SC POF fiber connectors: A connector that connects GBIC optical modules or ordinary fiber transceivers. Its shell is rectangular and the fastening method is a plug-in door type, which does not require rotation. (Mostly used on router switches)
SC POF fiber connectors：SC 250um / SC 500um / SC 750um / SC 1000um / SC 1500um / Custom made
SC POF fiber connectors is mostly used in router switches and transmission equipment side optical interfaces. SC connectors are directly plugged in and out, and are easy to use. For 100Base-FX, the connector is mostly SC type, and the core of the SC connector is inside the connector.
1. Structure and features
(1)Appearance design:
Square housing (plastic or metal), push-pull locking mechanism, plug and unplug without rotation.
Common simplex (single channel) and duplex (dual channel, used for Tx/Rx separation) types.
(2)Core components:
Ceramic/metal ferrule, customizable aperture, high-precision alignment of optical fiber, ensuring low insertion loss (typical value <0.3dB).
(3)Advantages:
High stability: plug and unplug times can reach more than 1,000 times, suitable for frequent operation scenarios.
Low loss: single-mode return loss >50dB, multi-mode >35dB, suitable for long-distance transmission.
Easy to install: push-pull design simplifies wiring, especially suitable for dense patch panel environment.
2. Typical application scenarios
Telecommunication network: used for FTTH (fiber to the home), metropolitan area network backbone connection.
Data center: early 10G/40G network, now gradually replaced by LC, but still exists in traditional equipment.
Cable TV (CATV): Due to its stability and anti-interference ability, it is used for broadcasting and television signal transmission.
Enterprise LAN: Connects switches, servers and other devices, supports Gigabit Ethernet.
3. Comparison with other connectors
| Type | Locking method | Typical application | ||
| SC | Push-pull | Telecommunications, enterprise network | ||
| LC | Snap-on | Data center, high-density equipment | ||
| FC | Thread tightening | High vibration environment (such as industrial site) | ||
| ST | Bayonet rotation | Old LAN, monitoring system |
4. Selection and use precautions
Mode selection:
Single mode (SM): yellow shell, used for long distance (up to 80km or more).
Multimode (MM): orange (OM1/OM2) or aqua (OM3/OM4), short distance (≤550m).
Anti-bending option:
Select SC connectors with "Bend Insensitive" design to reduce bending loss (such as G.657 fiber).
