397-O9330 Fiber Optical Mux
Or call us on

The Loop Fiber Optical Mux product line provides practical solutions for interconnections for LAN, WAN, SONET/SDH, asynchronous transfer mode, and digital loop carriers.

The Fiber Optical Mux product family provides ideal solutions for building fiber-based E1/T1 networks. As part of this family, the Loop-O9330 can transparently carry up to 16 channels E1/T1 or 8 channels V.35 DTE, and 100 Mbps Ethernet signals over a single fiber.

All services are transported point-to-point in a real static TDM manner, which includes

  • 16 E1, 16 T1, or 8 V.35
  • 100Mbps Ethernet
  • a management channel

The bandwidth is guaranteed for full configuration of the mentioned speeds for each channel/service.

To select a protection level, users can choose either single pair or dual pair fiber. Either a single power supply or dual power supplies can be chosen.

The Loop-O9330 offers management through console port, Ethernet port, Telnet, and SNMP agents. It supports local control and diagnostics using a 2-line by 16-character LCD display and keypads or console port. The unit also supports local and remote monitoring and diagnostics. Contacts for office alarms are available.

Applications for Loop-O include interconnections for LAN, WAN, SONET/SDH, ATM, and DLC.
