Patchcord SC/UPC – LC/UPC 50/125 Multimode OM4 Duplex Zip 2.0mm OFNR Aqua

**Patchcord SC/UPC – LC/UPC 50/125 Multimode OM4 Duplex Zip 2.0mm OFNR Aqua** from **Red Cable Technology (RCT)** is a **duplex** fiber patch cord linking **SC/UPC** on one end to **LC/UPC** on the other, built on **laser-optimized 50/125 multimode OM4** fiber inside a rugged aqua **2.0mm OFNR** duplex zip cord jacket.

**Features & Specs:**

• Shaxon’s SC/UPC – LC/UPC 50/125 OM3 patch cords feature a rugged aqua 2.0mm duplex zip cord jacket and high-quality SC and LC connectors
• Rugged aqua 2.0mm duplex zip cord OFNR jacket — aqua is the suggested jacket color for OM4; polarity clearly marked with yellow polarity labels
• SC connectors ship unclipped but include the clip to be applied in the field if desired
• SC connector: snap-in design with a 2.5mm ferrule much like the ST; simple, rugged, and low cost, with a straightforward push-on/pull-off operation that makes it a popular choice
• LC connector: small form factor (SFF) “little connector” with a 1.25mm ferrule — about half the size of SC; known for good performance and small size; made to join LC fibers where a connection or disconnection is required
• OM4 is a further improvement to OM3 using a 50µm core; it supports 10 Gigabit Ethernet at lengths up to 550 meters and 100 Gigabit Ethernet at lengths up to 150 meters
• Laser-optimized multi-mode fiber (LOMMF) is designed for use with 850 nm VCSELs

## Upgrading from Legacy OS1

When weighing on-premises versus access-network fiber replacement or a new installation, we recommend replacing legacy OS1 with a new bend-insensitive OS2 (ITU-T G.657A1) SMF cabling system to support longer reach with enhanced link performance.

## Single-Mode vs Multi-Mode on the Job

Multi-mode fiber is typically cost-effective inside buildings or corporate campuses, while single-mode is better suited to longer-distance runs. Single-mode fiber transmits over greater distances but typically requires more expensive equipment; multi-mode is the cost-effective choice for installations where lengths do not exceed a few hundred meters.

## Ultra-Long-Distance Note

For other ultra-long-distance transmissions that employ exclusively C-band and L-band with optical amplifiers, refer to the ITU-T recommendations for the most appropriate SMF types. The International Telecommunication Union (ITU) is the United Nations specialized agency for information and communication technologies – ICTs.
