SC/APC Fiber Fast Connector Selection Guide
Choose the SC/APC Fast Connector when:
Deploying FTTH/FTTx networks where signal integrity is critical. The angled 8° polish significantly reduces back-reflection (return loss ≥50dB), which is essential for PON (Passive Optical Network) uplinks and RF-over-fiber applications like CATV.
Working with analog or sensitive video transmission systems, as the superior return loss minimizes signal degradation caused by reflected light.
Operating in standard telecom rooms or ODN (Optical Distribution Network) environments where the larger SC connector's push-pull mechanism provides durability and consistent alignment.
Needing field termination without epoxy or polishing. The pre-polished ferrule and mechanical splice technology allow for quick, reliable terminations in the field.
Choose the SC/UPC Fast Connector when:
The application is standard digital communication (e.g., LAN, CCTV, general data links) where high return loss is not a primary requirement.
Budget is a primary constraint. SC/UPC connectors are generally more cost-effective than their APC counterparts while still offering low insertion loss.
The network does not require analog or PON uplink performance. For standard point-to-point digital links, UPC polishing provides adequate performance.
Choose the LC/APC Fast Connector when:
Space is at a premium. The LC connector's 1.25mm ferrule occupies half the space of an SC connector, making it ideal for high-density patch panels and data centers.
High-speed transmission (10G/40G/100G) and high performance are required, especially in single-mode networks where low back-reflection is critical.
Deploying modern FTTH networks in space-constrained environments like MDUs (Multi-Dwelling Units) or small telecom cabinets.
Note: Green connectors indicate APC, and blue indicates UPC. Never mix APC and UPC connectors in a link, as this will cause high insertion loss and damage the ferrule end-faces.

Installation Instructions
Check – Make sure the housing has no cracks, the APC end face is clean and scratch-free, and the pre-installed fiber has no bends or cuts.
Fiber Preparation – Strip the jacket to expose 125~900μm of the fiber core, then wipe it clean with a non-woven cloth and cleaner.
Connector Installation – Align the prepared fiber with the pre-installed fiber, push it in along the SC push-pull mechanism until it locks.
Testing – Measure insertion loss ≤0.3dB, overall return loss ≥40dB, APC end ≥60dB; if it exceeds limits, recheck alignment, connection, or the APC end face.

Frequently Asked Questions & Quick Inquiry
SC/APC Fiber Fast Connector FAQ
Why is the 8° APC polish important for minimizing back - reflection?
The 8° angled surface of the APC polish causes the reflected light to be redirected at an angle, reducing the amount of light that is reflected back towards the source. In a standard flat - polished connector, a significant portion of the light can be reflected straight back, causing interference. The angled surface of the APC polish scatters the reflected light, resulting in a much higher return loss, typically RL ≥ 60dB in this case, which effectively minimizes back - reflection and improves signal quality.
Can the SC/APC fiber fast connector be used in outdoor applications?
Yes, it can be used in outdoor applications. It has been tested for temperature cycling (operating temperature from -40 to +85°;C), vibration, and environmental adaptability. These tests ensure that it can withstand the harsh environmental conditions often associated with outdoor use, such as temperature variations, wind - induced vibrations, and exposure to moisture. However, it may be necessary to use appropriate protective enclosures or coatings depending on the specific outdoor environment.
What is the advantage of pre - embedded fiber in the connector?
The pre - embedded fiber simplifies the on - site termination process. Instead of having to carefully insert and align the fiber during installation, which can be a complex and time - consuming task, especially in the field, the pre - embedded fiber is already in place. This reduces the installation time significantly and also reduces the risk of installation errors, as there is less room for misalignment. It allows for a more efficient and reliable installation, even by installers with limited experience in fiber optic termination.
