 24ports 100/1000Mbps SFP + 4 Combo port 10/100/1000Mbps RJ-45 + 100/1000Mbps SFP slot Managed Ethernet Access Switch


Connection Technology Systems (CTS) FOS-3128 is a layer2+gigabit access switch equipped with 24 dual-speed SFP slots and 4 combo uplink ports (10/100/1000Mbps RJ-45 + 100/1000Mbps SFP slots). All SFP slots can accommodate wide range of SFP transceivers including single-mode, WDM or CWDM transceivers. FOS-3128 is perfect for service providers and enterprises who plan to implement FTTX or Metro Ethernet networks, with further spanning into triple-play service

FOS-3128 delivers wire-speed throughput for data, voice and IPTV services, using non-blocking 56Gbps switching fabric. 1+1 power supply design can provide seamless power changeover to reach sustainability of power if one of power supply has failure. AC and DC powers can be mixed in the same unit for deployment flexibility

Many service providers are extending their existing data service with triple-play service because it can generate higher revenue return by combining data, voice and IPTV in one box. Advanced features including MVR**, IGMP snooping, IGMP fast leave, IGMP filtering, various QoS classifications and rate limit control facilitate service providers to deploy a manageable network environment and deliver a successful triple-play service

In order to provide customers extra security and separation, FOS-3128 has come with QinQ feature. This feature enables service providers to separate different customers at layer2 level no matter what VLAN setting the end customer has

With carrier-grade in mind while keeping user-friendly for administrators, FOS-3128 can be easily managed by web interface, console, telnet CLI, SNMP and DHCP auto-provision


IPv4/IPv6 dual stack

Support IPv6 management, packet forwarding and MLD v1/v2 Snooping

SFF-8472 Diagnostic Monitor Interface

Allow administrator to view SFP information and status including speed, distance, vendor ID, vendor S/N, temperature, voltage, TX bias, etc

Rich in Functions to Facilitate Multimedia Streaming

Support IGMP snooping, IGMP fast leave, IGMP filtering & advanced MVR** to intelligently transmit multicast traffic and deliver IPTV service

Q-in-Q VLAN Tagging

Allows service providers to implement Metro Ethernet service while maintaining the layer-2 separation of different customers

IEEE 802.3ad Link Aggregation

A cost-efficient way to increase bandwidth and reliability by grouping multiple links into one

Power Down Trap

Popular SNMP trap message to rapidly identify network fault due to power outage and reduce truck rolls to save OPEX for service providers

Power Supply Redundancy

By combining two power sources (2AC or 2DC or 1AC+1DC), power redundancy can be well achieved

Target Applications

FTTX Metro Ethernet implementations
