Digisol L2 Dual Stack 40G Intelligent Fiber Switch-DG-CS4626F

Product Type & Class
It is a Layer‑2 (L2) intelligent fiber switch with dual‑stack support, intended for aggregation/access in networks (data center or enterprise).

Port Configuration
Provides 24 × 10 GbE (10 Gigabit Ethernet) SFP+ fiber ports plus 2 × 40 GbE QSFP fiber uplink ports.

Dual Stack Support
The “dual stack” refers to IPv4 + IPv6 support, allowing operations under both protocols. (Though exact IPv6 features are not detailed in what I saw, dual stack is standard in this class.) The product label mentions “Dual Stack.”

Redundant Power Supply
It supports built‑in redundant AC & DC power supply options to suit different environmental / deployment requirements.

VLAN and Enhanced VLAN Features
Strong support for VLANs — includes standard VLAN, Voice VLAN, Q‑in‑Q, N:1 VLAN Translation, etc. This allows flexible segmentation of network traffic.

Quality of Service (QoS)
Comprehensive QoS management capability is provided, allowing traffic classification, bandwidth control (throttling or guaranteeing), prioritization, etc.

Reliability / Redundancy Features

• Supports Ethernet Ring Protection Protocol (G.8032) for ring topologies and fast link failover.

• Dual power supplies contribute to high availability.

Security & Access Control
Offers “intelligent security control” (though detailed features not fully listed in summary). Likely includes ACLs, port security, etc., as per class.

OAM (Operations, Administration, Maintenance)
Built‑in OAM to assist with monitoring, fault detection, performance measurement — which is important for fiber networks.

Full Optical Ports
The switch is “full optical port” — meaning all ports are fiber/SFP or QSFP — no copper RJ‑45 ports. This suggests suitability for long‑distance or fiber backbone environments.

Green / Energy Efficiency
It uses “advanced green environmental protection technology.” While specific features (like IEEE 802.3az or low power modes) weren’t detailed in the summary, this means it is optimized for energy savings.

High Bandwidth Uplinks
With 40Gbps QSFP uplink ports, the switch is capable of handling high traffic volumes, aggregating multiple 10G links or connecting to core network or high‑speed servers.

Usage Scenarios
It is targeted for both general network (enterprise, campus) and data center networks where fiber interconnect, high throughput, and redundancy are important.

Scalability & Manageability
The features like QoS, VLAN translation/N:1, OAM, dual dual‑stack, redundant power help this switch scale and be managed in complex network topologies. Ease of management is advertised.

Cost & Positioning
Marketed as a “low‑cost” solution relative to full L3 or higher‑end chassis switches, but still offering many enhanced L2+ features. So good cost‑performance for deployments needing fiber‑based high throughput without full L3 routing.
