  • The Introduction of Optical Transceivers for 5G Networks

    The demand for the 100G optical transceiver by the 5G network is very urgent. At present, there are many kinds of mature 100G optical transceivers in the market such as 100G QSFP28 optical transceivers and 100G CFP-DCO optical transceivers provided by Gigalight. This article will introduce the optical transceivers can be provided by Gigalight for 5G fronthaul, midhual and backhaul, especially, 25G BiDi Fronthaul Solution, 100G QSFP28/200G QSFP56 Midhaul/Backhaul Solution. First of all, let’s see the demand for optical transceivers by 5G.

  • Ethernet for 5G Fronthaul

    5G promises to deliver higher speeds and support revolutionary new use cases, services and applications that connect people and things. No previous RAN technology has been expected to support such a wide range of services with different capacity, latency, synchronization, reliability and connectivity requirements. Operators cannot meet these expectations by building the 5G RAN in isolation from other network domains, including the transport layer. Besides the upgrades to the RAN—which include cell densification, more antennas (i.e. massive MIMO) and the use of existing and new operating frequencies—operators need more fiber and new packet transport technologies that address the diverse applications and corresponding network requirements. Where possible, their 5G plans should leverage existing packet networks to save on cost and speed deployment. 5G was not intended to operate independently or replace existing 4G networks. Rather, 5G radios were engineered to complement existing resources. This is evidenced by a thrust of non-standalone (NSA) configurations in early deployments where the 5G radios attach to the 4G packet core network and use 4G LTE for coverage and 5G for capacity infill. Having overlay networks…
