Fiber Optic Multiplexers FMUX/1U-P (Gigabit Ethernet)

Specifications
Documentation

FMUX/S-xE1/GE Features
  • Point-to-point operation mode.
  • Single or dual (active + protect) optical line operation mode.
  • 1+1 APS (Automatic Protection Switching). Available in dual line operation mode. Data sent on both active and protect lines simultaneously. Automatic failover switching between two lines on receive supported. Switching time is within 50 ms.
  • SFP (Small Form-factor Pluggable) optical transceivers, hot-pluggable.
  • Both single and dual fiber transceivers available.
  • ALS (Automatic Laser Shutdown). Prevents the eyes of operator from being damaged by the laser when the optical transceiver is without fiber. Extends laser life time.
  • RPD (Remote Power down Detection). Helps to distinguish the cause of loss of input signal between fiber broken and remote device powered off.
  • Transmits 8 or 16 G.703/E1 ports data.
  • Transmits one Gigabit Ethernet (10/100/1000BaseT) port data.
  • Transparent and independent transmission of the signal of each data port. The clock signal for each port is unique.
  • Compliance to ITU-T G.703, G.742, G.823 recommendations and IEEE 802.3 standard.
  • Local and remote loopbacks for trouble shooting.
  • Integrated optical line tester. Uses PRBS (pseudo random bit sequence) generator.
  • Console port (RS-232) for device management. Any ANSI terminal or emulation program may be used.
  • Network access to console dialogue through the TELNET protocol (using maintenance Ethernet port, «ETH CONTROL») available.
  • Auxiliary RS-232 asynchronous serial user data port for up to 38.4 kbps transmission.
  • EOW (Engineering Order Wire) option. Standard telephone sets supported.
  • Remote device management supported. Includes remote tributary E1 port loop control and remote device login from the console of local device.
  • SNMP access to the device (using maintenance Ethernet port, «ETH CONTROL») available. Can be used to monitor operational state of the device (including the state of the optical link, E1 ports and Gigabit Ethernet port).
  • LED indicators for optical transceivers and data ports state, loops and test mode indication.
  • 1U construction for 19 inch rack.
  • Power source: 220 VAC ± 10 % and/or 36 to 72 VDC. 1+1 power protection supported if ordered with two power supply units.
  • Firmware may be updated by network.
  • Certificate N ОС-2-СП-1458 of Russian Ministry of Communications

Pair of FMUX/1U-P devices with Gigabit Ethernet ports support transmission of 8 or 16 E1 channels and one Ethernet 10/100/1000BaseT channel over fiber optic link.

In dual line operation (for both single and dual fiber lines) 1+1 automatic failover switching between two lines on receive is supported.

1+1 power protection supported if ordered with two power supply units (220 VAC and/or 36 to 72 VDC).

Device maintenance is achieved by the console (the ANSI terminal connected to the device through the RS-232 interface) or by network by TELNET protocol. SNMP maintenance is also supported.

All ports (E1 and Gigabit Ethernet) transmission over the fiber link is transparent. All E1 channels have independent sync signals with their own unique frequencies.

There are LED indicators for optical transceivers and data ports state, loops and test mode indication located on front panel of the device.

Integrated optical line tester is console controlled. Uses pseudo random bit sequence generator for fiber link testing.

Remote device management is available by remote login feature. Service data exchange is supported by additional service channel using same optical link.

Device firmware may be updated by network.

Shown below is a typical application example:

Typical application example

In the example above E1 ports and the Gigabit Ethernet port (connector «ETH DATA») transfer independently through the fiber optic link. The max link length depends on type of SFP transceivers and fibers used. Both single and double fiber transceivers may be used. If one of transceivers fails to receive input signal then automatic failover switching to receive signal from another line will be performed (this feature may be disabled by configuration). In the drawing above the FMUX (1) device is equipped with the console terminal. To control the FMUX (2) and to monitor its state the remote login to the second device from the console of the first device may be used. TELNET and SNMP access to both devices supported if LAN is connected to them (through «ETH CONTROL» connectors). The EOW feature (optional) may be usable for maintenance personnel. Standard telephone sets (connected to «PHONE» connectors) may be used for voice communication between user premises, where these devices are located. There is the ability to transfer the RS-232 terminal data through the link; in the example discussed the auxiliary terminal connected to the FMUX (1) device auxiliary port (RS-232 connector) is used to control the PBX connected to the auxiliary port (RS-232 connector) of the FMUX (2) device.
