When revenue per bit starts falling and cost per bit starts increasing, it’s time to think about alternative strategies to expand Transmission/IP network. As IP is predominant traffic in Transmission networks, therefore …
Are you concerned about latency in your data center links running over optical network ? Or, are you planning for Data Center Interconnectivity in near future and want to …
What your DWDM vendor did not tell you about latency for your Data Center Interconnect Read More »
If an Operator decides to deploy Multi-layer protection using both IP/MPLS and Optical domain, he faces a number of challenges: IP/MPLS and Optical control planes work separately in transport networks; they are, usually, disjoint …
Research firm, Heavy Reading, defines “P-OTS as a platform that combines SONET/SDH, connection-oriented Ethernet, DWDM and, depending on where the platform is used within the network, also optical transport network …
The past year was hectic in terms of discussions regarding what could the next client rate for Ethernet and at the same time discussions were going on to decide the …
OSNR ( Optical Signal to Noise Ratio) is a critical and important parameter in high speed DWDM links. If OSNR is not good it will seriously affect the distance reachability …
As data rates increase beyond 10G, the requirements for OSNR become stringent. This is because the advanced modulation techniques used at higher bit rates require higher OSNR performance. Low OSNR …
Soft Decision FEC ( SD FEC) versus Hard Decision FEC Read More »
The debate still lingers on. When it comes to protection and re-routing on High speed links, what is the benefit of using Optical ASON versus Electrical ASON. The Optical ASON relates …
