Descrição
The Hybrid Logic: Blue meets Green
-
SC/UPC (Blue): The “Ultra Physical Contact” end. It’s the standard for general digital data transmission and enterprise LANs where a flat, high-precision polish is sufficient.
-
SC/APC (Green): The “Angled Physical Contact” end. Featuring an 8-degree slant, it’s mandatory for CATV, GPON, and high-bit-rate systems to eliminate back-reflection.
-
SM SX (Single Mode Simplex): A single 9/125μm OS2 fiber strand that supports long-distance communication with nearly infinite bandwidth capacity.
Technical Performance Breakdown
For a reliable link, the transition between UPC and APC must be seamless. Our cables meet the following 2026 industry benchmarks:
| Especificação | SC/UPC Side | SC/APC Side | Professional Benefit |
| Connector Color | Blue | Green | Instant visual port matching |
| Perda de retorno | $\geq 50 \text{ dB}$ | $\geq 65 \text{ dB}$ | Protects source lasers from noise |
| Perda de inserção | $\leq 0,3 \text{ dB}$ | $\leq 0,3 \text{ dB}$ | Minimal light signal attenuation |
| Fiber Grade | OS2 (9/125μm) | OS2 (9/125μm) | G.652.D/G.657.A1 compliant |
| Material da jaqueta | LSZH (amarelo) | LSZH (amarelo) | Fire-safe and building-code ready |
| Ciclos de acasalamento | $>1000$ vezes | $>1000$ vezes | Durable for frequent re-patching |
Why This Jumper is Essential for Modern Networks
1. Seamless Interoperability
As ISP networks upgrade to XGS-PON or 50G-PON, the “last mile” often uses APC connectors. However, the existing backbone might still be UPC. This cable provides the direct path to connect these two worlds without replacing entire patch panels.
2. Back-Reflection Protection
By using the APC (Verde) end on your sensitive transmitter (like a CATV laser or an EDFA), you ensure that reflected light is directed out into the fiber cladding, maintaining a high return loss of $\geq 65\text{dB}$ even if the other end is a standard UPC.
3. Space-Efficient Simplex Design
For BiDi (Bi-directional) links, why use two fibers when one will do? The Simplex (SX) design reduces cable bulk in trays and is easier to manage in tight ODF (Optical Distribution Frame) cabinets.
Expert Q&A: Field Insights
Q: Can I plug the Blue end into a Green port just for a quick test?
A: Não. This is the fastest way to ruin a connection. A UPC end is flat and an APC port is angled. Plugging them together creates a physical “point contact” that can scratch both ceramic ferrules and will definitely cause an air gap with massive signal loss.
Q: Why is the return loss different on each end?
A: Return loss is a property of the connector’s polish. The 8-degree angle on the APC (Verde) end is mathematically designed to reduce reflection more effectively than the flat UPC (azul) e é por isso que ele tem uma classificação mais alta (65 dB vs. 50 dB).
P: Esse cabo é compatível com velocidades de 100G?
A: Com certeza. Os OS2 O núcleo de fibra monomodo é mais do que capaz de lidar com taxas de dados de 100G, 400G e até 800G, desde que seus transceptores e equipamentos de rede sejam classificados para essas velocidades.
P: Como faço para identificar esse cabo em um rack lotado?
A: Basta observar os conectores e os alojamentos. Uma extremidade será Blue e o outro será Green. Esse código de cores é um padrão internacional para evitar que os técnicos façam conexões incorretas.
