Fiber Transmission Products

N3542 and N3742 series provides the ability to transmit 2 digitally encoded video channels over one optic fiber.

Modular in design, the N3542 and N3742 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 7 1310 2.2
Single-mode 17 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 on SM fiber, and include a 3dB safety factor

3 Range estimates for multimode are based on 1000MHz/km fiber
