Typically, customers who want to deliver data at 2-Mbps rates between their remotely located equipment have had to rely upon lease-line services provided by a PTT or Telco. Using the Model 1193, however, customers can extend the G.703 signals on their high speed multiplexors or cellular base stations using Singlemode fibre.
The NetLink Model 1193 Singlemode fibre modem is a low-cost alternative to leasing a G.703 service when connecting remote locations. A pair of NetLink 1193s deliver 2.048 Mbps clear channel data across a single strand of Singlemode fibre at distances up to up to 50 km (31 miles)! That’s five times further than distances available over xDSL (see diagram below). For limited-distance applications up to 2.5 km (1.6 miles), we offers its economical Multimode fibre alternative—the NetLink 1186—which also requires only one fibre.
The 1193 provides 120-ohm (RJ-48) and 75-ohm (dual-coax) options for connecting the G.703 interface of a CSU/DSU, multiplexor, or base station. The modem sends AMI- or HDB3-encoded data over single or Multimode fibre to the remote NetLink 1193. SC or FC fibre interface are available. The Model 1193 is also available as a rack card for use in the NetLink 1001 Telco Access 2U rack chassis. The NetLink 1001 rack system provides dual-redundant AC and/or DC power options and includes all the features of the standalone units.
