100G Lambda MSA releases specifications for 100GbE for up to 40 km
The 100G Lambda Multisource Agreement (MSA) Group has released three new specifications that extend single-mode reach of single-lambda 100 Gigabit Ethernet (100GbE) to up to 20, 30, and 40 km, respectively. The specifications are labeled 100G-LR1-20 for 20 km, 100G-ER1-30 for 30 km, and 100G-ER1-40 for 40 km.
The new specifications build on the MSA’s original set, which topped out at 10 km (see “100G Lambda MSA updates specifications”). “Single-wavelength 100G PAM4 optical technology has gained industry-wide adoption,” commented Mark Nowell, 100G Lambda MSA co-chair. “These longer-reach specifications will further accelerate broader industry acceptance of single-wavelength 100G solutions, especially for service providers and carriers who are in high demand of efficient and cost-effective optical solutions for next generation wireline and wireless networks.”
“The MSA has its mission to promote 100G per wavelength PAM4 technology as part of optical networking roadmap,” added Jeffery Maki, the other 100G Lambda MSA co-chair. “These new specifications support roadmap evolution for extended reaches of up to 40 km for today’s implementations and ready to migrate to higher electrical lane speed, smaller form factors, and lower power dissipation.”
The MSA also has addressed 400GbE based on 4x100G wavelengths. The group tackled 400G-FR4 early in its tenure and released specifications for 400G LR4-10 10-km applications last month. The MSA says it next plans to address 400GbE requirements beyond 10 km.
