About Us
A PoE switch factory, not a trading company
90 PoE models built on our own line since 2011 — switches, injectors, splitters and extenders, with SFP uplinks on 13 of them.
Who we are
SFP PoE Switch Factory is the PoE business of SFP PoE Switch Factory, a manufacturer that has been building surveillance transmission equipment since 2011. The product line we focus on is narrow on purpose: everything that carries data and power down the same copper pair — PoE switches, injectors, splitters and extenders.
The reason for the focus is practical. PoE failures are rarely mysterious. A switch is specified with the wrong budget, an injector is dropped into a gigabit link because nobody read the speed row, a splitter outputs 12 V into a device that wanted 24 V, or an extender chain is two hops too long for the budget left at the far end. Every one of those is a specification question, and specification is where a factory can be useful rather than just quoting a price.
So the site is built the same way: 90 models with the specifications transcribed from our current product data, checked against the model photographs, and written up with the arithmetic that decides whether a given combination will actually work on site. If a model in this range does not fit a project, we say so and point at the one that does.
Customers are distributors, system integrators, installers and brand owners — mostly people who resell into CCTV and network projects and need a factory that answers a technical question in a day rather than a marketplace seller that forwards it.
What we manufacture
Four families that make up one power chain. Most projects need two or three of them together, which is why they are specified as a set rather than picked one at a time.
PoE Switches
Powered edge switching from 4 to 24 ports, 100M and gigabit, copper and SFP uplinks, 30–400 W supplies.
See modelsPoE Extenders
Standard and waterproof repeaters that rebuild data and power, single units or cascaded chains.
See modelsPoE Splitters
48 V PoE in, fixed DC out at 5/9/12/24 V, standard and non-standard pinouts, waterproof housings.
See modelsPoE Injectors
Single and multi-port injectors from 30 W to 90 W, for retrofits where the switch has no PoE.
See modelsInside our plant
Production runs on SMT lines, so the boards inside a switch, injector or splitter are built and populated in-house rather than assembled from bought-in modules. That matters most when a distributor needs a variant — a different port count, a different pinout, a different connector — because the change happens at the design and build stage rather than at a repackaging table.
The other facility worth naming is the 120 kV simulated lightning impulse test platform. PoE equipment ends up on poles, on roofs and at the end of long outdoor cable runs, which is exactly where surge energy arrives. Having the impulse bench on site means the protective design can be developed and re-checked against the same test setup, instead of being described on a datasheet and hoped for in the field.
- SMT production — boards populated on our own lines, not outsourced
- 120 kV impulse bench — surge testing on site, at product level
- OEM / ODM — branding, packaging and model numbering on the same hardware (what a private-label run changes)
- Documentation — datasheets and the product guide maintained as the range changes
Three projects we quote most often
Same range, three different constraint.
How an OEM order runs
Six steps, the same for a first sample order and a repeat run. Each one ends with something written down, so nothing about the variant depends on what somebody remembers.
- 1
You send the project
Device count, the class printed on the device label, the longest cable run, and whether the uplink back to the core is copper or fibre. Branding and packaging needs go in the same message.
An answer from an engineer, not a price list.
- 2
We work the numbers
The model is chosen from the budget arithmetic with a 20% reserve kept back, not from the headline port count. If the run needs an extender or a splitter, that goes in the same reply.
The model, and the arithmetic behind it.
- 3
Sample from current production
The sample is the hardware that will be in the run, not a hand-built unit. Your label goes on it if the artwork is ready, so the sample shows what your customer will unpack.
One or two units to test on site, plus the current datasheet.
- 4
The variant is locked in writing
Model number, label artwork, packaging, pinout and default settings are confirmed before anything goes on the line. This is the point where a change stops being a message and becomes a new order.
A specification you can forward to your own customer.
- 5
Run, check, pack
Boards are populated on the SMT line, assembled, and checked against the specification agreed in step 4, then packed to that same specification.
Units packed the way step 4 describes, not the way the last order was packed.
- 6
Documents and shipping
Datasheet, packing list and export paperwork, shipped from our plant through your forwarder or ours.
Paperwork that matches what was actually loaded.
MOQ, pricing and lead time depend on the model, the variant and the quantity, so they are quoted for a specific project rather than published as a number that would not apply to yours.

Production
Factory visits by appointment — tell us which families you want to see on the line. If a visit is not practical before the first order, ask for a walkthrough on a video call instead: we put the SMT line and the impulse bench on screen with the project open beside it.
Questions buyers ask us
Are you a factory or a trading company?
We manufacture. The production line, SMT equipment and the 120 kV simulated lightning impulse test platform are ours, in our own plant; enquiries are answered by our export office. Model numbers, branding and packaging are built to order for distributors, integrators and brand owners.
Which PoE standards do your switches support?
Models in the current range cover IEEE 802.3af, 802.3at and 802.3bt, with power supplies from 30 W to 400 W. Non-standard passive models at fixed voltages also exist for legacy installations — they are labelled as such, and must not be mixed with standard PSEs on the same segment.
Do the switches have SFP uplinks?
Yes. 13 of the 20 switch models carry SFP uplink cages alongside copper uplinks, which lets a floor switch reach the core over fibre without a media converter and without changing the PoE budget on the powered ports.
Can you supply under our own brand?
Yes — OEM and private-label production runs on the same hardware: your logo, your packaging, your model numbering and your documentation. Send the specification and target market; we come back with the closest platform and the changes needed to match it.
How do I get pricing and a datasheet?
Send the model list, the camera count and the cable length to sales@sfppoeswitchfactory.com. We reply with the current datasheet, the power budget check for your site, and a quotation. Enquiries reach a real engineer, not a form queue.
Send the project, not the product name
Camera count, PoE class and cable run length are enough for us to come back with a working combination.
