Extralink Single Mode SC/UPC Fiber Optic Pigtail 3m G.657.A1 900um

The Extralink Single Mode SC/UPC Fiber Optic Pigtail 3m G.657.A1 900um is a high-quality optical component designed for efficient fiber optic network splicing and termination in telecommunication infrastructures. Measuring 3 meters in length with a 900um buffer diameter, this pigtail features an SC/UPC connector and utilizes G.657.A1 single-mode fiber optimized for FTTH applications. Its construction allows for reliable signal transmission with low insertion loss, making it a dependable choice for modern optical networks.

Advantages

This fiber optic pigtail utilizes G.657.A1 single-mode fiber, which provides a significantly reduced bending radius without increasing attenuation. This characteristic is particularly beneficial during the installation of FTTx networks where optical lines frequently change direction and space within distribution boxes or customer sockets is limited. The factory-terminated SC/UPC connector ensures consistent physical contact and optical performance, saving time during on-site fusion splicing and reducing the risk of installation errors.

Suitable for

• FTTH and FTTx network installations
• Termination of single-mode optical cables in subscriber sockets
• Connection within distribution boxes and end switchgear elements
• Fusion splicing in telecommunication distribution frames

This pigtail may not be suitable for multi-mode fiber optic systems or environments requiring connectors other than SC/UPC, such as LC or APC polished ends, without appropriate adapters. It is also not intended for heavy-duty outdoor direct burial without additional protective conduit or armoring.

Key specifications

• Cable length: 3 meters
• Fiber type: Single-mode G.657.A1
• Buffer diameter: 900um
• Connector type: SC Male
• Connector polish type: UPC
• Jacket material: Polyvinyl chloride (PVC)
• Color: Yellow

To use the pigtail, strip the 900um buffer as needed to expose the bare fiber, clean the fiber according to standard optical procedures, and perform a fusion splice with the incoming distribution cable. Place the splice protector into a splice tray and route the pigtail carefully to the equipment panel or subscriber socket. Ensure the SC/UPC connector is cleaned with an appropriate optical cleaning tool before mating it to the corresponding adapter to prevent signal degradation caused by dust or oils.

What to consider before purchase

• Verify that the required connector type at the termination point is SC/UPC
• Confirm that the network infrastructure utilizes single-mode G.657.A1 fiber
• Check that the 3-meter length is sufficient for routing from the splice tray to the active equipment or socket

Handle the fiber optic pigtail with care to avoid sharp bends exceeding the minimum bending radius of the G.657.A1 fiber. Always inspect and clean optical connectors before mating to maintain optimal network performance and prevent damage to transceiver ports.
