Cons

• There is no “power over fiber”. As signals in fiber optics are transmitted using light,

there is no way to transfer power over fiber optics and devices such as cameras must be powered

separately.

What are the cable options for CoaXPress-over-Fiber?

One of the most important benefits of CoaXPress-over-Fiber is the wide variety of connectivity options

already available from multiple companies.

The initial connectivity options for CoaXPress-over-Fiber and the Coaxlink QSFP+ at 10 Gbps are SFP+

and QSFP+ (Quad, or four times SFP+) modules.

The advantage of using modules compared to fixed interfaces is that ports can be equipped

with any suitable type of transceiver as required by the application.

What is the maximum cable length with multi-mode fibers?

With a standard 40GBASE-SR4 QSFP+ Optical Transceiver Module and an MTP/MPO multi-mode fiber

cable, the maximum cable length is 150 meters.

This solution is suitable for machine vision applications.

What is the maximum cable length with single-mode fibers?

With a standard 40GBASE-ER4 QSFP+ LC DOM Optical Transceiver Module and an LC-Duplex single-

mode fiber cable,

the maximum cable length is 40 kilometers. This solution is suitable, for example, for video transmission

applications.
