What is ONU?

An optical network unit (ONU) is used on the user side and designed to meet the requirements of the broadband access network. It provides high-speed internet access, voice, IPTV/CATV, and Wi-Fi service. This article provides some knowledge about ONU.
What is ONU?
ONU is the optical terminal device in the EPON (ethernet passive optical network) fiber access network, which provides users with multiple service interfaces. The network side of ONU is the optical interface (PON port, SC adapter), and the user side is the electrical interface (RJ45, CATV female).
An ONU is divided into an active optical network unit and a passive optical network unit. The active optical network unit ONU is mainly used in the integration of the three networks. Passive optical network unit ONU is a user-side device of a GEPON (gigabit passive optical network) system and is used to terminate a service transmitted from an OLT through an EPON (passive optical network).

How Does ONU Work?
An ONU converts optical signals to electrical signals via a fiber optic cable. An ONU organizes and optimizes different types of data coming from customers to efficiently send it upstream to the optical line terminal (OLT).

Features and Benefits
ONU provides dual mode, plug-and-play, auto-detecting, auto-configuration, auto firmware upgrade, supports 802.11n WiFi (2T2R) function, rich QinQ VLAN functions, NAT, firewall function, IPv4 and IPv6 dual stack. In addition, ONU provides a high bandwidth, high reliability, high flexibility, low cost, and easy management.

Applications
ONU is used in FTTH access networks, telecommunication networks, local area networks (LAN), data centers, etc.
Conclusion
ONU provides high-performance forwarding capabilities to ensure an excellent experience with VoIP, Internet, and HD video services. ONU provides high bandwidth, high flexibility, high stability, and high quality of service (QoS). Sun Telecom specializes in providing one-stop total fiber optic solutions for all fiber optic application industries worldwide. Contact us if any needs.

The Ultimate Guide to Business Router

图片
The business router provides Internet access for home and office and often connects two or more computer networks. It helps to manage network bandwidth, segmentation, security, and routing policies. This article provides a complete guide to the business router. What is a Business Router? A router is a device that connects two or more network devices. It acts as a gateway between networks. It is an intelligent network device that reads the address in each data packet and then decides how to transmit it. The business router is a device used to manage many terabits of data flowing through and between internet service provider (ISP) networks. It is the largest and most powerful network router from the Internet backbone. A business router usually provides connections for typical home and office networks. Features and Benefits 1. The business router provides network, application, and security services on a single device 2. The business router provides hardware-based VPN access for r

400G ZR Coherent Pluggable Optics: Enable 400G for Next-Generation Data Center Interconnect (DCI) and Metro Network Solutions

图片
400G ZR coherent pluggable optics plays a vital role in enabling the next-generation data center to interconnect (DCI) and metro network solutions to meet the bandwidth requirements of today and tomorrow. It reduces the cost and complexity of high-bandwidth data center interconnects and promotes interoperability among optical module manufacturers and providers. This article provides some knowledge about 400G ZR. What is 400G ZR? 400G ZR or 400ZR is an interoperable standard that enables the transmission of multiple 400GE payloads over Data Center Interconnect (DCI) links up to 80/120km using dense wavelength division multiplexing (DWDM) and higher-order modulation(16 QAM). It aims to secure an affordable and long-term implementation based on single-carrier 400G using dual-polarization 16 QAM (16-state quadrature amplitude modulation) at approximately 60 gigabaud (Gbaud). How Does 400G ZR Work? 400G ZR is an interoperable networking Implementation Agreement (IA) released by the Op
