396-O9310 4E1 or 4T1 Fiber Optical Mux
Or call us on

This small standalone fiber-based network device is available in two versions: CPU and non-CPU.

The Loop-O9310 belongs to the Fiber Optical Mux product family and provides ideal solutions for building fiber-based E1 or T1 networks. It can multiplex up to 4 E1 or 4 T1 signals for transmission over an optical fiber, resulting in longer reach without repeaters and superior performance compared to copper media.

The E1 model supports an optional 1+1 protection, an optional 10/100 BaseT Ethernet port, an optional V.35, X.21, RS449/V.36, RS232/V.28, or EIA530 or EIA530(A) with DTE/DCE selection.

It is available in two versions:

  • SNMP manageable
  • non-manageable

The SNMP manageable model has a master unit with a CPU for managing a slave unit, and a slave unit without a CPU that is managed by the master unit through EOC. A basic non-manageable model without a CPU provides system setup and loopback by DIP switches setting. Applications include interconnections for LAN, WAN, SONET/SDH, ATM, and DLC.

The T1 model is a basic non-manageable model without CPU. DIP switches are used for system setup and loopback settings. Applications include interconnections for ATM and DLC.
