400G-capable optical transceiver increases 400G and 100G infrastructure

To address the demands of enterprises worldwide, seeking to deliver faster speeds and higher bandwidth, AddOn Networks has introduced the QSFP28-DD 2x100G optical transceiver. It increases network density, reduces infrastructure investments and solves interoperability issues between current and future infrastructure, claims AddOn.

“At a time when new technologies such as 5G are driving greater traffic onto networks, it is vital that enterprises and data centres deliver high-quality, large-capacity connectivity to meet the needs of businesses and consumers,” said Patrick Beard, chief technology officer at AddOn Networks. The QSFP28-DD 2x100G transceiver enables network expansion at a multitude of levels while keeping expansion costs to a minimum, he added.

The QSFP28-DD 2x100G transceiver provides enterprises facing scaling challenges the upgrade to a 400G PAM4 infrastructure. It is also suitable for customers who require an interim step as they wait for a more mature solution, advises AddOn. The QSFP28-DD 2x100G solves the interoperability problems that have been experienced between legacy infrastructures and newer systems by using two non-return to zero (NRZ) connectors for compatibility to deliver bandwidth and speed upgrades.

The QSFP28-DD 2x100G transceiver consists of a high-density CS connector and contains two 100G transceivers in one housing, enabling the subtending of two common 100G NRZ to the network. Two 100G transceivers offer flexibility for future-proofing infrastructure and allow enterprises to invest in the relieving of network bottlenecks at minimal expense, says AddOn. The transceiver is also interoperable with existing 100G-CWDM4, 100G-LR4 and 100G-4WDM10 transceivers.
