On the other hand, Huawei, a leading global information and communications technology (ICT) solutions provider, had announced that it has developed an embedded optical time domain reflectometer (eOTDR) prototype with a largest-in-industry split ratio of up to 1:64. Huawei's new eOTDR prototype offers cost-effective fiber maintenance by embedding OTDR functionality into an optical line terminal (OLT) PON optical module and operating at the same wavelength as user data. OTDR-embedded optical modules are the same size as common optical modules and can be easily deployed on FTTx for troubleshooting. This approach does not require engineering reconstruction such as fiber connection changes or adaptation of optical network terminals (ONTs), nor does it interrupt services during troubleshooting. Utilizing this approach effectively improves fiber troubleshooting efficiency and reduces costs, setting the eOTDR prototype up for promising market prospects.

Topstar is one of the  leading manufacturer for PON family of modules, including a full line of GPON, GEPON and 10G PON modules, as well as the Multimode Coupled Receiver (MCR) OLT module. Our main products are the SFP, SFP+, XFP, CFP, CFP2, CFP4, QSFP+ QSFP28 as well as the CWDM, DWDM,  GPON, EPON SFPs.
