Single-mode fiber optic patch cord SM SC/APC-SC/APC simplex 3.0 mm LSZH G657B3 20m white FO-SASA-SS31-0200-WH

Single-mode fiber optic SC/APC – reliability and transmission efficiency

This fiber optic patch cord, made of single-mode (SM) fiber and terminated with SC/APC connectors, is an ideal solution for demanding networks where stability and high throughput are key. The 20-meter cable provides flexibility in network configuration, and its design is intended to minimize signal loss.

The patch cord utilizes G657B3 fiber, which is characterized by low attenuation and high bend resistance. This makes it particularly useful in installations where the cable must be routed in tight spaces or subjected to frequent bends. APC (Angled Physical Contact) polished connectors minimize signal reflections, resulting in improved data transmission quality.

Construction and application

The cable has a diameter of 3.0 mm and is made of LSZH (Low Smoke Zero Halogen) jacket, which limits the emission of toxic substances in the event of a fire. Simplex construction means a single optical fiber inside the cable, simplifying installation and cable management. The minimum bending radius of 5 mm allows for flexible cable routing without the risk of fiber damage.

This patch cord finds application in a wide range of telecommunications and data networks, such as:

• LAN/WAN networks
• Data centers
• Monitoring systems
• Television signal transmission
• Connections of active devices (switches, routers, media converters)

Parameters and benefits

Insertion loss below 0.20 dB and return loss above 60 dB guarantee high signal quality and minimize losses during data transmission. A wide operating temperature range from -40°C to 85°C allows the cable to be used in various environmental conditions. The white color makes it easier to identify the cable in the installation. The use of G657B3 fiber ensures compatibility with modern network standards and ease of installation thanks to its flexibility. The LSZH jacket increases safety by limiting the emission of harmful substances in the event of a fire – important for both installers and end users.
