Q: Can an SFP28 port be interconnected with a QSFP28 port?
Yes, it is feasible. Configure the 100G QSFP28 port on your device to operate in 4x25G mode if supported, then insert a 100G module into it. Connect this to the SFP28 port using a 1-to-4 cable.
- For the setup involving modules and jumpers: Utilize a 25G SR module on the 25G end, a 100G SR4 module on the 100G end, and link them with a multimode MTP/MPO to 4xLC harness cable.
- Alternatively, for the branch cable: Employ a 100G to 4x25G breakout AOC/DAC cable for interconnection.
Q: Can a 25G SFP28 port support the use of 10G modules?
A: Most 25G ports on devices are designed to support multiple speeds, including 1G/10G/25G, enabling the utilization of modules with these three different data rates.
Q: What are the maximum transmission distances for 25G DAC and AOC?
A: The maximum transmission distance for DAC is 5 meters, while AOC can reach up to 100 meters.
Q: Is FEC functionality required when using 25G DAC?
A: According to the IEEE 802.3by standard, FEC is not necessary for 25G DAC transmission distances of 1, 2, or 3 meters; however, RS-FEC must be enabled for distances of 5 meters.
Q: What is a 25G dual-rate module?
A: A dual-rate module supports two data rate types. Specifically, a 25G dual-rate module is compatible with both 10G and 25G rates, allowing users to switch between these speeds on supported device ports.
