1×2 Plc Fiber Splitter - Without Connector

A: Great question! For a 1×2 split, you could technically go with either PLC or FBT – both work. But here's the thing: if you're planning to scale up later or need rock-solid wavelength consistency across 1260-1650nm, PLC is the way to go. FBT splitters can have slight wavelength-dependent loss variations, while our PLC splitters deliver uniform performance whether you're running 1310nm, 1490nm, or 1550nm signals. Plus, PLC handles temperature swings (-40°C to +85°C) like a champ – we've had customers deploy these in outdoor cabinets from Scandinavia to the Middle East without issues.

A: Exactly right – this is a bare fiber version, which gives you maximum flexibility. You'll get the splitter with 900μm or 250μm bare fiber ends that you can either fusion splice directly into your network or terminate with your preferred connectors (SC, LC, FC, whatever your setup needs). A lot of our customers prefer this for permanent installations where they're splicing into existing infrastructure. If you'd rather have a plug-and-play solution, we offer pre-connectorized versions too – just let us know your connector type and fiber length requirements.

A: For a 1×2 split, you're looking at roughly 3.4-3.8dB insertion loss per output port – that's the theoretical 3dB split loss plus a small amount of excess loss from the chip itself. Our splitters typically come in at the lower end of that range. Keep in mind this is significantly better than daisy-chaining multiple couplers. The uniformity between the two output ports is within ±0.6dB, so your downstream equipment sees balanced signals. For your link budget calculations, I'd recommend using 4dB as a safe planning number.

A: Absolutely – PLC splitters are fully passive and work in both directions. You can use it as a 1×2 splitter (one input, two outputs) or flip it around as a 2×1 combiner (two inputs, one output). This makes them perfect for PON applications where you've got downstream broadcast signals and upstream data from ONTs sharing the same fiber. Just remember that in combiner mode, you'll still see that ~3.5dB loss from each input to the output – physics doesn't change!

A: Think of it this way: the mini module (what this product uses) is compact and great for space-constrained installations like splice trays, distribution boxes, or rack-mount panels. It's got a small footprint and the fiber pigtails come out neatly from one end. Steel tube packaging, on the other hand, wraps the PLC chip in a stainless steel tube – it's more rugged and better suited for harsh environments or when you need extra mechanical protection. For most indoor FTTH and enterprise applications, the mini module is the go-to choice. We typically recommend steel tube for outdoor cabinets or industrial settings.

A: Simple field test: use an optical power meter. Inject a known power level (say, 0dBm at 1310nm or 1550nm) into the input port, then measure each output. You should see roughly equal power on both outputs, around -3.5 to -4dB from your input. If one port shows significantly higher loss or no signal, check your splice points first – 9 times out of 10, it's a fusion splice issue, not the splitter. We 100% test every unit before shipping with insertion loss, uniformity, and return loss measurements, so if you're seeing problems right out of the box, reach out to us with your test results and we'll sort it out.
