PAV Launches new 2E1 and 4E1 FSO Systems for GSM/CDMA Network Infrastructure
Free Space Optics provides a rapidly installed connectivity solution for base stations (BTS) in GSM and CDMA networks where installing fixed line infrastructure presents a major challenge
PAV Data Systems, the leading supplier of Free Space Optics systems (FSO) worldwide, announces the fully digital PAVLight 2E1 FSO system. The PAVLight 2E1 transmits two independently clocked E1 circuits (2.048Mbps) over a single FSO link at distances of up to 4kms, and provides an ideal solution for connecting base stations (BTS) in GSM and CDMA cellular networks where the cost and feasibility of fixed line infrastructure present a major challenge. A single PAVLight 2E1 link can support both and GSM and CDMA traffic, making the system a cost effective and attractive option for operators.
The time and cost to deploy the link is further reduced because no indoor unit (IDU) or multiplexer is required, with the two E1 circuits multiplexed at the link head. The PAVLight 2E1 uses a single 120 Ohm RJ45 interface to transmit and receive both E1 streams along a single low cost Cat 5e UTP cable. A 75 Ohm input option is also available to support installations that require the use of coax cables.
PAV has also announced the PAVLight 4E1, offering double the link capacity. A simple module swap upgrade is available to allow the PAVLight 2E1 to be upgraded in the field to support four E1 channels, without the need for re-alignment. The PAVLight 4E1 offers two 120 Ohm interfaces and only requires two Cat 5e cables to transmit and receive the 4E1 channels.
The PAVLight 2E1 and PAVLight 4E1 are both available in single transmitter (for up to 2km) and three-transmitter (for up to 4km) versions. All systems provide an Alarm Indication Signal (AIS) on the E1 channels to allow detection of LOS (Loss of Signal) on the FSO and E1 channels. As with the current PAVLight system, dry contact alarms can also be connected into the existing alarm system of the GSM/CDMA infrastructure.
PAV offers an extensive range of FSO systems, enabling communications up to 4kms and data rates in excess of 1Gbps. With over 8000 PAV FSO links installed worldwide, from cellular telephony infrastructure to enterprise networks, PAV is the world’s leading supplier of Free Space Optics technology.
