Product Structure & Composition
Fiber Core and Cladding: For single - mode, G652D fiber has a 9/125 µm core - cladding structure optimized for long - distance, low - loss transmission, while G657A offers bend - insensitive properties. Multimode fibers, such as OM1/OM2 with 62.5/125 µm and OM3/OM4 with 50/125 µm, are suitable for shorter - distance, higher - bandwidth applications. The cladding surrounds the core to keep the optical signal contained.
SC Connector: The SC connector has a rectangular plastic body and a 2.5mm zirconia ceramic ferrule. In the case of APC polish, the end - face of the ferrule is angled (usually 8°) to minimize back - reflection. The push - pull locking mechanism of the SC connector provides a quick and secure connection.
Outer Jacket: Made of flame - retardant PVC, LSZH, or OFNP materials. PVC is a common, cost - effective option for general - purpose use. LSZH is ideal for environments where fire - safety is a concern as it emits less smoke and no halogen - containing toxic gases when burned. OFNP is designed for plenum spaces where air circulation is high, ensuring fire - retardant performance. The jacket protects the inner fiber from mechanical damage.

SC-SC APC Single mode Fiber Patch Cords Selection Guide
When choosing between an SC - SC APC and SC - SC UPC fiber patch cord
If your application involves long - distance signal transmission, high - performance data centers, or fiber - optic test and measurement where minimizing back - reflection is of utmost importance, the SC - SC APC is the better choice.
The angled end - face of the APC connector provides an extremely high return loss, which is essential for maintaining signal integrity over long distances and in high - bandwidth scenarios. For instance, in a long - haul telecom link, the high return loss of SC - SC APC helps prevent signal degradation caused by back - reflection. However, it's important to note that the APC polishing process is more complex, resulting in a higher manufacturing cost. Also, the alignment during connection is slightly more challenging due to the angled end - face. For applications where back - reflection reduction is not a critical factor, the additional cost of the SC - SC APC may not be justifiable.
For general - purpose fiber - optic connections, such as those in LANs, some data center connections, or applications where extreme back - reflection reduction is not the top priority, the SC - SC UPC is a more suitable option. It offers good mechanical stability with its push - pull locking mechanism and low insertion loss, ensuring efficient signal transmission. The UPC polishing process is more common and less expensive, making it a cost - effective choice for large - scale deployments. However, in applications that demand high - bandwidth and long - distance transmission with minimal back - reflection, the SC - SC UPC may not perform as well as the SC - SC APC.
Parameter - Best Fit
| Parameter | Best Fit |
|---|---|
| High - bandwidth long - distance transmission with low back - reflection | SC - SC APC |
| General - purpose fiber - optic connections with cost - effectiveness | SC - SC UPC |
| High - performance data centers with strict back - reflection requirements | SC - SC APC |
| Fiber - optic test and measurement equipment | SC - SC APC |
| Applications where cost is a major constraint and back - reflection requirements are moderate | SC - SC UPC |
| High - vibration environments (both need proper securing, but APC's angled end - face may be more sensitive to misalignment) | SC - SC APC / SC - SC UPC |
| Installations in fire - safety - critical areas (both should choose appropriate jacket materials like LSZH or OFNP) | SC - SC APC / SC - SC UPC |
| Applications with frequent connection and disconnection (UPC is relatively easier to handle in terms of connector maintenance) | SC - SC UPC |
Mixed deployment guidance:
In cases where existing SC - 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, SC - SC APC can be used for the high - performance areas, and SC - SC UPC for the general - purpose areas. In industrial settings, if there are some high - precision measurement devices that demand low back - reflection, SC - SC APC can be used for those connections, while SC - SC UPC can be used for other general - purpose connections within the same facility to balance cost and performance.
Installation Instructions of SC-SC APC fiber patch cord
Pre - installation Inspection : Visually check the SC - SC APC fiber patch cord. Ensure the outer jacket has no cuts, abrasions, or bulges. Examine the SC connectors; the push - pull locking mechanism should be in good condition, and the ferrules should be clean and free from scratches.
Connector Cleaning: Use a lint - free cleaning swab dipped in isopropyl alcohol. Gently wipe the angled end - face of the APC ferrule in a direction following the angle. Be careful not to apply excessive pressure. After wiping, use a clean, dry swab to remove any remaining moisture.
Connection : Align the key on the SC connector with the keyway in the adapter or the receiving port of the optical device. Gently insert the connector and push until you feel a secure lock, indicating proper connection.
Cable Routing and Management : Route the patch cord while maintaining the minimum bending radius. For single - mode fibers, it's typically around 10 times the cable diameter. Use cable ties or trays to secure the cord in place for better cable management.
Post - installation Testing : After installation, use an optical power meter to measure the insertion loss. Compare the measured value with the specified value. If it's significantly higher, re - check the connection, clean the connectors if necessary, and inspect the cable for damage.
