Fiber optic adapters also called fiber optical coupler, is the component to realize precise connecting between fiber opitcal connetors. It is the bridge of different fibers.
2. Fiber Optic Coupler Main Material
Fiber optic coupler's material including closure, sleeves, dust caps, metal clips.
The closure of fiber optic adapters can be plastic or metal.
For SC and LC type couplers, normally the material is plastic, and mainly using PBT material to inject. Some factories use ABS material to make it, but the hardness is poor, workers can insert the connectors from any side, this cause no optical signal on customer ONT side. Welink Technology only use PBT material to produce the couplers.
There are two types of sleeves to produce fiber optic adapters, one is bronze and another is zirconia .
Most of adapters right now are using zirconia material because of the cheap price, and some of multi mode adapters will use bronze sleeves according customer requiements.
2.3 Dust caps
Dust caps are produced by plastic, there are many types.
If devided by color, it can be transparent dust cap, blue dust cap, green dust cap.
If devided by shape, it can be normal or long type dust caps.
3. Fiber Optic adapters types
Fiber optic adapters include SC adapters, FC adapters, LC adapters, ST adapters, MU adapters, E2000 adapters, SC to FC adapters, SC to LC adapters, duplex SC adapters, ST to LC adapters, MTP adapters, or MPO adapters...
3.1 SC Type adapters
SC adapters are used to connect SC patch cord, SC pigtails or SC connectors. Thanks to the easy operation features, SC type becomes more and more popular, especailly Telefonica, Orange, O2, Bouygues operators are using this type normally.
3.2 LC Type adapters
LC adapters are used to connect LC Patch cords, LC pigtails or LC connectors.
Because it's small size featrues, LC type are using a lot in date center, fiber optical patch panel, which requires high density optical core.
3.3 FC Type adapters
FC adapters are used to connect FC patch cords, FC pigtails or FC connectors. FC type use screw to connect each other, so it's very safe, speciall used in Army or goverment important data center.
3.4 MPO type adapters
MPO adapters are used to connect MPO patch cords, MPO pigtails or MPO connectors. Because the high density features, normally it is used in data center together with LC type adapters.
4. Fiber optic adapters produce procedure
Welink Technology has our own injection factory to inject the adapter's clousure, and assemble/test in our cleaning facotries. We also can OEM with customer brand into the adapters, such as what we did for Prysmian Adapters.
Since we design, produce the adapters by ourselves, so we can OEM with any brand for you, below is the design videos.
