Electro Standards Laboratories (ESL) announces the release of the Model 6325R 16-Channel ST Simplex SMF Fiber Optic Switch. Engineered for high-reliability environments, the Model 6325R provides seamless, manual pushbutton and remote-controlled switching of 16 independent fiber optic channels, allowing users to redirect data paths or isolate network segments with commands via Telnet or a user-friendly Graphical User Interface (GUI).

As modern networks demand greater flexibility and security, the Model 6325R delivers a robust solution for managing Single Mode Fiber (SMF) connections. Utilizing MEMS-based mirror/prism technology, the switch ensures transparent data transmission without the need for optical-to-electrical conversion.

Key Features of the Model 6325R:

  • 16 Independent Channels: Simultaneously or independently switch 16 ST Simplex channels between "A" and "B" positions.
  • Manual Control: 16 pushbuttons for secure local control of the switch positions. 
  • Remote Management: Fully controllable via Telnet and a web-based GUI, allowing for instant network reconfiguration from any location.
  • MEMS Technology: All-optical (O-O-O) switching maintains signal integrity with low insertion loss.
  • Reliability: The unit retains its last known position during power loss and is housed in a rugged 2U rackmount chassis.

The Power of SMF Simplex Fiber Optic Switching:

The Model 6325R is specifically optimized for Single Mode Fiber (SMF). Unlike multimode fiber, SMF allows for significantly longer transmission distances and higher bandwidth. By utilizing a Simplex configuration, the switch maximizes fiber infrastructure efficiency, requiring only a single strand for one-way data flow.

Core Benefits:

  • Cost Efficiency: Reduces the need for manual labor and "hands-on" cable management in the data center.
  • Redundancy and Reliability: Facilitates the creation of redundant network paths, allowing the signal to be rerouted in case a fiber or path fails, thus ensuring high availability and minimizing downtime.
  • Versatile Monitoring and Testing: Multi-channel fiber monitoring and multi-position source/detector selection.
  • Scalability: The high-density 16-channel design fits into a standard 19-inch rack, saving valuable floor space while providing massive switching capacity.

The Model 6325R is a great addition to the QuickSwitch® line combining ESL’s proven optical switching technology with remote management tools like Telnet and a web GUI. The Model 6325R provides network administrators a robust tool to manage complex fiber infrastructures with unprecedented precision.
