HIGH DENSITY DATA CENTER
CABLING GUIDE
PROVIDING MTP CABLING SOLUTIONS FOR THE SMART DATA CENTER.
APPROVED NETWORKS SETS THE STANDARDThe industry authority on fiber optic connectivity, Approved Networks has been consistently delivering first-to-market compatibility solutions for over a decade, even in the most rigorous, optical networking environments. Headquartered in Los Angeles, Approved currently provides technical, logistical and sales support to over 3,000 clients in 30 countries.
KEEPING PACE WITH GROWTH - THE SHIFT TO 40GB AND BEYONDConstant demand for more speed and bandwidth within the switch and server environments means data centers must keep evolving. The shift to 40/100G can be costly and choosing the correct fiber, polarity, connector and management system can be daunting. When it comes to infrastructure, a clear migration plan has become a necessity and, in many verticals, a matter of survival. Use this informational guide from Approved to gain a fundamental understanding of the cabling, connections and systems needed to achieve success in today’s data centers.
CABLING BASICSApproved jumpers come in many different varieties. These drawings show the basic difference between two of the most commonly used cables.
DUPLEX VS MULTIPLE STRAND FIBER40/100GB optics means higher density connectivity in the switch. The added connectivity, however, can create congestion in your cabling. This cross-section comparison of the Duplex, 12 and 24 fiber cabling shows the spec savings achieved when using multi-strand fiber.
DUPLEX
12 FIBER
24 FIBER
DUPLEX FIBER
The familiar duplex fiber standard in all data center facilities, the 1/10GB jumper, comes in 50/125um multimode (OM2, OM3, OM4, OM4+) and 9/125um singlemode. It has 4 flame ratings and is available in over 10 connectors, including LC, Uniboot, and SC. These cables can operate at speeds of over 100Gps (Think QSFP28-LR4 – Single mode.) They’re perfect for legacy applications as well as high speed, high bandwidth environments.
MULTI-STRAND MTP FIBER
Migration to multiple-strand fiber (Think 40Gbps and 100Gbps.) employs parallel optic technology. Multi-strand jumpers use MTP connectors for both 12-fiber (40/100G) and 24-fiber (100G). They come in standard, laser optimized 50/125um multimode (OM3, OM4, OM4+) and 9/125um singlemode. Male and female connectors vary with 8, 12, 20, and 24 fiber configurations.
• 2 strands of glass• Typically found in a “zipcord” construction• Most often used between devices where a separate transmit and receive are required• Available in multimode 50/125um (OM2, OM3, OM4, OM4+) and singlemode 9/125um
• 12 strands of glass • Commonly used in 40G applications with high-density components• Reduces space requirements by over 50%• Available in multimode, laser optimized 50/125um (OM3, OM4, OM4+) and singlemode 9/25um NOTE: *40/100G QSFP optics use 8 of the 12 fibers in the cable
• 24 strands of glass• Commonly used in 100G applications with high-density components• Reduces space requirements by over 75%• Available in multimode, laser optimized 50/125um (OM3, OM4, OM4+) and singlemode 9/25um NOTE: *100G CFP use 20 of the 24 fibers in the cable

KEY-UP | KEY-DOWN
MALE | FEMALE
Approved uses only US Conec MTP® connectors, which are high-performance MPO connectors engineered to improve optical and mechanical performance. MTP connectors are in compliance with all MPO standards, including EIA/TIA-604-5, FOCIS 5 and IEC-61754-7. They connect with all generic, compliant MPO-style connectors.
12 AND 24 FIBER CONNECTORS
• 12 fiber, single, in-line connector (shown left). Pins 1 - 6 are for Transmit (TX) and 7 - 12 are for Receive (RX).• 24 fiber, dual, in-line connector (shown left). Pins 13 - 24 are for Transmit (TX) and 1 - 12 are for Receive (RX).
PARALLEL OPTICS - 40GB (QSFP+) AND 100GB (QSFP28/CFP) CONNECTORS
40GB and 100GB Ethernet employ parallel optics. That means data is transmitted and received simultaneously on MTP interfaces through 10/25GB simplex transmission over each individual strand in the cable. Transmission methodology is determined by current IEEE channel/lane assignments for active equipment interfaces.
KEY = TX = RX = NOT USED
MTP MULTIPLE STRAND CONNECTORS AND FIBER POLARITYUnderstanding 40/100GB connections and how they transmit through your network infrastructure is key to a successful migration. Polarity and fiber usage is more complex than it is with traditional cabling. Understanding basic connection and pinouts as described here will minimize potential for error.
POLARITY TYPES Polarity types A, B, C and Universal are available in 12 and 24 fiber options.Fiber optics rely on bi-directional transmissions where the transmitter port (TX) on one end connects to the receiver port (RX) on the other. Since fiber optic links require this two-way (duplex) connection, there is potential for error by connecting a TX to TX or RX to RX. Connectivity methods (A, B, C & Universal) now exist to help ensure easier, proper channel alignment during planning and installation.
40/100GB 8-FIBER QSFPPins 1-4 = Transmit (TX)Pins 9-12 = Receive (RX)Pins 5-8 = not used

* NOTES: OM4+ extends above configuration distances to 600 meters at 10Gps. OM5 is designed to support at least four low-cost wavelengths in the 850-950 nm range, enabling optimal support of emerging Shortwave Wavelength Division Multiplexing (SWDM) applications that reduce parallel fiber count by at least a factor of four to allow continued use of just two fibers (rather than eight) for transmitting 40 Gb/s and 100 Gb/s and reduced fiber counts for higher speeds.
