Introduction:
In this article we will discuss about the 10GBASE-EW Ethernet standard and what is the difference between 10GBASE-EW and 10GBASE-ER, So you can have a basic understanding for 10GBASE-EW technology to understand the basic solutions to 10GBASE-EW.
What is the 10GBASE-EW technology?
10GBASE-EW was designed to interoperate with OC-192/STM-64 SDH/SONET equipment using a light-weight SDH/SONET frame running at 9.953 Gbit/s.10GBASE-EW can drive maximum link distances up to 80 km depending on the fiber standard employed. Its Physical Coding Sublayer 64b/66b PCS is defined in IEEE 802.3 Clause 49 and its Physical Medium Dependent PMDs in Clauses 52. It also uses a WAN Interface Sublayer (WIS) defined in Clause 50 which adds extra encapsulation to format the frame data to be compatible with SONET STS-192c.
What is the Difference Between 10GBASE-EW and 10GBASE-ER?
10GBASE-EW Supports 64B/66B signal encoding type and it is compatible with transmissions over OC-192 SONET based optical fiber system.
10GBASE-ER ("extended reach") is a port type for single-mode fiber and uses 1550 nm lasers. Its Physical Coding Sublayer 64b/66b PCS is defined in IEEE 802.3 Clause 49 and its Physical Medium Dependent PMD in Clause 52. It delivers serialized data at a line rate of 10.3125 Gbit/s.
