Features:- Multiplexes four independent T1 or E1 channels from copper links into one fiber link- Supports optional multiplexed 10/100 copper Ethernet port with T1/E1 circuits- Small Form Pluggable (SFP) transceivers or fixed-fiber connectors- Supports multimode, single-mode dual fiber, single-mode single-fiber, in standard and CWDM wavelengths- Locally configurable via DIP-switches- Configurable alarm relay contacts for audio/visual fault notification- Supports local and remote fiber and copper loop-back modes- Commercial (0 to 50º C) and wide (-40 to 60º C) operating temperature ranges- Lifetime Warranty and free 24/7 Technical SupportThe iConverter 4xT1/E1 MUX multiplexs up to four T1/E1s and an optional 10/100 Ethernet onto a fiber optic transport link. The unmanaged T1/E1 Multiplexer provides an easy to use and cost effective multi-service solution.The iConverter 4xT1/E1 MUXes operate in a back-to-back configuration, with one multiplexer at each end of the fiber link. This easy-to-use and cost-effective MUX transports services from legacy TDM equipment across long distances that exceed the reach or capacity of copper. This includes applications such as T1/E1 extension, mobile backhaul and building-to-building PBX connectivity, making it ideal for Enterprise, Telecom and Utility industries.The 4xT1/E1 MUX supports fixed-fiber and Small Form Pluggable (SFP) transceivers, enabling easy adaptability to different fiber types, distances and wavelengths. The 4xT1/E1 MUX supports multimode, single-mode, single-mode single-fiber, in standard and CWDM wavelengths.The 4xT1/E1 MUX supports standard T1, E1 and Primary Rate Interface (PRI), voice or data. The MUX also supports AMI, B8ZS and HDB3 line codes. DIP-switches provide easy configuration of the T1/E1 line codes and line build-out.The copper interfaces feature four RJ-48 connectors for balanced T1/E1 applications. An optional adapter cable is available to convert each RJ-48 interface to a BNC interface for unbalanced E1 transport applications.The 4xT1/E1 MUX features user-selectable local loop-back on both the copper and fiber ports, remote fiber loop-back and circuit test modes. This functionality facilitates diagnosis of the remote unit, and minimizes the need for test equipment and support personnel at each end of a link. Alarm relay and LEDs provide fault notification for loss of power, LOS and AIS.The 4xT1/E1 MUX is a compact, unmanaged standalone unit available in both AC and DC models. The AC model accepts AC power input ranging from 100VAC to 240VAC, 50/60Hz, while the DC model accepts 18VDC to 60VDC.
