The DLA22 is a powerful and most versatile device designed for a variety of Fibre-Optic Access and Media Conversion applications. It features 2 Fibre ports (SC or others) and 2 TP (RJ45) ports for connection of local stations or LANs. It utilizes FibroLAN's unique and most successful BMD™ (Buffered Media Domain) technology to facilitate unprecedented Fibre Optic distances (up to 150km) independent from the nature of the local networks. It's flexible architecture, enhanced by factory set VLANs allow its deployment as a Media Converter with a redundant link (fast recovery) and single mode to multi mode applications. The DLA22 may also be deployed as an access device in an ADM (add-and-drop) architecture in ring or string topologies. In this mode, as the copper ports are buffered from the F/O ports, the device provides an electrical bypass in case of failure of the local user. The DLA22 is equipped with an internal quality auto-range power supply (-48VDC power supply is optional). The powerful FEF (Far End Fault) mechanism implemented provides true- link indication and alerts user of any failure of both incoming and outgoing links.

The compact yet robust enclosure allows installation as desk-top, shelf-mounted, wallmounted (2 units on one 19" shelf) or directly in a Half 19" rack.

All DLA22 models are available in SNMP inband managed versions (see DSB107).
