Tellabs ONT 140C Optical Network Terminal (GPON)

The Tellabs ONT 140C Optical Network Terminal provide high-density Gigabit Ethernet connectivity that is a scalable and smart choice for the new enterprise LAN. This ONT supports the modern office and extended campus environments, and can be integrated inside office furniture, secured to a wall, mounted underneath a desk or just be free-standing on a desktop. All enterprise services and applications can be delivered, including voice, video, high-speed data, wireless, security, access controls and building automation. Like all Tellabs ONTs, the Tellabs 140C ONT provides simple, smart and scalable gigabit-speed services in all enterprise LAN environments, including government, financial, education, healthcare and hospitality.

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.

Advanced IP and Ethernet

Uses industry-leading software-defined traffic management, security, provisioning and quality of service mechanisms.


The Tellabs 140C ONT supports enterprise VoIP connectivity with the latest unified communications systems such as Avaya and Cisco Unified Communications Call Manager can be delivered over fiber.


Supports all enterprise IP-based video traffic (e.g., entertainment, surveillance, conferencing)


The Tellabs ONT140C is designed with local power, local Battery Backup Unit (BBU) and remote powering options. Remote powering is supported using a centrally located bulk power plant, emergency power and bulk battery back-up over composite single mode fiber (greenfield).

Power over Ethernet (PoE)

Both IEEE 802.3af PoE and high-power PoE+ IEEE 802.3at, including Class-4 negotiations can be selected on per port basis. The maximum PoE power is 60 watts, spread across all four Ethernet ports.


Tellabs 140C ONT mounting can be located above the desk or below the desk, within the raceways of modular cubicle work environments or ONTs can be wall mounted. Where security is a priority, lockable enclosures can be used for any of the above-listed locations. They can also be mounted in zone boxes, plenum space and in raised floors.
