The scheme of optical fiber direct connection for 5G fronthaul.
Gigalight provides wireless fronthaul network customers with industrial-grade SFP/SFP+ modules.
The network architecture of above-mentioned WDM PON 5G fronthaul is with technical features.
In 4G LTE, fronthaul networks rely on semi-proprietary protocols such as CPRI and OBSAI.
The transparent transmission management function of WDM PON 5G fronthaul adopts AMCC technology route.
Meanwhile, the fronthaul to 5G needs a strong optical network due to the flat network architecture.
It can be seen from table 1 that the 25G tunable laser is not fully mature at present,applied to 5G fronthaul network.
So the optical devices used in the fronthaul and middlehaul need to meet the use of outdoor scenes.
In order to support high data rates and low latency needs of 5G,the access network and fronthaul have been revamped.
These splits create two transport segments: fronthaul, between the RU and DU, and midhaul, between the DU and CU.
Compared with the current 3G/4G network,the biggest change of 5G in wireless load-bearing network is the fronthaul and middlehaul.
For CPRI wireless fronthaul networks, Gigalight has developed a complete set of industrial-grade SFP, SFP+ and SFP28 optical transceivers.
Ethernet networks are a shared medium,so it is important to prioritize fronthaul packets over other lower-priority packets.
In the fronthaul scenario, most of the transmission distance is below 10km, of which less than 5km accounts for about 80%, and 5km to 10km accounts for 20.
This standard enables deterministic connectivity for fronthaul streams within ubiquitous and flexible Ethernet-bridged networks.
OLT devices carry the midhaul service between DU andRRU at the same time that OLT device realizes the fronthaul service between DU and RRU.
In the 4G era, the demand for optical transceivers in the fronthaul network was dominated by single-mode 10G duplex optical transceivers.
In the 5G era, new network architecture, various new technologies andapplication characteristics have put forward new demands and challenges to the fronthaul network.
At the same time, 5G has new challenges for the fronthaul network, such as a lot of new demands on dense optical fiber deployment, higher transmission broadband and low latency.
By using these standards-based approaches to enhance Ethernet,operators will get a deterministic network that can address stringent fronthaul requirements.
In the 5G era, the fronthaul network will still be dominated by fiber-optic direct drives, but new requirements are imposed on the speed and optical port of optical transceivers.
The Gigalight industrial 6G CPRI SFP+ mobile station optical transceivers(GPP-xx6G-xxT)are designed for 6Gbps CPRI Mobile Fronthaul links reach up to 300m-80km over dual fibers.
New services like self-driving vehicles demand higher capacity in the fronthaul, backhaul and metropolitan optical networks that connect 5G wireless access points with data centers.
Gigalight's optimized optical devices provide highly differentiated performance, power, size andcost solutions for next-generation Cloud Data Centers, 5G Fronthaul Network, and Long-haul Metro Transport applications.
OLT can achieve xHaul(Fronthaul and Midhaul)sharing a device, OLT platform can be deployed in a computer room with DU pool, reducing the costs of associated equipment and computer room construction.
The Gigalight industrial 25G DWDM SFP28 optical transceivers are designed for Data Center 25G Ethernet and 5G Fronthaul CPRI/eCPRI links reach up to 10km over Single-Mode Fiber SMF.
This includes the 5G wireless Radio Access Network(RAN) fronthaul where new optical transceivers bring 100 Gbps optical connectivity from the remote radio head(RRH) to the baseband unit(BBU) or central office.
These include the crucial 5GXCrosshaul project which aims to integrate fronthaul networks(5G wireless networks) with backhaul networks(which are largely fibre optic) in the transport of data.
It has unique advantages in the application of 5G fronthaul transmission. Via the breakthroughs in key technologies such as efficient and flexible networking structure, low cost, high-speed, colorless ONU technology and AMCC, the construction of low-cost and high-performance fronthaul solutions will definitely be the new impetus to 5G technology development and business.
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.
