Fiber Optic Attenuator is one kind of optical passive device which is used to debug the performance of the optical power in the optical communication system,debugging fiber optic instrument calibration correction, optical signal attenuation.And used for the attenuation of the input optical power, avoid optical receiver distortion due to input optical power powerful. The fixed fiber optic attenuator can achieve the dual function of adapter and attenuators.

Mobile network operation is increasing nowadays,SZOPT’s network infrastructures cable assemblies are keeping up with the continuous high-bandwidth growth,and excel subscribers’ expectations.What’s more,to add the capacity and coverage, we are involved in deploying distributed antenna system (DAS) networks and small cells.

Optical Cable Cross-connection Cabinet is used as the interface device at the splice of the trunk cable and wiring cable in the access network. It is mainly used for the connection, distribution and scheduling of the outdoor cables.The fiber capacity can be 12 core,24 core...288 core and 576 core max.

PLC splitter distribution box series are applicable in FTTH project and suitable for building’s outer walls application; They can distribute cables after installing splitters and also can draw out room fiber optic cables by direct or cross-connections. They are with the function of mechanical splice, fusion splice, light splitting, wiring distributions etc.

SZOPT offers a full range of CWDM&DWDM to meet the demand of applications such as: Gigabit & 10G Ethernet,SDH/SONET,ATM,ESCON,Fibre Channel,FTTx and CATV,etc.

Unmatched Low Cost, Mini Bypass Mechanical Optical Switch Low Optical Distortions High Isolation High Reliability Epoxy-Free Optical Path

Adapter type fixed attenuator is the female to female fixed fiber optic attenuator,whichutilizes the air gap between two connectors to achieve the optical attenuation. Fixed adapter type attenuator is simple, low-cost and compact. It is recommended for use where return loss is not a concern nor is absolute attenuation value.

Topscomm single/three phase power line carrier (PLC) communication module is developed on TCC081 series of PLC chips.

SZOPT offers a full range of CWDM&DWDM to meet the demand of applications such as: Gigabit & 10G Ethernet,SDH/SONET,ATM,ESCON,Fibre Channel,FTTx and CATV,etc.

RJ45 ethernet extension cables are widely used for lan network,such as home,office,cafe,hotel,etc.where the patch cable is not long enough,UTP,FTP,SFTP,etc.are available.

Variable in-line optical attenuators,also know as adjustable in-line optical attenuator or short as VOA, are used to permit dynamic control of optical power levels in a fiber. It can be applied to adjust power level of signal in the optical communication at the output of light sources, E/O converters and for the linear or dynamic range of power meter. Furthermore, they can the used in optical amplifier systems to balance the gain across the different operating wavelengths.
