Fiber-To-The-Home (FTTH)

Fiber-To-The-Home (FTTH) has always been an attractive option for Internet access. It has all the benefits of optical fiber. It provides a future-proof network by avoiding the hassle of having to upgrade from ADSL to XDSL, or digital coax to digital wireless. It is highly reliable because it eliminates all of the problems with electromagnetic interference. Moreover, it is immune to lightning and other transients. These properties of fiber lead to the lowest possible power and operational costs, such as maintenance, provisioning and facilities planning.

This switch and a standard CPE (Customer Premises Equipment) form the key components of an ideal FTTH system, allowing a service provider to easily extend an Ethernet connection over optical fiber directly to a subscriber. This switch contains 24 100BASE-BX full-duplex single-fiber single-mode cable connections that run from the service provider’s central office (CO) directly to the subscriber’s CPE. Each single-mode fiber connection can be run up to a distance of 10 km from the CO.

The switch also provides two 1000BASE-T/SFP uplink ports for connections to other switches or routers at the CO. The SFP ports allow the switch to be located up to 70 km from the CO using 1000BASE-ZX transceivers, giving you the option of placing the switch either in the CO or anywhere along the path between the CO and the subscriber.

A CPE is a single-channel fiber-to-copper conversion unit. The CPE connects to the fiber cable from the CO and provides one standard 10/100BASE-TX RJ-45 Ethernet port for connecting to a subscriber’s residential gateway, PC, switch, or other network device using twisted-pair

SMC7824M/FSW specifications

The SMC Networks SMC7824M/FSW is a robust and versatile managed switch designed for small to medium-sized enterprises that require reliable networking solutions for their growing needs. This switch is part of SMC's commitment to providing innovative networking products that deliver superior performance and flexibility.

One of the main features of the SMC7824M/FSW is its 24-port configuration, which provides ample connectivity for a variety of devices within a network. The switch supports both 10/100 Mbps Fast Ethernet and 10/100/1000 Mbps Gigabit Ethernet connections, allowing for seamless integration of multiple devices ranging from legacy systems to modern high-speed applications. This flexibility is crucial for businesses looking to extend the life of existing equipment while still adopting new technologies.

The SMC7824M/FSW is equipped with advanced Layer 2 management capabilities, including VLAN (Virtual Local Area Network) support, which enables network administrators to segment traffic for improved performance and security. Additionally, it supports Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP), which ensures loop-free network topology and enhances network stability.

Another significant feature is the switch’s Quality of Service (QoS) functionality, allowing for prioritization of critical data traffic. This is particularly beneficial for voice over IP (VoIP) and video conferencing applications, where latency and jitter must be minimized to ensure optimal performance. With QoS, businesses can maintain high levels of service, even as network demands increase.

The SMC7824M/FSW also includes features such as port mirroring for traffic analysis and troubleshooting, Link Aggregation for increased bandwidth and redundancy, and an easy-to-use web-based interface for straightforward configuration and management. This ease of use makes it an excellent choice for IT administrators who may not have extensive networking experience.

In addition to its extensive feature set, the SMC7824M/FSW is designed with energy efficiency in mind. It complies with IEEE 802.3az Energy Efficient Ethernet standards, allowing it to consume less power during periods of low traffic, thus reducing operational costs.

In summary, the SMC Networks SMC7824M/FSW switch is a powerful solution that combines flexibility, advanced management features, and energy efficiency, making it an ideal choice for businesses looking to enhance their networking capabilities while remaining cost-effective. Its comprehensive set of features ensures that it can meet the demands of modern network environments.
