Atx Maxnet Ii 300x180For the upcoming ANGA Cable Show in Germany, ATX Networks has further developed its MAXNET II platform for HFC and RFoG/PON deployments. For HFC, ATX will demonstrate a platform that includes optical transmission and reception, narrowcast combing and return path splitting for up to 50 node segments in one rack. For RFoG/PON, the company has integrated all the distribution and receiving components required for delivery to 1,280 ONU/Ts into one 3RU module.

ATX's F-connector based 1,310 nm transmitter and return path receiver offer integrated eight-way passives. An MCX-to-F conversion patch panel has been added that does not take any more space than the base 3RU chassis, and allows hot-swapping modules without rewiring of any cable. Included are front access fiber ports and test/insertion ports, as well as individual port attenuation to balance all narrowcast content independently. Applications of up to 50 node segments, forward and return, are possible in one 40RU rack, including passive combiner/splitters. It's intended for DOCSIS 3.0 deployments, even with reduced CMTS port output levels due to channel bonding.

The company's RFoG/PON module integrates a 1,550 nm transmitter, a high output EDFA, four-way optical splitter, optical filters for RFoG return path wavelengths, optical filters for PON wavelengths, as well as a quad-pack low noise RFoG receiver with <1.5pA/rtHz sensitivity. Each module is designed to service four groups of 32 ONUs. Ten such modules fit into one 3RU chassis, with redundant power supplies, resulting in up to 1,280 ONUs served in 3RU. Other options include an RFoG only module (without PON support) and PON module with 1,550 overlay (without RFoG receivers).
