Italian wholesale network reseller Open Fiber has reported the successful completion of tests on its ZION photonic backbone network. The tests on ZION, billed as Italy’s first scalable 200 Gbits/s long haul network, were conducted on the Rome to Florence section of the infrastructure. ZION is also the first Italian optical network to use Huawei’s Reconfigurable Optical Add/Drop Multiplexers (ROADM) and Flex Grid solutions. The passive optical fibre infrastructure is provided by energy group Terna.
According to Open Fiber, the significance of ZION lies not only in its capacity of 200 Gbits/s per optical channel, but also in its scalability: with a simple software command, ZION can transmit data at 100, 200 and even 400 Gbits/s, depending the needs of the managed service and the conditions of the optical link. The network is expected to enter service at the end of March.
“Where typically the big fibre links stop at 40 Gbits/s in Italy, we are the first in Italy and among the first in Europe to achieve these performances”, explains Stefano Paggi, Director of Network & Operations Cluster C and D of Open Fiber.
With the Flex Grid product it will be possible to aggregate multiple optical channels simultaneously on a single optical fibre and therefore manage more and more customers and services. This will additionally point the way to enabling Open Fiber to fully exploit the very high transmission band of the fibre at the Terabit range.
In other Open Fiber news, earlier this month the company inked an agreement with Rome-headquartered utility ACEA to begin the development of a FTTH broadband communication network that would reach 1.2 million homes and premises in the capital in 5 years. That scheme was costed at €375 million, €350 of which will be provided by Open Fiber.
