Q: What types of 25G SFP28 optical modules are there?
A: There are three categories of 25G modules: 25G dual-fiber bidirectional modules (SR, LR, ER), 25G single-fiber bidirectional modules (BiDi), and 25G WDM color optical modules (CWDM, DWDM, LWDM).
Q: What is the maximum transmission distance for 25G SFP28 optical modules?
A: Currently, the SFP-25G-ER model offers the greatest reach, theoretically up to 40 kilometers. It’s possible that future 25G modules may support even longer transmission distances.
Q: Are SFP28 optical modules backward compatible?
A: Yes, they support backward compatibility with 10G rates.
Q: Can an SFP28 port be interconnected with a QSFP28 port?
A: Yes, it’s feasible. If supported, configure the 100G QSFP28 port on your device for 4x25G mode, insert a 100G module into this port, and link it to the SFP28 port using a 1-to-4 cable.
- For the connection, use a 25G SR module on the 25G side, a 100G SR4 module on the 100G side, and a multimode MTP/MPO to 4xLC harness cable in between.
- Alternatively, use a 100G to 4x25G breakout AOC/DAC cable for interconnection.
Q: Can a 25G SFP28 port support the usage of 10G modules?
A: Generally, 25G ports on devices are designed to support multiple rates, including 1G, 10G, and 25G, allowing the use of modules with these different speeds.
Q: What are the maximum transmission distances for 25G DAC and AOC?
A: DACs can reach up to 5 meters, whereas AOCs can extend as far as 100 meters.
