Fiber Optic Phone Multiplexer

Source: Lascomm
The LM8800 is a 4 to 24 Channel Phone Fiber Optic Multiplexer that converts 2-wire FXS (foreign exchange subscriber) to fiber optics on the telephone side
Features:
  • Up to 24 Telephone Lines
  • PBX and Key System Compatible
  • Built-in Dry Contact Relay
  • Multimode or Single Mode (850/1300/1550nm)
  • Built-in Power Redundancy
  • Optical Redundancy (optional)
  • Rackmount or Stand Alone

    Applications
    The LM8800 is frequently used to link/extend telephone lines between two buildings. It is also used in harsh environments where ground loops, EMI/RFI interference and lightning conditions may occur.

    Description
    The LM8800 is a 4 to 24 Channel Phone Fiber Optic Multiplexer that converts 2-wire FXS (foreign exchange subscriber) to fiber optics on the telephone side with ring down capability and FXO (foreign exchange office) on the PBX side. It is divided into increments of four channels per card, up to a maximum of 24 channels (six cards).
    Since the LM8800 digitizes the analog signals (PCM), voice quality does not degrade over extended distances. Distances up to 30km* are typical over single mode fiber, 4km over multimode fiber.

    Diagnostics LEDs for each channel includes Tx, Rx, FXO, FXS, Ring, VccA, VccB, PWR A and PWR B. Power redundancy is standard, optical redundancy is optional. Fiber optic connectors are ST or FC, Electrical connectors are RJ-11. Power is 12VDC, 24VDC, -48VDC or 115/230VAC with an external power cube.

    The LM8800 is available standalone or rack mount. Standalone versions support up to 12 channels, rack mount versions support up to 24 channels. RJ-11 F ports are provided on the rear side to connect with telephones.

    The LM8800 is based on modern FPGA (field programmable gate array) technology. As a result, it benefits users by enabling optimum flexibility, low current consumption, high reliability and maximum MTBFs.
