North Carolina’s Research Triangle is acknowledged for solving mysteries, especially technical ones. That’s what will happen when three tier-one research universities – North Carolina State University (NCSU), Duke, and the University of N . C . (UNC) at Chapel Hill – and cutting-edge tech companies for example Sheathing line are throughout the triangle.
I ran across SEL while researching IEEE’s 802.3ba 40Gb/s and 100Gb/s Ethernet fiber-optic standard. Why was I putting myself through that? Well, before very long every commercial data center on the planet can have servings of its fiber-optic network migrated to 40Gb/s or 100Gb/s to stay competitive business-wise. Choosing the paper The Optical Fiber Ribbon Solution for your 10G to 40/100G Migration (PDF) created by SEL’s Bill Charuk, product manager, data center solutions, was especially fortuitous, as it answered several perplexing questions.
Ribbon-style cabling is important because OM3 and OM4 – the only real multi-mode fibers included in the 802.3ba standard – use parallel-optic transmission. Based on articles in the Cabling Installation & Maintenance site this means by design optical/electronic interfaces allow data to be transmitted and received over multiple fibers. In addition, it means 40G Ethernet interfaces comprise of four 10G channels on four fibers per direction, and 100G Ethernet interfaces use four 25G channels on optical fiber ribbon machine per direction as shown within the diagram below.
Profits: parallel runs are utilized to increase throughput bandwidth using either multiple fiber-optic cables or multiple fibers within a ribbon cable. To begin employing a ribbon cable over individual cables Charuk writes, “The use of ribbons provide for easier connectorization (less chance to cross fibers in a MPO connector), dexkpky80 perhaps moreover, achieve easier polarization continuity whatever the polarity method selected for your system.”
“Ribbon cables are already used in the telecom industry for over 2 decades,” writes Charuk. “These were brought to improve the fiber density inside a given cable and also to reduce cable costs. Of particular importance is fiber density, as fiber counts rise in the info center, it is really an attractive feature.”
Fiber-optic ribbon cables seem like a logical choice. “The overall combination of ruggedness of the ribbon design, fiber density, size, and relative cost points to ribbon to be best suited to both new and retrofit installations inside the data center,” concludes Charuk. “Additionally, the ribbons in Optical fiber coloring machine would be best designed for future expansion, since the transmission protocols progress to higher and higher data rates.”
