Overview
The Edge Access L357 Series 10/100/1000 Ethernet Service Unit (ESU) converts and extends
Ethernet media between Local Area Networks (LANs) located up to 120 Km apart.
In addition, the L357 offers Quality of Service (QoS) implementation, Ethernet Jumbo Frame

• User port options:
• 10/100/1000BASE-T copper
• 1000BASE-X fiber
• Extension port: SC connector, simplex or duplex; simplex requires a pair of L357s, one at
1310 nm wavelength and the other at 1550 nm wavelength
• Status LEDs:
• STA shows L357 status
• CFG shows configuration and setup status
• SPD and FDX show status for a UTP User port
• LNK/RX and TX pairs for the User and Extension ports show that data is received and
