There are many types of adapter fiber optical, and end users can freely choose according to the number of fiber cores, interface type, transmission mode, performance indicators and application scenarios. They are mainly used in fiber optical distribution frames, fiber optic communication network equipment, fiber optic broadband access, fiber optic CATA, fiber optic instrumentation and other equipment, and have good compatibility and transmission stability.
Adapter Fiber Interface
Yingda can offer below optical interfaces for adapter fiber, both sides with the same type of interface for the same fiber connectors docking or different interface for different fiber connectors docking.
- SC type connector: Square plug-in connector (2.5mm sleeve), suitable for router and switch ports, requiring a lightweight plastic housing.
- LC type connector: Small square connector (1.25mm sleeve), suitable for high-density cabling (such as SFP modules).
- FC type connector: Metal threaded locking connector (2.5mm sleeve), highly shockproof, specifically designed for telecommunications equipment rooms.
- ST type connector: Bayonet-type rotating lock connector (2.5mm sleeve), commonly deployed in fiber optic patch panels.
- MPO/MTP type: Multi-core high-speed connection, the preferred choice for 40G/100G networks in data centers.
Hybrid adapters solve compatibility issues, such as adapter fiber LC SC, LC ST, LC FC, SC ST, SC FC, ST SC, ST FC, DIN FC, DIN SC, E2000 LC, E2000 FC, E2000 SC, MTRJ LC, adapter duplex or simplex, all can connect devices with different connectors.
Adapter Fiber Mode & Endface Polishing Method
Though the standard adapter fiber itself not have fiber inside, so the fiber mode and endface polishing method doesn’t matter, but the hybrid adapter with different interface have built-in fibers inside. In order to make the whole fiber optic system looks uniform, there are international standard colors to distinguish them:
Adapter Fiber Core Performance
Yingda adopt Grade A ceramic sleeve, tension 2~6N, which ensures end face alignment accuracy and attenuation ≤0.2dB. And for adapter fiber LC MU require a 1.25mm sleeve, while adapter FC SC ST require a 2.5mm sleeve.
Adapter Fiber Housing Materials
Yingda FC ST adapter fiber use metal housings, resistant to interference, and LC SC adapter fiber use plastic housing with light weight, both type use V class flame retardant materials and have passed dual 85°C (high and low temperature) aging tests.
How to Choose Adapter Fiber?
Yingda make a brief introduction of how to choose adapter fiber based on our experience and applications, hope it can help you more.
