Standard transceivers are the simplest way to connect 100G traffic, and a large variety of cables and transceivers are compatible with this. Ethernet switch manufacturers seek to pack as many optical transceiver ports as possible onto their hardware to provide customers with rack or data center connections that are both cost-effective and efficient. This enables them to provide the highest channel count and the lowest cost per bit of traffic. The cisco QSFP28 transceiver is the smallest form factor transceiver that the majority of these switch vendors use. It is the smallest module currently on the market and uses the least amount of power among those that can handle 100G traffic. Another noteworthy fact is that the QSFP28 is physically identical to the QSFP+ frequently used for 40G traffic. As a result, switch manufacturers can boost traffic throughput by a factor of 2.5 without having to change their switches' front panels. cable assembly for QSFP28 The use of cable assemblies not only requires fewer components but also eliminates several issues brought on by unclean connections. 0 to 15 meters of DAC (Direct Attached Cables) and 70 meters of AOC (Active Optical Cables) are available. Comparable performance is offered by AOC cable assemblies, fiber cables, and standalone transceivers. TRANSCEIVERS QSFP28 Short-range cisco QSFP -SR4 transceivers enable communications over multimode fiber of up to 100 meters. Similar to employing AOC cables, this method also allows for the usage of structured cabling. Some of the transceiver's cost reductions are offset by its usage of more expensive non-standard MPO (multi-push-on/pull-off cable) connections. The good news is that the switching supplier will now be able to manage data that stays in the data center and rack. The QSFP28 provides the ideal match for these circumstances. It only becomes a concern when 100G traffic needs to be sent across considerable distances, as is the case when connecting 100G data centers in various places. The size and power are still needlessly large, and frequently unreasonably so, even if a manufacturer opts for the lesser CFP2 or CFP4. Offering CFP DWDM capability for the few connections that require it is one approach, but even then, the increase in power consumption and the reduction in available ports affect the switch's overall cost-effectiveness.
