SC Fiber Pigtail

SC Fiber Pigtail refers to a connector similar to a half jumper used to connect fiber optic and fiber optic couplers, which includes a jumper connector and a section of fiber optic.

It belongs to tight-buffered fiber, meaning that a 0.9mm coating layer (usually PVC or LSZH material) is directly and tightly wrapped around the bare fiber. It is mainly used for intermediate splicing in fiber optic patch cords, internal splicing in optical distribution boxes (ODFs), or direct connection to the interface of optical modules/equipment. Because it is thin and flexible, it is suitable for routing in high-density environments and easily fits into small protective sleeves.

Why must we use 0.9mm yellow SC Fiber Pigtail? What's the difference between them and 2.0mm or 3.0mm SC Fiber Pigtail?

The main differences between these three specifications lie in their application scenarios and structures:

0.9mm Tight-buffered Pigtail (Yellow):

Structure: It belongs to tight-buffered fiber, meaning that a 0.9mm coating layer (usually PVC or LSZH material) is directly and tightly wrapped around the bare fiber.

Applications: Primarily used for intermediate splicing in fiber optic patch cords, internal splicing in optical distribution boxes (ODFs), or direct access to the interface of optical modules/equipment. Because it is thin and flexible, it is suitable for cabling in high-density environments and is easy to insert into small protective sleeves.

Why yellow? This is specified by the industry standard (TIA-598C), where yellow represents single-mode fiber (distinguished from orange multimode fiber), making it easy for construction and maintenance personnel to quickly identify.

2.0mm/3.0mm Pigtail (usually for patch cords):

Structure: A layer of Kevlar (aramid yarn) and an outer sheath are wrapped around the 0.9mm tight-buffered fiber. This makes them very robust and have high tensile strength.

Applications: Used directly as patch cords between devices, connecting switches, routers, etc., and needs to withstand daily pulling and bending.

Summary: If you are using it for fusion splicing or high-density cabling inside a server chassis, 0.9mm is the correct choice; if it is used for connecting external devices, 2.0mm or 3.0mm patch cords with plugs may be more suitable.

What is the typical insertion loss of SC 0.9mm yellow SC Fiber Pigtail? Can it be guaranteed to pass 100% of the tests?

Regarding insertion loss, we manufacture and test according to telecom-grade standards, specifically as follows:

Standard Value: International standards typically require single-mode connectors to have an insertion loss ≤ 0.3dB. Our factory's internal shipping standards are even stricter, controlling it to ≤ 0.2dB.

Factory Testing: Yes, we guarantee 100% passing of all inspections.

Each pigtail undergoes interferometry testing after grinding and assembly to check its end-face curvature radius, core height, and other three-dimensional parameters.

Simultaneously, it passes 100% of the insertion loss and return loss tests (light source and optical power meter). Only those that pass the tests are labeled with a certificate of conformity and packaged.

If needed, we can provide the batch's factory test report.

Conformity: We use high-precision Japanese or imported grinding equipment to ensure consistency within a batch, avoiding situations where "the first one is good, the hundredth one is bad."

Can the length and packaging of this 0.9mm SC Fiber Pigtail be customized? (e.g., private labeling, individual packaging)

Absolutely. We support a variety of flexible customization services to meet your project needs:

Custom Length:

Besides the standard 1m and 1.5m lengths, we can customize any length according to your requirements, such as 0.5m, 2m, 3m, and even non-integer lengths. However, please note that customized lengths usually have a minimum order quantity (MOQ).

Terminal Type:

In addition to the most common SC/UPC, we can also produce SC/APC (green ferrule, for TV signals or high-precision transmission), as well as 0.9mm pigtails with other interface types such as FC, LC, and ST.

Packaging and Labeling (OEM):

Bulk: Suitable for large-volume projects, lowest cost.

Individual Packaging: Each pigtail is individually packaged in a dustproof plastic bag to prevent scratches and dirt, suitable for distribution or projects with high cleanliness requirements.

Labeling Service: We can label each pigtail with a specified number (e.g., A1-B2) according to your provided list. This is crucial for splicing projects in large data centers, greatly improving construction efficiency.

Outer carton label: Your company logo and specifications can be printed on it.
