Product Structure & Composition
Fiber Core and Cladding: Depending on the fiber type, for single - mode (G652D with 9/125 µm or G657A bend - insensitive fiber) the core is optimized for long - distance, low - loss transmission. Multimode fibers (OM1, OM2 with 62.5/125 µm or OM3, OM4 with 50/125 µm) are suitable for shorter - distance, higher - bandwidth applications. The cladding surrounds the core to contain the optical signal.
LC Connector: The LC connector has a small form - factor plastic body with a 1.25mm zirconia ceramic ferrule. It uses a push - pull latching mechanism for quick and secure connection. In the case of APC polish, the end - face of the ferrule is angled (usually 8°) to reduce back - reflection.
Outer Jacket: Made of PVC, LSZH, or OFNP materials. PVC is a common general - purpose jacket, LSZH is low - smoke and zero - halogen for fire - safety - conscious environments, and OFNP is plenum - rated for use in spaces where air circulation is high. The jacket provides mechanical protection to the inner fiber.

LC-LC APC Single Mode (OS2) Selection Guide
LC - LC APC and LC - LC UPC fiber patch cords are designed to meet different application requirements. The choice between them is predominantly determined by factors such as optical performance needs, cost considerations, installation environment conditions, and maintenance & handling requirements.
For applications where minimizing back - reflection is crucial, like long - distance telecommunications, high - performance data centers, and fiber - optic test and measurement equipment, LC - LC APC is the more appropriate choice.
The angled end - face of the APC connector results in an extremely high return loss. This is vital for preserving signal integrity over long distances and in high - bandwidth scenarios. For example, in a long - distance telecom link, the high return loss of LC - LC APC effectively reduces signal degradation caused by back - reflection. However, it's important to take into account the higher cost associated with the intricate APC polishing process. Also, the alignment during connection is slightly more complex due to the angled end - face. Moreover, for applications where back - reflection reduction is not a critical factor, the extra cost of LC - LC APC may not be justifiable.
For general - purpose fiber - optic connections, including certain telecommunications, data centers, and industrial applications where extreme back - reflection reduction is not the top priority, LC - LC UPC is a more suitable option.
It provides good mechanical stability with its push - pull latching mechanism and offers low insertion loss, ensuring efficient signal transmission. In a data center focused more on general connectivity and cost - effectiveness rather than ultra - low back - reflection, LC - LC 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. Nevertheless, it should be noted that in applications demanding high - bandwidth and long - distance transmission with minimal back - reflection, LC - LC UPC may not perform as well as LC - LC APC.
Parameter - Best Fit
| Parameter | Best Fit |
|---|---|
| High - bandwidth long - distance transmission with low back - reflection | LC - LC APC |
| General - purpose fiber - optic connections with cost - effectiveness | LC - LC UPC |
| High - performance data centers with strict back - reflection requirements | LC - LC APC |
| Fiber - optic test and measurement equipment | LC - LC APC |
| Applications where cost is a major constraint and back - reflection requirements are moderate | LC - LC UPC |
| High - vibration environments (both need proper securing, but APC's angled end - face may be more sensitive to misalignment) | LC - LC APC / LC - LC UPC |
| Installations in fire - safety - critical areas (both should choose appropriate jacket materials like LSZH or OFNP) | LC - LC APC / LC - LC UPC |
| Applications with frequent connection and disconnection (UPC is relatively easier to handle in terms of connector maintenance) | LC - LC UPC |
Mixed deployment guidance:
When existing LC - based equipment with UPC connectors needs to interface with new equipment that requires APC - terminated fibers, special hybrid patch cords can be utilized. In a data center with a mix of high - performance areas (such as high - speed data transmission sections) and general - purpose connection areas, LC - LC APC can be employed for the high - performance areas, while LC - LC UPC can be used for the general - purpose areas. In industrial settings, if there are high - precision measurement devices that demand low back - reflection, LC - LC APC can be used for those connections, and LC - LC UPC can be used for other general - purpose connections within the same facility to balance cost and performance.
Installation Instructions of LC-LC APC Single Mode (OS2)
Before installation, visually inspect the LC - LC APC Simplex/Duplex Single Mode (OS2) Fiber Optic Patch Cord. Check the outer jacket for any signs of damage, such as cuts, abrasions, or bulges. Examine the LC connectors to ensure the push - pull latching mechanism is in good working condition and that the ferrules are clean and free from scratches.
Clean the LC - LC APC connectors using 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 careful not to apply excessive pressure or scratch the polished surface. After wiping, use a clean, dry swab to remove any remaining moisture.
Align the key on the LC connector with the keyway in the adapter or the receiving port of the optical device. Gently insert the connector into the adapter or port until you hear a click, indicating

A5: They are ideal for FTTH, data centers, ODFs, and LAN/WAN networks.
What is the main difference between LC - LC APC and LC - LC UPC in terms of optical performance?
The main difference lies in the return loss. LC - LC 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. LC - LC UPC has a lower return loss compared to APC, although it still provides good optical performance for general - purpose applications.
How do I clean the LC - LC 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 LC - LC APC single - mode fiber patch cord?
The maximum transmission distance depends on factors such as the type of single - mode 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.
Why is the cost of the LC - LC APC patch cord higher than that of LC - LC UPC?
The cost of the LC - LC 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 LC - LC 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 LC - LC APC connectors?
When connecting LC - LC 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, making sure to seat it properly. The push - pull latching mechanism should engage smoothly, and you may need to visually inspect or use testing equipment to confirm proper alignment and connection.
