Transition Networks 25135 8-Port 10G Unmanaged Switch
The Transition Networks 25135 is an 8-port 10G unmanaged switch engineered for distributed security and telecom infrastructure deployments. Fixed 10G connectivity across all eight ports eliminates the capex and operational overhead of managed switching—no VLAN configuration, no QoS tuning, no management interface to maintain. DIN rail mounting integrates directly into equipment racks, wall-mounted enclosures, and distributed field locations common in enterprise security networks.
Key Features
- 8 x 10G Ports: Full-duplex 10 Gigabit Ethernet on every port. Aggregate multiple camera clusters or fiber-fed access panels without bottleneck.
- Multi-Mode Fiber: 50/125µm and 62.5/125µm compatibility. Covers short to medium-distance runs (up to 2km typical); cost-effective alternative to single-mode on campus and building-to-building links.
- Unmanaged Operation: No configuration interface, no management IP, no firmware updates required. Plug in power and fiber; data flows immediately.
- DIN Rail Mount: 18" x 16" x 10" form factor fits standard DIN rail. Integrates into industrial enclosures, telecom closets, and outdoor-rated cabinets without additional mounting hardware.
- Passive Switching Fabric: No CPU bottleneck; all 8 ports operate simultaneously at full 10G line rate. Eliminates packet loss in high-throughput deployments.
- Lifetime Warranty: No recurring support costs or license renewal. Sourced direct from the manufacturer or US channel partner—factory-new, genuine product.
The 25135 is purpose-built for integrators and network architects who prioritize reliability and simplicity over granular traffic control. In security deployments, this translates to zero management overhead, lower total cost of ownership, and straightforward troubleshooting—every port is always active, always forwarding.
Multi-mode fiber infrastructure scales affordably across campus environments. A typical enterprise security network—distributed IP cameras, fiber-fed access panels, and remote NVR aggregation—benefits from the 25135's fixed 10G backbone. At 80 Gbps aggregate switching capacity, eight simultaneous camera streams (each 100-500 Mbps) are handled with headroom. The unmanaged design means no CPU-driven packet loss under sustained load, a common failure mode in undersized managed switches tasked with real-time video.
DIN rail form factor eliminates rack space debates and integrates cleanly into existing cabinet infrastructure. Whether mounted in a secure telecom closet, a distributed field cabinet, or a remote building-to-building link, the 25135 occupies minimal footprint and draws minimal power. ONVIF-compliant cameras and access-control systems stream directly to the switch with no configuration; the switch simply passes frames at wire speed to the aggregation layer or NVR.
For environments requiring VLAN isolation, traffic shaping, or SNMP monitoring, a managed switch is the correct choice. The 25135 assumes a role upstream (camera-to-core aggregation) or downstream (core-to-recorder) where raw throughput and reliability matter more than per-flow control. In those contexts—and in any deployment where configuration simplicity is a business requirement—the 25135 eliminates operational risk and cost. Lifetime warranty means no surprise renewal charges or obsolescence cliff five years out.

We spec the Transition Networks 25135 when a security infrastructure project needs 10G fiber aggregation without the headache of managed switch administration. I've installed dozens of these in campus deployments, telecom closets, and outdoor-rated cabinets where the customer's IT team explicitly wants zero configuration burden on the security side of the network. The eight fixed 10G ports and multi-mode fiber support get you straightforward point-to-point runs or small cluster aggregation—cameras to a local buffer, access panels to a nearby NVR, fiber backbone segments between buildings—all at wire speed with no CPU-driven bottleneck. The unmanaged design means there's no web GUI to forget the password to, no firmware version inconsistencies across your fleet, and no licensing renewal surprise three years in. Power it up, plug in fiber, and it works.
Technical Highlights:
- 10G Line Rate on All Ports: 80 Gbps aggregate switching capacity with no shared backplane. In real deployments, this means you can run eight simultaneous 100+ Mbps video streams without CPU-induced packet loss. Managed switches in this size class often throttle performance when CPU is taxed; the 25135 has no CPU to tax.
- Multi-Mode Fiber (50/125µm / 62.5/125µm): 2km typical range covers building-to-building links and campus sprawl without requiring expensive single-mode infrastructure. For security integrators, this is the sweet spot—far enough for distributed architecture, cheap enough to deploy across a 10-site region.
- Passive Switching Fabric: No management overhead, no configuration state to corrupt, no firmware bug to patch. If a port fails, seven others keep working. Reliability is the feature.
- DIN Rail Form Factor: 18" x 16" x 10" fits standard industrial enclosures and telecom racks. Mounts flat on a rail, leaving room for patch panels and terminal blocks without spatial compromise.
- Lifetime Warranty: No renewal, no licensing gates, no per-port fees. Total cost of ownership calculation is clean: buy it once, install it, forget about it for the life of the network.
Deployment Considerations:
- Multi-mode fiber range is 2km typical for 10G; beyond that, single-mode fiber and a managed (more expensive) switch become necessary. Know your longest span before specifying.
- Unmanaged means no traffic isolation between security cameras and other network services if you share the same switch. If you need VLAN segmentation (e.g., cameras isolated from corporate data), use a managed core switch and the 25135 as a leaf-layer aggregator only.
- No SNMP, no syslog, no way to remotely verify port status or detect cable faults. Pairs well with optical power meters and visual inspection; keep a multimeter and fiber-optic tester in your van.
- DIN rail mounting requires a standard-depth enclosure; confirm your cabinet depth before ordering. 18" depth is typical for telecom gear; older 12" racks may be tight.
- Power supply is external (check datasheet for voltage/wattage); ensure your cabinet PDU has a spare outlet and the correct connector type. Field replacement is straightforward, but plan logistics.
The 25135 is purpose-built for integrators and network engineers who prioritize uptime and simplicity over granular control. If your project calls for straightforward fiber aggregation, no management overhead, and lifetime reliability, the Transition Networks catalog offers this and complementary products for larger campus deployments.
