16 PON Port GPON OLT (DT-GOLT-1016S)-Layer 2 Switching


DT-GOLT-1016S completely meet relative standard of ITU G.984.x and FSAN, which is 1U rack-mounted device with1 USB interface, 4 uplink GE ports, 4 uplink optical ports, 2 10-gigabit uplink ports and 16 GPON ports, each GPON port supports the splitting ratio of 1:128 and provides downstream bandwidth of 2.5Gbps and upstream bandwidth of 1.25Gbps, system support 2048 GPON terminals accessing in for the most. This product meets the requirements in device performance and size of compact server room as the product has high performance and compact size, is convenient and flexible to use, and is easy to deploy as well. Moreover, the product meets the requirements of promoting network performance, improving reliability and reducing power consumption in the perspective of access network and enterprise network and is applicable to three-in-one broadcast television network, FTTP (Fiber to the premise), video monitoring network, enterprise LAN (Local Area Network), internet of things and other network applications with a very high price/performance ratio.




Meet ITU-T G.984/G.988 standard and relative GPON standards of Chinese Communication Industry

Support OMCI remote management for ONT/ONU, compatible with ITU-T G.984.4/G.988 OMCI Protocol

1U height 16PON OLT product in compact design of Pizza-Box

Layer 2 Switching Function

OLT equips with very powerful layer 2 Full Wire Speed Switching and completely supports layer 2 protocol. With working mode of switch, isolate and one by one, OLT supports varieties of layer 2 functions like TRUNK, VLAN, rate limit, queue technology, flow control technology, ACL and so on, which provides technical guarantee for the development of multi-service integrated.

Layer 3 Switching Function

OLT supports layer 3 static router and multicast router

QOS Guarantee

GPON Products maintains fully-improved DBA with excellent Qos service capabilities. DBA meets different Qos requirements from different service flow in latency, jitter, packet loss rate.

Easy-to-Use Management System

Support management method of CLI, SNMP, TELNET, SSH and WEB and meet OMCI standard, through OMCI channel protocol service management can be realized, including ONT function parameter set, T-CONT business lines and amount, Qos parameters, configuration information request, performance statistics, auto-reporting of running events in system, configuration for ONT from OLT, fault diagnosis and management of performance and safety.
