FC-FC APC Single mode fiber patch cord Selection Guide
FC - FC APC and FC - FC UPC fiber patch cables are tailored to different application needs. The decision between them is mainly influenced by factors such as back - reflection requirements, cost, and installation environment.
For applications where minimizing back - reflection is of utmost importance, such as long - distance telecommunications, high - performance data centers, and fiber - optic test and measurement equipment, FC - FC APC is the better choice.
The angled end - face of the APC connector provides an extremely high return loss, which is crucial for maintaining signal integrity over long distances and in high - bandwidth scenarios. For instance, in a long - haul telecommunications backbone network, the high return loss of FC - FC APC helps to prevent signal degradation due to back - reflection. However, the higher cost associated with the complex APC polishing process and the slightly more complex alignment during connection should be considered. Also, for applications where the reduction of back - reflection is not a critical factor, the additional cost may not be justifiable.
For general - purpose fiber - optic connections, including some telecommunications, data centers, and industrial applications where extreme back - reflection reduction is not the top priority, FC - FC UPC is a more suitable option.
It offers good mechanical stability with its threaded connector and low insertion loss, ensuring efficient signal transmission. In a data center where the focus is more on general connectivity and cost - effectiveness rather than ultra - low back - reflection, FC - FC UPC can be a cost - efficient solution. Additionally, the UPC polishing process is more common and less expensive, making it a better choice for large - scale deployments where cost is a significant factor. However, it should be noted that in applications where high - bandwidth and long - distance transmission with minimal back - reflection are required, FC - FC UPC may not perform as well as FC - FC APC.
Parameter - Best Fit
| Parameter | Best Fit |
|---|---|
| High - bandwidth long - distance transmission with low back - reflection | FC - FC APC |
| General - purpose fiber - optic connections with cost - effectiveness | FC - FC UPC |
| High - performance data centers with strict back - reflection requirements | FC - FC APC |
| Fiber - optic test and measurement equipment | FC - FC APC |
| Applications where cost is a major constraint and back - reflection requirements are moderate | FC - FC UPC |
| Environments with potential mechanical stress and vibration (both are suitable, but FC - FC APC has a slight edge in terms of overall robustness for high - performance applications) | FC - FC APC / FC - FC UPC |
| Installations where easy connection and disconnection are not a primary concern (due to the threaded connection of both types) | FC - FC APC / FC - FC UPC |
Mixed deployment guidance:
In cases where existing FC - based equipment with UPC connectors needs to interface with new equipment that requires APC - terminated fibers, special hybrid patch cords can be used. If the deployment involves a combination of high - performance areas (like high - speed data transmission sections) and general - purpose connection areas in a data center, FC - FC APC can be used for the high - performance areas, and FC - FC UPC for the general - purpose areas. In industrial settings, if there are some high - precision measurement devices that demand low back - reflection, FC - FC APC can be used for those connections, while FC - FC UPC can be used for other general - purpose connections within the same facility to balance cost and performance.

A4: Yes, each cable is 100% tested for insertion loss and return loss.
Q5: What jacket materials can I choose?
A5: PVC, LSZH, and OFNP are available for different installation environments.
What is the main difference between FC - FC APC and FC - FC UPC in terms of signal performance?
The main difference lies in the return loss. FC - FC APC has a much higher return loss due to its angled end - face, which significantly reduces back - reflection. This makes it more suitable for applications where minimizing signal reflection is crucial, such as long - distance and high - bandwidth transmission. FC - FC UPC has a lower return loss compared to APC, although it still provides good optical performance for general - purpose applications.
Can the FC - FC APC patch cord be used in a multimode network?
Typically, the FC - FC APC patch cord is designed for single - mode applications, using single - mode G652D or G657A fiber. Multimode networks require fibers with different core and cladding dimensions (e.g., 50/125 µm or 62.5/125 µm) and may use different connector polishing techniques optimized for multimode transmission. Using an FC - FC APC patch cord in a multimode network would not be ideal and may result in poor signal performance.
How do I clean the FC - FC APC connectors to maintain good performance?
Use a lint - free cleaning swab dipped in isopropyl alcohol. Gently wipe the angled end - face of the ferrule in a direction following the angle. Be very careful not to damage the angled surface. After wiping, use a clean, dry swab to remove any remaining moisture. Regular cleaning helps to maintain low insertion loss and high return loss.
What is the maximum transmission distance of the FC - FC APC single - mode fiber patch cord?
The maximum transmission distance depends on factors such as the type of fiber (G652D or G657A), the power of the optical source, and the sensitivity of the receiver. In a well - designed system, it can achieve long - distance transmission of up to 40 - 80 kilometers or more at wavelengths like 1310 nm or 1550 nm. However, in practical applications, the actual distance may be limited by other factors in the network infrastructure.
Why is the cost of the FC - FC APC patch cord higher than that of FC - FC UPC?
The cost of the FC - FC APC patch cord is higher mainly because of the more complex APC polishing process. The angled end - face of the ferrule requires precise manufacturing and polishing techniques, which are more costly compared to the UPC polishing used in FC - FC UPC. Additionally, the higher precision required for the angled end - face may lead to higher rejection rates during manufacturing, further increasing the cost.
How do I ensure proper alignment when connecting FC - FC APC connectors?
When connecting FC - FC APC connectors, first, ensure that both the angled end - faces are clean. Align the key on the connector with the keyway in the adapter. Gently insert the connector into the adapter,
