit Passive Optical Network (G-PON) technology is based on the International Telecommunications Union (ITU) standard ITU-T G.984 and provides asymmetrical 2.5Gbps downstream / 1.25Gbps upstream transmission, over single-mode fiber optic cabling infrastructure.

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 180C ONT supports auto-discovery mechanisms, can be quickly provisioned using global templates and wizards, and offers smart troubleshooting tools, all of which allow for speedy moves, adds and changes for everyday operations.

Powering Options

Tellabs 180C ONT 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. For local powering option, the Tellabs PSU BBU unit with monitoring can be used as a local battery back-up. The ONT180C has both Phoenix and Molex connectors for power.

Power over Ethernet (PoE)

For Power over Ethernet (PoE), IEEE 802.3af PoE, PoE+ IEEE 802.3at (Class-4 negotiations) and IEEE 802.3bt (4PPOE) can be selected. The ONT can support 8-ports of 4PPoE supporting 802.3af/at/bt. The maximum PoE power when local powered is 140 watts and the maximum PoE power when remote powered is 100 watts. Pre-standard 802.3 PoE is not supported (legacy Cisco inline power).

Mounting Choices

Tellabs 180C ONT is designed and tested for a wide variety of mounting scenarios. The 180C ONT can be integrated inside office furniture, secured to a wall or underneath a desk or just be free-standing on a desk top. There is an optional plenum bracket available if mounting in the above ceiling space.
