SC Fiber Optical Adapter

SC Fiber Optical Adapter, its shell is rectangular, and the structural dimensions of the pin and coupling sleeve used are identical to those of the FC type,. The end face of the pin is mostly ground using PC or APC grinding methods; The fastening method adopts a plug and pull pin latch type, without the need for rotation. Equipped with metal shrapnel for easy concealed use. This type of connector has low price, convenient insertion and removal operation, small fluctuation in intervention loss, high compressive strength, and high installation density.

The plug materials of connectors include ceramic, metal, plastic, etc. Each type of connector has a different color outer frame and tail sleeve for selection. Through processes such as curing and grinding, fiber optic connectors are used to make various types of jumpers or pigtails with various types of optical cables, and are widely used in communication rooms, fiber to home, local area networks, fiber optic sensors, fiber optic communication systems, fiber optic connection transmission equipment, national defense readiness, and so on. Suitable for cable television networks, telecommunications networks, computer fiber optic networks, and optical testing equipment.

Q: Your specifications state an insertion loss of ≤0.2dB on SC Fiber Optical Adapter. Is this a typical value or a maximum value based on 100% testing? Can you provide a factory test report?

A: The ≤0.2dB mentioned in the table is a typical value. Our factory standards are more stringent, guaranteeing a maximum insertion loss of no more than 0.2dB. For bulk orders, we can provide factory test reports with random sampling or full inspection upon request. The report will include actual insertion loss and return loss test data for each adapter (or paired with patch cords), ensuring reliable and traceable performance of delivered products.

Q: How do I choose between PC, UPC, or APC SC adapters? What are the consequences of choosing the wrong one?

A: The choice mainly depends on your existing equipment and line end-face type. Simply put:

PC/UPC (Upper Physical Contact): Commonly used in digital TV and traditional telecommunications networks. UPC has higher return loss than PC.

APC (Aperture Physical Contact): Primarily used in analog transmission systems with extremely high signal reflection requirements, such as FTTH (Fiber to the Home) and CATV (Cable TV). Its green casing is a prominent identifier. Important Note: APC and UPC/PC adapters must never be used interchangeably due to their different grinding angles (8° bevel vs. flat). Using the wrong adapter will result in physical damage to the connector end face and extremely high signal attenuation. Please confirm your requirements before ordering.

Q: The SC Fiber Optical Adapter need to be plugged and unplugged frequently. How durable are they? Can they be used in outdoor cabinets?

A: Our products are designed for a mating life of over 1000 cycles, with a mating loss variation (repeatability) of ≤0.2dB during this period, meeting the requirements of high-frequency use. In terms of materials, we use engineering plastic (PBT, etc.) shells with a flame retardant rating of UL94-V0, combined with a high-temperature resistant and oxidation-resistant phosphor bronze core, allowing them to operate over a temperature range of -40°C to +75°C. Whether installed in indoor patch panels or in less demanding outdoor cabinets, they maintain stable mechanical and optical performance.

Q: I am a trader/equipment supplier, and this is my first time cooperating. Can you provide SC Fiber Optical Adapter samples for testing? What is the minimum order quantity (MOQ) and lead time?

A: Of course. We are happy to support customers in conducting performance verification before bulk purchases. For sample orders, we typically provide 1-2 pairs free of charge; you only need to cover the shipping cost, or as negotiated with us. The MOQ for standard models is very flexible, allowing for small trial orders. For standard SC adapters with ample stock, samples can be shipped the same day, and lead time for bulk orders is generally within 7-15 business days, depending on the order quantity.
