8e1 To Optical Ethernet Converter

Features

•  Realizing the transparent transmission of Ethernet data via 1 to 8 E1 lines
• Providing 10/100Base-Tx&100Base-Fx interface in compliance with the protocol
• standard IEEE 802.3, providing 2 electronical Ethernet ports and one optical Ethernet port
• supporting the working mode of either full duplex or half-duplex.
• Able to transparently transmit the ultra-long frames (up to 1916 bytes) as defined in IEEE 802.1Q, supporting transparent transmission of VLAN frames.
• Providing an in-built dynamic Ethernet MAC address list (1024 addresses) with filtering function for local data frames.
• 128MBits large capacity cache memory and an in-built SDRAM controller, to adapt to various service requirements.
• E1 interface in compliance with ITU-T G.703, G.704 and G.823, not applicable for signaling time slot.
• E1 Support 75Ω/unbalance impedance or 120Ω/balance for order
• Allowing a clock drift up to 512UI in the transmission system, with significantly enhanced reliability.
• Providing availability detection and automatic troubleshooting for 1 to 8 E lines.
• Supporting E1 interface loop-back function and Ethernet loop-back function.
• Self-contained line alarm indication and output.
• Optional power supply, e.g. AC220V or DC-48V; optional mounting type, e.g. desktop or rack mounted.
• Power consumption:
