The IDM S328GF-24SFP 10G uplink aggregation switch operates between the access layer and the core layer: after front-end cameras, access control, PLCs, measuring instruments and other devices are uplinked over optical fiber, the IDM S328GF-24SFP 10G uplink aggregation switch completes equipment room fiber aggregation at the central equipment room side, and then uplinks to the core through 10G ports. Replacing multiple small-port switches plus standalone media converters with 24 Gigabit SFP optical ports is a direct way to reduce the number of devices and cabinet space usage on the equipment room aggregation side, and also meets the demand of government private network optical fiber communication solutions, smart mining communication solutions and security surveillance optical fiber aggregation solutions for centralized aggregation of fiber optic switches. As a professional media converter manufacturer and industrial Ethernet switch manufacturer, Raytrans continues to provide reliable product showcases and equipment support such as media converters and industrial Ethernet switches for various industries.
What Kind of Device Is the IDM S328GF-24SFP 10G Uplink Aggregation Switch?
The IDM S328GF-24SFP 10G uplink aggregation switch is a rack-mounted all-optical port aggregation-type fiber optic Ethernet switch that integrates 24 1000Mbps SFP fiber ports, 1~4 10G SFP Plus uplink ports and 8 10/100/1000BaseT(X) electrical ports in a single device. Its data switching mechanism is store-and-forward, its dimensions are 440mm (W) × 43.6mm (H) × 285mm (D), its weight is 4.6KG, and it uses a metal enclosure and a GB standard D-type power connector, allowing single-person rack installation. The positioning of the IDM S328GF-24SFP 10G uplink aggregation switch in networking is the aggregation node for distributed network access at the central equipment room side: the optical fibers of access-side devices are aggregated once in the equipment room, and the uplink side connects to the core switch through 10G ports, so there is no need to configure a standalone media converter or small switch for each fiber in the equipment room. As an aggregation-type product in the fiber optic switch category, this device is often used for aggregation layer solution demonstrations in product showcases.
How Do 24 Gigabit SFP Optical Ports Aggregate Front-End Fibers in the Equipment Room at Once?
24 front-end fiber links are aggregated and forwarded within the IDM S328GF-24SFP 10G uplink aggregation switch, so the equipment room no longer needs to configure a separate media converter or small switch for each fiber. The IDM S328GF-24SFP 10G uplink aggregation switch provides 24 1000Mbps SFP fiber ports, supports single-mode/multi-mode and single-fiber/dual-fiber options, and its interface forms are SC and LC. All ports provide non-blocking, wire-speed packet forwarding, with switching latency less than 1us, and cabinet space and supporting power supply are reduced accordingly. For projects that need a 24-port Gigabit SFP optical port switch, the optical ports, electrical ports and 10G uplink are integrated in the same rack-mounted device, making it easy to incorporate into product showcases and operation and maintenance lists in a unified manner; the same device can be used for equipment room aggregation in government private network optical fiber communication solutions, and can also serve as a standard aggregation node in aggregation layer optical fiber networking, adapting to the front-end aggregation requirements of security surveillance optical fiber aggregation solutions.
Why Do 1~4 10G SFP Plus Uplinks Keep 24 Channels of Burst Traffic from Congesting?
The uplink side of the IDM S328GF-24SFP 10G uplink aggregation switch provides 14 10G SFP Plus ports, facilitating high-speed uplinks and stacking. These 14 10G ports can directly connect to the core switch, and can also be used for interconnection and stacking between multiple aggregation switches; port rates cover 10/100/1000Mbps and 10000Mbps. When 24 Gigabit links generate burst traffic simultaneously, the 10G uplink ports still have margin to forward to the core layer, so the aggregation layer is unlikely to become the bandwidth bottleneck of the entire network. For smart city, electronic police and factory automation projects whose core side has already been planned at 10G, selecting aggregation equipment with 10G uplink specifications can match the core-side bandwidth, and it is also suitable as an aggregation node between the underground ring network and the surface core in smart mining communication solutions.
8 Gigabit RJ45 Electrical Ports Handle Local Access in the Equipment Room
The 8 Gigabit RJ45 electrical ports of the IDM S328GF-24SFP 10G uplink aggregation switch are used for local access in the equipment room, eliminating the need for an additional access switch. These 8 10/100/1000BaseT(X) interfaces support 10Mbps/100Mbps/1000Mbps adaptive, full-duplex/half-duplex adaptive and MDI/MDIX polarity adaptive operation, and can connect to network management terminals, servers or nearby electrical port devices in the equipment room; together with VLAN partitioning and access control lists, network management traffic and service traffic can be divided into different VLANs for isolated forwarding.

Typical Application Scenarios
Equipment Room Aggregation for Smart Cities and Tianwang Systems
In Tianwang system and smart city projects, the front-end sites are scattered across intersections, communities and industrial parks, and the trunk optical cables of each area aggregate the signals to the branch bureau or central equipment room. On the equipment room side, the Raytrans IDM S328GF-24SFP 10G uplink aggregation switch uses 24 Gigabit SFP optical ports to aggregate 24 area uplink fibers with one device, and then uses 10G SFP Plus ports to uplink to the core switch; SFP optical modules offer selectable distances from 20KM to 200KM, so that sites across districts and counties can also be incorporated into the same aggregation layer, forming an aggregation layer optical fiber networking for a well-structured government private network optical fiber communication solution and security surveillance optical fiber aggregation solution.

Front-End Aggregation for Security Surveillance and Electronic Police
Security surveillance and electronic police projects have high requirements for uplink bandwidth and link distance: high-definition video streams from checkpoints and electronic police sites are uploaded in a centralized manner, while park surveillance needs to backhaul the signals of dozens of cameras to the surveillance center. The Raytrans IDM S328GF-24SFP 10G uplink aggregation switch uses 24 Gigabit SFP optical ports to receive front-end optical cables, uses 802.1p QOS priority to guarantee the forwarding order of video services, uses single-mode 20KM optical modules for nearby sites, and selects 40KM, 60KM, 80KM, 120KM or 200KM modules for ultra-long-distance sites according to link length, making it the core aggregation equipment in security surveillance optical fiber aggregation solutions.
Industrial Ethernet Aggregation for Factory Automation and Building Automation
In factory automation scenarios, PLCs, robot control cabinets, visual inspection and energy consumption collection equipment make extensive use of Ethernet interfaces, and the distance between floors and workshops often exceeds the reliable transmission range of twisted pair. The Raytrans IDM S328GF-24SFP 10G uplink aggregation switch replaces long-distance copper cable with optical fiber; its metal enclosure and -20°C~70°C operating temperature adapt to the temperature fluctuations of workshops and power distribution rooms; STP, RSTP and MSTP spanning tree protocols and broadcast storm suppression give a solid basis for link redundancy and flooding control in production line networks, and it can provide seamless interfacing with industrial Ethernet switches and fiber optic switches in hybrid networking.

How to Select a 10G Uplink Aggregation Switch
When selecting a 10G uplink aggregation switch for a project, it is sufficient to check four items: number of access channels, uplink mode, link distance and environmental conditions. First, the number of optical ports: the number of front-end uplink fibers determines the number of Gigabit SFP optical ports, and the 24-port model is suitable for central aggregation in medium-scale areas; second, the uplink mode: when the core side is planned for 10G, select the uplink specification with 14 10G SFP Plus ports, and the interconnection or stacking of multiple aggregation switches also uses 10G ports; third, the optical module distance: select SFP modules and single-mode/multi-mode and single-fiber/dual-fiber options from six levels between 20KM and 200KM according to the on-site link length; fourth, the operating environment: field cabinets and unattended sites need to be checked item by item against the -20°-C70°C operating temperature, AC 90~264V wide-range voltage input and overload protection. As a media converter manufacturer and an industrial Ethernet switch manufacturer, Raytrans provides complete selection support for media converters, industrial Ethernet switches and fiber optic switches in its product showcase, helping smart mining communication solutions and government private network optical fiber communication solutions to be implemented.
The Raytrans IDM S328GF-24SFP 10G uplink aggregation switch is configured according to the common conditions of central equipment room aggregation and field cabinet deployment in the above four items, and can serve as the starting point for selection of the aggregation layer in smart city, Tianwang system, security surveillance, factory automation and building automation projects.
