Browse BWNFiber articles and product resources related to Hub.

A fiber distribution hub (FDH) is an outdoor secure cabinet that connects fiber optic cables and optical splitters in the outside plant part of a network. These fiber cabinets connect feeder and distribution cables via optical splitters in FTTx networks. Then, feeder cables meet inside with splitters that distribute the signal to the homes and businesses. A fiber distribution hub is an important part of a fiber optic network. It connects multiple fiber channels to achieve high-speed data transmission and data sharing.

Early connection cabinets were limited to bulky metal cabinets. These metal cabinets had limited user capacity. Today’s FDH solutions support higher subscriber counts and a smaller footprint. As a fiber distribution hub manufacturer and supplier, Bwnfiber offers a full line of scalable Fiber Distribution Hub (FDH) solutions. Our fiber hub cabinets are available in multiple sizes depending on the location in the network and the number of customers needing service. For example, our SJ-ODB-M18-B provides a safe and reliable way to route, distribute, and terminate fiber optic cables. In addition, we are committed to custom designs. Over the years, our fiber hub products have covered the USA, France, Germany, UAE, Argentina, South Africa, Brazil, etc.

Features of Fiber Distribution Hub

A fiber distribution hub connects multiple feeder and distribution cables to transmit data through optical fiber. It has the following features:

High-speed transmission

It can achieve high-speed data transmission, with transmission speeds reaching hundreds of megabits or even several Gbps.

Data Sharing

It can connect multiple fiber channels to achieve data sharing and improve network efficiency.

Scalability

It can achieve the expansion of fiber optic networks, and connect multiple fiber distribution hubs. Support more users as the subscriber base grows. For example, our SJ-OTB-SY-05 is an intelligent solution, they can be coupled together and connected to the building’s internal network.

Easy to Use

The fiber distribution hub adopts a modular design, which can be quickly installed. In addition, it facilitates technicians’ troubleshooting, routing, switching, connecting, and repairing the network components inside.

Applications for FDH Cabinets

Fiber distribution hubs are widely used for high-speed data transmission and data sharing is required, such as data centers, enterprises, schools, hospitals, etc. In data centers, fiber hubs can achieve high-speed data transmission and data sharing between servers. In enterprises and schools, it can achieve data sharing and collaborative work between different departments. For example, to meet the exacting requirements of indoor settings, such as enterprises and commercial establishments, our SJ-OTB-SY-18 accommodates up to 96 fusions and offers space for 64 adapters. While in hospitals, fiber optic hubs can achieve high-speed data transmission and data sharing between medical devices.
