DESCRIPTION
The LC UPC to SC UPC Single Mode Duplex 2.0mm Fiber Patch Cable is designed for reliable, low-loss connectivity in telecom, FTTH, enterprise, and data center environments. Built with OS2 9/125µm single mode fiber, it ensures long-distance transmission with stable UPC (Ultra Physical Contact) polished connectors. The duplex design supports simultaneous two-way communication, while the φ2.0mm jacket balances durability with flexibility for efficient routing and installation.

- Flexible Options:Simplex or Duplex version and Fan-out on request. Any other connector type at another side upon request.
- Stable UPC Polish Connectors:UPC connectors ensure precise core alignment and reduce insertion loss, suitable for high-performance networks.
- Long-distance Performance:OS2 single mode fiber supports long-haul communication, ensuring low attenuation at standard telecom wavelengths.
- Flexible φ2.0mm Design:Compact 2.0mm jacket allows easier routing in cable trays, racks, and tight installation spaces.
- High Compliance:Manufactured under IEC and TIA/EIA standards, ensuring global compatibility and reliability.

- What is the difference between UPC and APC connectors?
UPC has a flat polish with ≤ -50 dB return loss, while APC is angled with ≤ -60 dB, used when reflection sensitivity is critical.
- What is the advantage of duplex over simplex?
Duplex cables support two-way transmission, ideal for most telecom and enterprise applications.
- Can I choose jacket materials?
Yes, standard PVC and LSZH (low-smoke, halogen-free) are available for different installation needs.
- What lengths are available?
Custom lengths from 0.5 m up to 100 m or more can be provided.
- Is this patch cable bend-resistant?
Standard versions are not bend-insensitive, but G.657A2 bend-insensitive fiber can be customized.
- Can it be used outdoors?
This version is indoor-rated; armored or outdoor waterproof designs are available on request.
- What return loss can be expected with UPC connectors?
UPC connectors typically achieve ≥ 50 dB return loss.
- Is this cable compatible with existing LC and SC adapters?
Yes, it is fully compliant with standard LC and SC adapter interfaces.
