R&M successfully tested 100G transmission with 850nm laser technology over a reach of 675 meters
The MPO Connector from R&M
IEEE prescribes a number of ways to address high speed Ethernet. Depending on required distances and speed, IEEE 802.3ba foresees different transmission methods. For short range applications, the 100GBASE-SR10 substandard plays an important role. It defines the transmission of 100Gbit/s over multi-mode fiber using cost effective 850 nm lasers. Ten lanes of multi-mode fiber deliver serialized data 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.
Passed with excellent results
A series of MTP® Trunks consisting of different lengths from 5 meters up to 160 meters was randomly selected. With caution the different adapters and plugs were cleaned to form a 675 meter link with 10 MTP® adapters in-between. Commercially available 100GBASE-SR10 CFP full-duplex transceiver modules where used to transmit Ethernet packets at 850 nm wavelength. For the throughput simulation, frame sizes of 64-, 128-, 256-, 1024-, 1280-, 1518- and 9000 Bytes where defined to analyse the theoretical versus the actual throughput. After 13hours, 23minutes and 38seconds the test was considered to be completed. Not a single packet was lost during the entire duration of the test. For details see the original Xena Network RFC 2544 report.
Parallel optics has been established in the data center infrastructure world during 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.
R&M’s HD MPO multi-fiber solution sets standards for port density and efficient use of space, for flexibility and safety as well as for convenient planning and installation. The system is particularly attractive to
