Telefónica Tests Huawei's 100G

Telefónica has completed a trial of 100 Gbps transmission using Huawei Technologies' OSN 6800 WDM/OTN transport platform. The 100 Gbps trial link spanned Valladolid to Zaragoza, a total transmission distance of 1022 km, without electrical regeneration.


The field trial in Spain was based on Huawei' s OSN 6800 WDM/OTN transport platform with the transponder inserted in subracks. The fiber type used was standard G.652, and single lambda rate is up to 112Gbps. The link passed through 20 spans with the concatenation of 10 sets of ROADM, 33 EDFA amplifiers and 2 sets of MUX/DEMUX. Arbitrary mixed 10G/40G/100G transports with 50Hz channel spacing were also achieved. A smooth upgrade from 10G to 40G/100G was supported without interfering with the existing network, thereby protecting the operator' s original investment.
