AN-FM-480-4GETH offers reliable transmission of 16xE1 G.703 + 4 x Gigabit Ethernet 10/100/1000 ports. 2 RS-232 channels are available as an option. 1+1 fiber optical uplink, Multimode, Single mode and WDM single fiber versions up to 80 km for your use. 

The BNC model provides unbalanced 75 Ohm coaxial connections while the RJ-45 model provides balanced 120 Ohm connections over twisted pair wiring.

All models are available with either multi-mode or single-mode optical tranceivers and with connectors for SC, ST, or FC. In single mode they are available in up to 80 km versions reach, which will provide the ability to transmit and receive data using only a single optical fiber pair or even 1 fiber, if WDM models are used.

All models can be ordered in 1 + 1 fiber uplink protection, which allows use it in applications, where seamless operation are required when main fiber is taken out of service.

E1 G.703 will support also all protocols sent over it, like SS7 signalling, PRI for PABX interconnection, or it can be successfully used at Base Station backbone development for CDMA, GSM, 3G and other applications where E1 G.703 and Gigabit Ethernet are required to send over the same fiber.

• Provides 16 E1 G.703 tranparent transmission over same fiber, supporting all protocols like SS7, PRI etc;
  
• Provides 1 - 4 10/100/1000 Mbit/s (Gigabit Ethernet) channels, working independently from 16 E1 channel;
• Enginering orderwire - EOW, or hotline feature as an option
• 1+1 fiber optical uplink protection on special request
• Optical port uplink rate is 1.25 Gbit/s, to get full Gigabit speed for Ethernet and 16 E1 channels work independently
