ADTRAN (NASDAQ:ADTN) has introduced an RF over glass (RFoG) solution with optical beat interference (OBI) mitigation technology. OBI is caused by simultaneous upstream optical transmissions by multiple cable modems, leading to impaired reception at all upstream frequencies. The solution is intended to support the reuse of existing CATV assets within both the headend and home.
"The need to support reliable voice and ultra-fast broadband is key to securing lucrative triple-play revenues for MSOs in a changing competitive landscape," said Erik Keith, principal analyst, GlobalData. "As MSOs look to build out their fiber infrastructure to support rich video content, ADTRAN RFoG OBI solutions allow them to deliver the requisite customer experience while accelerating FTTH service by reliably reusing their existing RF infrastructure."
ADTRAN's RFoG solutions feature an OBI mitigation MicroNode that does not require new centralized cabinet construction. The scalable ADTRAN RFoG OBI solution is intended to provide a distributed approach to OBI mitigation and to smooth the transition to FTTH networks and IPTV-based triple-play services.
"By deploying our MicroNodes, ADTRAN cable MSO customers are afforded a more simplified approach to OBI mitigation and FTTH expansion, one that is compatible with both 1G and 10G EPON and transparent to the existing CATV assets like in-home set top boxes," said Hossam Salib, vice president of cable and wireless strategy at ADTRAN. "MSOs are not only looking for these critical RFoG advantages, but demand an OBI mitigation that avoids constructing centralized cabinets that delay time-to-market and require a large amount of up front capital. The ADTRAN RFoG solution is the next evolution as we continue to expand our presence within the cable MSO access network."
