Campus networks are changing fast—dense Wi-Fi, UHD surveillance, and fiber-first buildings are now the norm. The NS-S5750 Switches from Network-Switch are designed for those environments: a same-class, all-optical Campus Switches platform with SFP+ 10G uplinks and integrated Power-over-Fiber (PoF) distribution.
Unlike fixed-brand gear, the NS line ships as your product—front-bezel logo, exterior colorway, labels/packaging, and even pre-loaded software defaults (VLAN plan, QoS, AAA, Syslog/SNMP, uplink LACP templates). In short, you get the performance and resiliency of premium Ethernet switches while delivering a consistent, branded experience in every closet.
The NS-S5750 family mirrors the latest campus PoF switch architecture: 24 × 1G optical downlinks, 4 × 1G/10G SFP+ uplinks, and 24 power output ports over hybrid fiber-power cables. Published specs include up to 100 W per powered port (2,400 W total), 1,500 m PoF reach, 128 Gbps switching capacity, and 96 Mpps forwarding rate; VSU stacking, ERPS rings, L3 routing, and security/QoS are standard.
Product Overview
What makes PoF different. Traditional PoE+ switches push power over copper pairs; PoF centralizes power in one low-voltage, supervised location and carries it to far-edge closets through hybrid cables (fiber for data + copper conductors for DC). That means:
- Longer reach: Up to 1,500 m from the PoF switch to the indoor optical endpoint (SOE) or photoelectric AP—far beyond 100 m copper limits.
- Higher per-port power: Up to 100 W per port with an aggregate 2,400 W budget on the chassis—enough for power-hungry APs, PTZ cameras, or optical endpoints.
- Fewer field electricians: Power originates in equipment rooms; hybrid cable installation simplifies building rollouts and avoids scattered AC in ceiling spaces.
Where NS helps? Because Network-Switch delivers a custom-brand experience, you can ship NS-S5750 with your logo, faceplate color, asset labels, and day-0 software templates (VLANs, LACP on uplinks, ERPS rings, security baselines). That drastically reduces turn-up time—especially across multi-site campus projects.

Software & Management Capabilities
The NS-S5750 Switches are managed switches with the control plane you expect in modern Campus Switches:
- Segmentation & resiliency: 802.1Q VLAN (4K), QinQ, private VLAN; STP/RSTP/MSTP; ERPS (G.8032) for sub-50 ms ring recovery; LACP for active-active uplinks.
- Quality & multicast: Eight egress queues; 802.1p/DSCP classification; shaping/policing; IGMP Snooping/querier for IPTV and surveillance hygiene.
- Security: 802.1X (port/MAC), DHCP Snooping, IP Source Guard, DAI, ARP-rate-limit, CPU protection (CPP/NFPP), granular IPv4/IPv6 ACLs, BPDU guard, port security.
- Routing (Layer 3 Switches): IPv4/IPv6 static routes, RIP/RIPng, OSPFv2/v3, IS-IS, and BGP, plus policy routing—fit for routed access or compact distribution roles.
- Operations: Web UI, CLI/SSH, SNMPv1/v2c/v3, RMON, Syslog, sFlow; ZTP/CWMP (TR-069) onboarding; optics telemetry on SFP+ cages; dual-boot flash redundancy.
- Power controls (PoF/PoE management): port priority, scheduled power windows, and warm-start continuity to keep critical endpoints online during maintenance.
Because NS can preload your config (VLAN plan, ERPS ring IDs, LACP groups, AAA order, Syslog/SNMP, port roles), every closet boots with the same posture—no guesswork for contractors.
Deployment Scenarios
All-optical dorms and teaching buildings
Use NS-S5750-24SFP4XS24DP-UP at the building entry to power SOE (indoor optical) switches and APs via hybrid cable. Run 1/10G SFP+ uplinks to your aggregation or collapsed core. With 100 W per hybrid port and 2,400 W total, a single chassis can drive many floors while keeping AC centralized and supervised.
Camera-dense campuses and stadiums
PoF lets you place enclosures exactly where cameras live—on concourses or ceiling trusses—without local AC. Use ERPS rings between building entry closets for fast restoration in case of fiber nicks, and standardize your managed switches templates for IGMP and QoS so multicast storms never reach the core.
Long corridor or parking structures
Copper PoE dies at ~100 m; PoF hybrid cables carry both power and optics up to 1,500 m. Combine LACP on dual fibers for active-active headroom, and rely on dual-boot and PSU redundancy to keep lighting, cameras, and kiosks stable.
Routed access for segmented tenants
Because NS-S5750 Switches are Layer 3 switches, you can terminate VLANs per tenant, run OSPF or BGP northbound, and keep inter-VLAN policy local. This reduces trombone traffic and simplifies change windows—especially when multiple buildings share a collapsed core.

- Fan telemetry and temperature alarms for proactive maintenance; 0–45 °C operating range with altitude de-rating; compact 1RU depth for crowded racks.
- VSU virtualization lets you manage multiple building entry switches as one node; link bundling across chassis keeps traffic flowing during maintenance.
Operations, Visibility & Security
- Zero-touch day-0: We ship your standard image/config—VLAN plan (e.g., 10-User / 20-Voice / 30-Video), ERPS ring IDs, LACP on uplinks, AAA order, SNMP/Syslog endpoints, and port roles—so installers just land fiber and power.
- Troubleshooting speed: With Web/CLI/SSH, SNMP, Syslog/RMON, and sFlow, plus optics power readouts on SFP+ cages and temperature/fan alarms, you can diagnose remotely—no late-night truck rolls.
- Edge hygiene: Enable DHCP Snooping + IP Source Guard + DAI on day-0; add storm controls and ACLs at ingress; use CPP/NFPP to shield the control plane from floods.
FAQs
Q1: How far can a PoF link run?
A: Up to 1,500 m from the PoF switch to the indoor optical endpoint in the published solution design.
Q2: How much power can each hybrid port deliver?
A: Up to 100 W per port, with an aggregate 2,400 W chassis budget (24 × 100 W).
Q3: Are the uplink cages true 10G?
A: Yes, 4 × SFP+ uplinks negotiate 1G/10G; use SR/LR optics (or DAC/AOC short runs) to match your fiber plant.
Q4: Is this a “PoE switch”?
A: Functionally yes at the edge, NS-S5750 Switches supply DC over hybrid cable (PoF) to far-edge optical endpoints and APs, with scheduled power, priorities, and warm-start continuity similar to PoE+ switches management.
Q5: Can multiple chassis act as one?
A: Yes. VSU stacking/virtualization provides single-pane management and fast failover; combine with ERPS for ring protection.
