Cisco’s family of 10-Gbps symmetrical passive optical network (XGS-PON) Optical Network Terminals (ONTs) delivers flexible, high-performance broadband connectivity for a wide range of fiber-to-the-premises use cases, including residential spaces, Multidwelling Units (MDUs), Small Office/Home Office (SOHO), and Small to Medium-Sized Business/Enterprise (SMB/SME) environments. Cisco® ONTs enable cost-effective, reliable, high-density fiber deployments designed for efficient serviceability and management at scale.
Cisco 10G Routed PON ONTs are fully compliant with the XGS-PON ITU-T G.9807.1 standard and support symmetrical 10-Gbps downstream and upstream optical connectivity via an SC/APC optical connector, helping ensure support for both current and future networking needs. With integrated XGS-PON optics, MAC, and Ethernet switching capabilities, Cisco PON ONTs help network operators optimize the network’s Total Cost of Ownership (TCO) by reducing edge transport, switching, and routing costs, as well as minimizing footprint and power consumption. Cisco PON ONTs, in conjunction with Cisco routed PON modules, are an ideal end-to-end solution to support today’s cost-effective, agile, and diverse networking requirements. An example of a PON deployment using Cisco ONTs and Optical Line Terminals (OLTs) is shown below.

Example of a Passive Optical Network (PON)
ENC-10G-ONT-10, the XGS-PON ONT for high-speed single-port RJ-45 deployments
This small, slim low-noise desktop ONT is optimized to be deployed in a wide variety of indoor SMB/SME environments. It delivers secure, high-speed broadband access with flexible deployment in metro and business settings. The ENC-10G-ONT-10 comes with built-in XGS-PON optics and MAC, an Ethernet switch, and one RJ-45 interface that supports up to 10 Gbps.

ENC-10G-ONT-01PR, the XGS-PON ONT for outdoor deployments
Purpose-built for secure, reliable broadband service delivery in the most demanding outdoor environments, the ENC-10G-ONT-01PR is the ideal weatherized access device solution for residential and SOHO applications. The small, slim, ruggedized design enables this ONT to be deployed in a wide variety of outdoor environments and comes with built-in XGS-PON optics and MAC, an Ethernet switch, and one 2.5-Gbps RJ-45 electrical port. The ENC-10G-ONT-01PR is intended to be powered by PoE but can also be powered with a DC power supply (not included).

Scaling up bandwidth
Over the past several decades, PON has proven to be highly effective for fiber-to-the-premises applications. With bandwidth requirements projected to increase tenfold over the next decade due to multiple factors, including the growing proliferation of AI, the data bandwidth provided by legacy asymmetrical Ethernet PON (EPON) and Gigabit PON (GPON) technologies is no longer sufficient. This accelerating demand is driving operators to adopt next-generation XGS-PON solutions to help ensure that they stay ahead of evolving market needs and have the high-performance connectivity that demanding subscribers expect.
End user benefits
Positioned across the spectrum of end-customer use cases, these ONTs enable network operators to efficiently create, deploy, manage, and maintain cost-effective broadband and voice services. Cisco 10G Routed PON ONTs are optimized to minimize physical space and noise levels, and are tailored for flexible deployments across diverse environments, ranging from outdoor installations to constrained office cubicle environments. Supporting high-speed Gigabit broadband, advanced voice features, and a variety of port configurations, Cisco 10G Routed PON ONTs enable operators to maximize resource utilization, accelerate new service rollouts, and enhance both end user experiences and network operator competitiveness in today’s fast-moving market.
PON single optical fiber connectivity
Cisco’s 10G Routed PON ONT family of solutions provides XGS-PON-compliant functionality, where symmetrical 10-Gbps data is transmitted in both the upstream and downstream directions over a single strand of single-mode optical fiber. The use of one optical fiber enables network operators to minimize fiber and deployment costs and maximize the return on investment of deployed fiber. The ONT’s optical receiver receives the downstream data on the 1577 nm wavelength, while its optical transmitter transmits upstream data on the 1270 nm wavelength. Cisco 10G Routed PON ONTs are compliant with the N2 optical link budget per the ITU-T G.9807.1 standard at up to a 1:64 split ratio over links spanning up to 20 kilometers. Fully compliant with the XGS-PON standards, multiple generations of PON services can interoperate, coexist, migrate, and provide differentiated service levels over the same optical fiber network without contention.
Convergence of PON and Ethernet
Cisco’s Routed PON Modules and PON ONTs enable network operators to unlock more value from their networks by making available converged PON and Ethernet services within a single router. Customers can easily add new services without the need for costly dedicated OLT chassis, opening up unparalleled choice and control over service offerings, increased service velocity, exceptional interoperability and scalability, optimized space and energy consumption, and lower costs.
Compliant with the industry-standard Optical Network Unit (ONU) Management and Control Interface (OMCI), Cisco 10G Routed PON ONTs can be managed remotely in band when an optical link is established with Cisco Routed PON Modules. For example, new services can be launched and firmware upgraded, enabling operators greater ease and flexibility when managing large, deployed fleets of ONTs. For the ENC-10G-ONT-14A, TR-69 is used for the management of gateway mode and ATA attributes.
