12 Fiber MPO Male to LC (UPC) OS2 Singlemode Fanout Cable

High-Density Connectivity with Premium 12 Fiber MPO to LC Singlemode Fanout Cables

Unlock seamless and high-performance connectivity in your data center or high-density cabling environment with MEFIBEROPTIC’s 12 Fiber MPO Male to LC Singlemode OS2 Fanout Cable. Also known as an MPO breakout cable or MPO harness cable, this assembly transitions a single 12-fiber MPO connection into 12 individual LC simplex connectors, enabling direct connections from high-speed transceivers (like QSFP+) to multiple lower-speed SFP+ ports or other LC-interfaced equipment.

Engineered for reliability and speed, our MPO to LC fanout cables are essential for rapid deployment in modern network infrastructures. Featuring industry-leading US Conec MPO connectors and Corning Clearcurve® singlemode fiber, these cables ensure optimal optical performance, low insertion loss, and excellent return loss, critical for maintaining signal integrity over your network links.

• Telecommunication Networks: High-density fiber distribution frames.
• Backbone Installations: Transitioning from MPO trunk cables to equipment with LC interfaces.
• High-Performance Computing (HPC): Interconnecting clusters and parallel processing systems.

Technical Specifications:

Understanding MPO Polarity (Type B – Cross-Over):

For a 12-fiber MPO connector, Type B polarity means Fiber 1 on one end connects to Fiber 12 on the other end, Fiber 2 to Fiber 11, and so on. This “flipped” configuration is crucial for establishing correct transmit/receive paths in many transceiver-to-transceiver applications.

(Optional: Include a simple diagram here if possible, showing MPO pin 1-12 mapping to LC 1-12 for Type B)

Pin 1 ---------------------------> LC 12 (Fiber 12)

Pin 2 ---------------------------> LC 11 (Fiber 11)

Pin 12 --------------------------> LC 1 (Fiber 1)

4. FAQ Section

1. Q: What is an MPO to LC fanout cable used for?

   A: It’s used to “break out” a multi-fiber MPO connection (typically 12 or 24 fibers) into individual LC connections. This is common for connecting high-speed transceivers like QSFP+ (which use MPO) to multiple SFP+ transceivers (which use LC) or to patching panels with LC ports.

2. Q: What is “Type B Polarity” and why is it important?

   A: Polarity refers to how fibers are mapped from one end of the cable to the other. Type B (Cross-Over) reverses the fiber order (e.g., fiber 1 connects to fiber 12). This is a common standard for direct connections between transceivers like QSFP+ to SFP+ to ensure the transmitter on one end correctly aligns with the receiver on the other. Always verify the polarity required by your equipment.

3. Q: What is the difference between MPO APC and LC UPC connectors?

   A: APC (Angled Physical Contact) connectors have an 8-degree angled ferrule end-face, which significantly reduces back reflection. They are typically used for singlemode applications sensitive to reflection (like CATV or long-haul). UPC (Ultra Physical Contact) connectors have a flat ferrule end-face, polished to a high standard for good contact and low reflection, common for most data center applications. Our MPO connector is APC (green housing), and the LC connectors are UPC (blue housing).

4. Q: Is this cable suitable for 40G QSFP+ to 4x 10G SFP+ connections?

   A: Yes, this 12-fiber MPO (Type B) to 12x LC fanout cable is designed for such applications. A 40G QSFP+ SR4 transceiver typically uses 8 of the 12 fibers in an MPO-12 connector (4 transmit, 4 receive). This cable allows you to connect these to four 10G SFP+ transceivers.

5. Q: What does OS2 Singlemode mean?

   A: OS2 refers to a type of singlemode fiber optimized for longer distances and higher bandwidths, commonly used with 1310nm and 1550nm wavelengths. It has stricter performance characteristics than older OS1 fiber. The Corning Clearcurve® fiber used is also bend-insensitive, reducing signal loss if the cable is bent.

6. Q: What is an LSZH jacket?

   A: LSZH stands for Low Smoke Zero Halogen. Cables with LSZH jackets emit minimal smoke and no toxic halogen compounds when exposed to fire, making them safer for use in enclosed spaces and data centers.

7. Q: Can I order this cable in different lengths or with different fanout leg lengths?

   A: Yes, while we offer standard lengths (1m, 2m, 3m, 5m, 10m), we can provide custom lengths and fanout leg configurations to meet your specific requirements. Please contact our sales team for custom orders.

5. Installation Steps (If Applicable)

MPO fanout cables require careful handling.

Basic Installation & Handling Guidelines:

1. Inspect: Before installation, carefully inspect the cable for any physical damage sustained during shipping. Ensure connectors are clean and protective dust caps are in place.
2. Observe Bend Radius: While OS2 fiber (especially bend-insensitive like Corning Clearcurve®) is robust, always respect the minimum bend radius specified for the cable (typically around 10 times the cable diameter for the main trunk and potentially less for the fanout legs) to prevent signal degradation or damage.
3. Connector Cleaning: It is CRITICAL to clean MPO and LC connector end-faces before mating using appropriate fiber optic cleaning tools (e.g., MPO cleaner, LC cleaner, fiber optic wipes, and inspection scope). Even new cables can have dust. Contamination is a primary cause of link failure.
4. MPO Connection:
   • Remove the dust cap from the MPO Male connector.
   • Align the MPO connector key with the keyway on the MPO port (e.g., on a QSFP+ transceiver or MPO adapter). The key is typically on the top side.
   • Gently push the MPO connector until it clicks into place. Do not force.
5. LC Connection:
   • Remove the dust caps from the LC simplex connectors.
   • Align each LC connector with the corresponding LC port on your SFP+ transceiver or patch panel adapter.
   • Gently push until the LC connector clicks and latches.
6. Cable Management:
   • Carefully route the fanout legs to their respective LC ports. Avoid excessive pulling, twisting, or kinking of the fanout legs.
   • Use appropriate cable management (e.g., Velcro straps, raceways) to secure the cable and fanout legs, ensuring no strain on the connectors or cable.
7. Polarity Verification: Ensure the Type B polarity of this cable matches the requirements of your specific application (e.g., QSFP+ to SFP+ breakout). Incorrect polarity will result in a non-functional link.
8. Testing (Recommended): After installation, test the links using an optical loss test set (OLTS) or by verifying connectivity through your active equipment to ensure proper signal transmission.

Disclaimer: Always follow best practices for fiber optic handling and installation. Refer to your equipment manufacturer’s guidelines for specific port connection instructions.
