Break-out cable designed for 40GBase-LR4 / ER4 transceivers
14.00
Until today this was done with standard break-out cables for Multi-mode 40GBase transceivers, resulting in a limited reach of only 300 meter. CUBO’s 40GBase-LR4/ER4 Break-Out cable with its integrated 40G CWDM multiplexer inside extends this reach to 10 or 40km for single mode transceivers.
The switches allow the configuration of each 40G switch port to act as four individual 10G ports. However, although the switch port is configured as if it was virtually four pieces of 10G ports, it physically remains one port. This port is typically in accordance with the QSFP+ standard, for which only 40GBase-SR/LR/ER optics exist.
For multimode versions, the transceiver already features 4 duplex fibre in/outputs, so only a cable or connector adaption is required. Single mode versions are based on four different wavelengths streams which are multiplexed, respectively de-multiplexed, into one fibre output / input. Therefore the break out cable cannot simply adapt to different connectors but also must feature the matching optical multiplexer inside the cable to be able to mux and demux the four lambdas from one duplex transceiver port to 4 fibre pairs.
