Product Description

4-Port 10/100T + 2-Port 100/1000X SFP Industrial Ethernet Poe Switch

Flexible, Reliable and Industrial-grade Network Distance Extension Solution:
The Takfly TK-2SF4D is an Industrial 6-port full Gigabit Ethernet Switch providing non-blocking wire-speed performance and great flexibility for Gigabit Ethernet extension in harsh industrial environment. It provides 4-port 10/100/1000Base-T RJ-45 copper and 2 extra 100/1000Base-X SFP fiber optic interfaces delivered in an IP30 rugged strong case with redundant power system. The TK-2SF4D is well suited for applications in deploying surveillance system, and securing control and wireless service in climatically demanding environments with wide temperature range from -40 to 85 degrees C.

Fiber-Optical Link Capability Enables Extension of Network Deployment:
The two SFP slots are compatible with 100Base-FX or 1000Base-SX / LX / WDM through SFP (Small Form Factor Pluggable) fiber-optic transceivers. The fiber optical uplink capability guarantees the throughput to all nodes hooked into the network and the Gigabit Ethernet distance can be extended from 550 meters (Multi-Mode fiber cable) up to 10/20/30/40/50/70/120 kilometers (Single-Mode fiber cable), also the Fast Ethernet distance can be extended from 2km (Multi-Mode fiber cable) up to 20/40/60 kilometers (Single-Mode fiber cable). They are well suited for applications within the factory data centers and distributions  

Adjustable 6-Port Switch Mode or 4 + 2 Fiber Redundant Mode:
The two SFP slots allow to change the operation mode with its built-in DIP switch. Via the built-in DIP switch, the TK-2SF4D can be configured as 6-port Ethernet switch or 4+2 fiber redundant mode. With the 6-port switch mode, the TK-2SF4D can operate in Store-and-Forward mechanism with high performance; on the other hand, when in the 4+2 fiber redundant mode, it provides rapid fiber redundancy of link for highly critical Ethernet applications. The redundant mode also supports auto-recovering function. If the destination port of a packet is link-down, it will forward the packet to the other port of the backup pair.  

Environmentally Hardened Design
The TK-2SF4D is equipped with the slim-type IP30 metal case for easy deployment in heavy Industrial demanding environments. With IP30 industrial case protection, the TK-2SF4D provides a high level of immunity against electromagnetic interference and heavy electrical surges which are usually found on plant floors or in curb side traffic control cabinets. Being able to operate under the temperature range from -40 to 85 degrees C, the TK-2SF4D can be placed in almost any difficult environment. The TK-2SF4D also allows either DIN rail or wall mounting for efficient use of cabinet space.

Convenient and Reliable Power System:
To enhance the operation reliability and flexibility, the TK-2SF4D is equipped with two DC power input connectors for redundant power supply installation. It also possesses an integrated power supply source with wide-ranging voltages (12 to 48V DC or 24V AC) for worldwide high availability applications requiring dual or backup power inputs.

Hardened Environment Application:
The TK-2SF4D Industrial Gigabit Ethernet Switch offers full port Gigabit speed. It provides very high reliability and security features to make sure the continuous operation in harsh environments such as control cabinet of transportation, factory, outdoors and places where extreme low or high temperatures can be experienced. Moreover, the TK-2SF4D is also compatible with 100Mbps and 1000Mbps SFP transceivers to provide a strong, stable and long-distance connection and flexible industrial networking deployment.

Redundancy Application:
The TK-2SF4D Industrial Gigabit Ethernet Switch provides rapid fiber redundancy of link for highly critical Ethernet applications. The redundant-mode supports auto-recover function. If the destination port of a packet is link-down, it forwards the packet to the other port of the backup pair.

Physical Port:
> 4-port 10/100/1000Base-T RJ-45 with auto MDI / MDI-X function
> 2-port SFP slot interface, SFP supports 1000Base-X and 100Base-FX transceiver via DIP switch configured

Fiber Port Redundancy:
> Link status auto-detect and redundant on Dual ports with the same connector type
> Only Primary-Port is active at a time, the Backup-Port is blocked
> When Primary-Port link failure occurs, the traffic will swap to Backup-Port automatically.
> Once the Primary-Port status is back to link-up, the traffic will swap from Backup-Port to Primary-Port.

Layer 2 Features:
> Supports Auto-negotiation and 10/100Mbps half / full duplex and 1000Mbps full duplex mode
> High performance Store and Forward architecture, runt/CRC filtering eliminates erroneous packets to optimize the network bandwidth
> Prevents packet loss with back pressure (Half-Duplex) and IEEE 802.3x PAUSE frame flow control (Full-Duplex)
> 9K Jumbo Frame Size support
> Backplane (Switching Fabric): 12Gbps
> Integrated address look-up engine, support 1K absolute MAC addresses
> Automatic address learning and address aging
> CSMA/CD Protocol
