R&M has randomly selected eleven MTP OM4 Trunk cables to do a link test over a distance of 675 metres. The test series was conducted to confirm the outstanding performance of components, assembling capabilities and internal test methods. The aim was to reach a bit error ratio (BER) that is better than 10-12, exceeding a period of 13 hours has been more achieved and the outstanding quality of R&M's high-performance network connectivity solutions was more than confirmed. The measurements were conducted at the R&M laboratories.
Gaurav Ahluwalia, Managing Director, R&M India, said, "Parallel optics are been established in the data center infrastructure world during the recent years. The usage of this technology leads to more challenges for engineers, planners and data center managers. Link lengths needs to be planned more carefully than ever before. Cabling systems should be selected taking loss budgets and link segments very detailed into consideration."
IEEE addresses high-speed Ethernet in a number of ways. Depending on required distances, the speed foresees IEEE 802.3ba different transmission methods. The 100GBASE-SR10 substandard plays an important role for short-range applications. It defines the transmission of 100Gbit/s over multi-mode fiber using cost-effective 850 nm lasers. The serialized data gets delivered by ten lanes of multi-mode at a rate of 10Gbit/s per lane. Due to the limited IL budget with OM4 fibers the standard foresees a maximum reach with of 150m only.
