2 PROVIDING MTP CABLING SOLUTIONS FOR THE SMART DATA CENTER. APPROVED NETWORKS SETS THE STANDARD The 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 BEYOND Constant 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 BASICS Approved jumpers come in many different varieties. These drawings show the basic difference between two of the most commonly used cables. 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. DUPLEX VS MULTIPLE STRAND FIBER 40/100GB 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 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 *MTP is a registered trademark of US Conec Ltd

3 FOR BEST PRACTICES AND EXPERT CONFIGURATION CALL MTP MULTIPLE STRAND CONNECTORS AND FIBER POLARITY Understanding 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. 12-FIBER 24-FIBER 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 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 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. 40/100GB 8-FIBER QSFP Pins 1-4 = Transmit (TX) Pins 9-12 = Receive (RX) Pins 5-8 = not used 100GB 20-FIBER CFP Pins = Transmit (TX) Pins 2-11 = Receive (RX) Pins 1,12,13,24 = not used KEY = TX = RX = NOT USED 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. TYPE A POLARITY SIDE A KEY-UP SIDE B KEY-DOWN TYPE B POLARITY SIDE A KEY-UP SIDE B KEY-UP TYPE C POLARITY SIDE A KEY-UP SIDE B KEY-DOWN UNIVERSAL POLARITY SIDE A KEY-UP SIDE B KEY-DOWN POLARITY A CHANNEL ALIGNMENT - Opposing connectors have the same fiber channel positions except one end is key-up and the other is key-down. 12 FIBER SEQUENCE SHOWN Side A Channels: Side B Channels: POLARITY B CHANNEL ALIGNMENT - Opposing connectors are both key-up with the fiber channel positions reversed at each end. 24 FIBER SEQUENCE SHOWN Side A Channels: Side 5 Channels: POLARITY C CHANNEL ALIGNMENT - Opposing connectors are key-up and key-down with the adjacent fiber channel pairs alternating - channels 1 to 2 and 2 to 1, 3 to 4 and 4 to 3, etc. 12 FIBER SEQUENCE SHOWN Side A Channels: Side B Channels: UNIVERSAL POLARITY CHANNEL ALIGNMENT - Channel alignment is the same as Polarity B except the opposing connectors are key-up and key-down. 12 FIBER SEQUENCE SHOWN Side A Channels: Side B Channels:
