DM4615 16GPON
Standalone GPON OLT

GPON (Gigabit Passive Optical Network) is a solution for optical access networks, offering high speed, cost-effective broadband applications and Triple Play services (voice, video and data). This technology allows sharing fiber optics among customers, reducing cost and maximizing the use of bandwidth.

Datacom has a range of GPON products that enables complete solutions of any size and cost-effective to provide FTTx services. The GPON product line is compliant with ITU-T G.984 and ITU-T G.988. Each GPON link supports downstream rates of 2.488 Gbit/s and upstream rates of 1.244 Gbit/s and offers dynamic bandwidth allocation (DBA).

The DM4615 OLT 16GPON is a compact and economical 1U solution for providing FTTx services. It supports 16 x GPON, 4 x 1GE (RJ45 ) and 4 x 10GE ports using SFP+ connectors. This model supports 2048 subscribers (ONU / ONT) whose network configurations are made remotely via the OMCI protocol in accordance with ITU-T standards. The DM4615 can remotely configure the main parameters of the ONU / ONT DM984-420 and DM984-422 (PPPoE, Fixed IP, DHCP, Bridge and WLAN).

Supports AC or DC power using independent, redundant, and hot-swappable power supplies. Offers hot-swappable FAN module.

Triple Play Broadband Services

Through optical access, GPON technology allow convergence of data, voice (VoIP) and video (IPTV) in a single access.



Business services

The DM4610 provides a number of features that enable data, voice and video delivery to small, medium and large businesses.

The TLS (Transparent LAN Service) feature together with the Hairpin feature allows you to offer LAN-to-LAN services without additional equipment - such as routers.



FTTD – Fiber to the Desk

GPON FTTD simplifies the network by replacing the switches typically by a central OLT and ONUs in the users, reducing the network infrastructure using passive elements, fiber optics and point-multipoint topology.
