F-E1T1 T1 or E1 Carrier Signals Over Fiber

The F-E1T1  fiber converters allow extension of a single T1 or E1 RJ45  / RJ48c 100ohms port over multi-mode or single-mode   fiber . The standard interface for fiber optics is the SC/APC connector.  T1 interface can be framed or unframed. The fiber converter is totally transparent to the T1 signal. Applications include extension of smart-jacks over fiber, PBX interconnection or T1/E1 transport .
T1/E1 fiber modem provide synchronous, full duplex, half duplex, or simplex data transmission at 1.544 Mbps (T1) and 2.048 Mbps (E1), at distances up to 120 km with fully transparent operation. This product  supports ANSI T1.403, AT&T TR54016 and AT&T TR62411 T1 standards, and CCITT G.703, G.824, G.955 E1 standards. Several different configurations are offered to accommodate a wide variety of fiber optic needs.
