T1/E1/PRI Fiber Products
FiberPlex TD-5402 T1 to Fiber Converter | E1 to Fiber Converter | ISDN PRI Isolator / Modem Rugged Industrial Enclosure

T1 to Fiber Converter | E1 to Fiber Converter | Optical Isolator/Modem. Mission-Critical Packaging. The TD-5400 Series T1/E1 Fiber Extenders isolate, convert, and extend T1/E1/PRI services.

The TD-5401 and TD-5402 T1 to Fiber Converter / E1 to Fiber Converter provides electrical isolation and extension of T1 and E1 signals. These units are ideally suited for T1/E1 trunk or backhaul or for the extension of ISDN Primary BRI, PBX and SATCOM links. Traditional E1 cabling is limited to a maximum distance of 4800 ft (1.46 km), but multimode optics on the unit can extend the distance to 1.2 miles (2 km), while singlemode optics can further extend the distance to 20km.

The unit can be used in areas of high electrical noise or in and out of RF shielded enclosures. The fiber optic cable is not susceptible to interference caused by impulse noise, crosstalk, or EMI. Privacy of communications is also enhanced because the fiber optic cable does not radiate any emissions.

A standard link would consist of one unit at each end of a fiber cable connection. These units create a simple plug and play point to point fiber extension for T1 or E1 circuits which makes deployment of circuit extensions fast and easy. Due to the flexible nature of SFP modules, the SFP version of this unit can accommodate a variety of singlemode, multimode, BiDi or CWDM optical modules providing maximum flexibility.
