Loop Telecom Fiber Optical Multiplexer 4E1 Ethernet O9310 / Loop-O9310-CPU-4E120-SSS-SD48-G

SKU: 2607 Category:



Loop Telecom's Loop-O Fiber Optical Mux product family provides ideal solutions for building fiber-based E1 or T1 networks. The Loop-O9310 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). It is available in two versions: (1) SNMP manageable and (2) non-manageable. The SNMP manageable model has a master unit with CPU for managing a slave unit, and a slave unit without CPU that is managed by the master unit through EOC. A basic non-manageable model without 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.
