Application of C-Light Optical Module in Telecom Operator Optical Network (2024)

Posted on：September 1, 2024 by C-LIGHT

According to the market demand of telecom operators and the characteristics of optical communication technology, several typical optical communication network applications of operators are as follows: 5G mobile network, metro transmission network, optical access network and data center network. Because the C-Light optical modules have professional quality of low power consumption, long distance, high temperature resistance, excellent compatibility, 400G~1G full-length product line and fast business response& delivery capability, which has won the reputation in many operators and customers worldwide.

Optical module application in 5G mobile network

The DU part of the AAU connection in the 5G mobile network is called 5G Front-haul. The main optical modules used in this field are 25G SFP28 1.4km 500 m 100m optical modules.

The part of the DU connecting the CU is called Middle-haul. The optical module mainly used is the 50G QSFP28 BiDi 10km 40km optical module.

The communication network between the CU and the core network is called Back-haul. The optical modules mainly used in this project are 100G QSFP28 10km 40km 80km 100km optical modules.

Application of optical module in optical transport network (OTN)

Widely used DWDM/CWDM network architectures in OTN networks are optically-multiplied DWDM/CWDM optical modules and MUX DeMUX OADM. There are a large number of application requirements. Currently 400G/100G 300km/500 km Coherent DWDM Optical Modules and 25G 10G Multiply Optical Dispersion Compensator (DCM) 96-wave 40km/80km tunable and fixed wavelength SFP XFP optical modules are widely used. This series of optical modules have multi-rate universal quality and support both Ethernet and OUT series protocols.

Application of optical module in optical access network

Point-to-multipoint optical communication technologies in fiber to the home networks (FTTH) and passive optical networks (PON) require burst-mode XGSPON by optical networks GPON EPON OLT optical module and ONT STICK (optical cat stick) optical module. Today NOKIA, HUAWEI, ZTE and CALIX are the leading brands in this network application.

Optical module application in data center network

Base on that server, leaf switch, spine switch, operators require the optical module for high speed, low cost and short distance application, Rider Optical Networks introduces 800g 400g 200g 100g 50g 40g 25g 10g low-cost multimode SR DR FR PSM optical modules and DAC ACC AOC and other types of high-speed cables for these network applications. C-Light has special designed modules for operators who use HPE NOKIA JUNIPER CISCO CIENA brands.
