FTTx Gigabit Optical Network Unit



The PBN PM620 is the successor of PBN’s successful PM520 product, featuring the latest industry chipset and added support for the ITU-based GEPON standard. With wire-speed switching, NAT speed upto 900 Mbps, this device helps distribute the FTTH experience within the consumers home. Wi-Fi speeds of up to 600 Mbps with triple-antenna 802.11 AC standard as well as backward compatible 802.11 b/g/n connects all devices in a user's home seamlessly. With public Wi-Fi network offerings by MSOs becoming more popular every day, the PM620 supports up to 4 SSIDs which allow the re-use of the high-speed infrastructure without impacting the end-user's experience.

Same as in the previous product families, PM620 CPE comes with embedded VoIP, Wi-Fi and routing capabilities, as well as with PBNs optional full-band CATV receiver for dual- and single-fiber deployments. With TR069 provisioning capabilities out of the box, the new CPE can be used either in conjunction with NMSE or the provider's incumbent provisioning system.

  • Service access over IEEE802.3ah GEPON
  • 4x 10/100/1000 Mbps routed/bridged user ports with auto cross-over (MDI/MDI-X)

  • High-performance optical CATV receiver delivering full-spectrum television from 45 to 1000 MHz
  • CATV Module removable by customer
  • Controllable optical Automatic Gain Control (AGC) circuit, to maintain a constant RF-Output level at the CATV module
  • IPv6 supported
  • SIP VoIP functionality with two physical RJ11 ports
  • 802.11 a/b/g/n/ac Wi-Fi capability

PM620 is ideal for use in commercial and residential installations when value is a priority. The application diagram shows a typical hybrid HFC-FTTx scenario with CATV overlay utilizing PBN's AIMA3000.

Due to its extensive feature set, PM620 is very competitive in fiberto-home and hospitality businesses where multiple Wi-Fi SSIDs, IPTV, and security applications are used in a dense short-haul deployment. Integrated into a single management system, the entire HFC-FTTx environment is able to be monitored and provisioned by the operator from a single screen.

For the CATV overlay components, PBN's 1RU EDFA and LTE product line can be used, instead of the larger AIMA3000 carriergrade RF headend solution, based on operator needs.
