Fiber Transmission Products

N3511 & N3711 series provides the ability to transmit 1 digitally encoded video channel over one optic fiber.

Modular in design, the N3511 & N3711 series can be rack-mounted or used as a stand-alone module. Rack mounting requires the N3910 series subrack. Stand-alone module is accomplished with N3910-1S and can be placed on a desktop or mounted to a wall.

Fiber Type Optical Budget (dB) Wavelength (nm) Range (km)
Multi-mode 12 1310 4.4
Single-mode 20 1310 25
*Higher output lasers available for range over 25km


1. Distance is limited to fiber loss, splices, chromatic dispersion and bandwidth

2. Range estimates are based on 1.0dB/km @ 1310nm on MM fiber,0.35dB/km @ 1310nm and 0.25dB/km @ 1550nm on SM fiber, and include a 3dB safety factor

3. Range estimates for multimode are based on 500MHz/km fiber
