A: Following the approval of your order, the product will require 1-3 working days for production and preparation. Afterwards, it will be shipped directly from our warehouse to you, and you will receive a notification SMS from us.
Q: What is the maximum transmission distance for a 25G SFP28 transceiver?
A: Presently, the theoretical maximum transmission distance achievable is 40 kilometers.
Q: Does the SFP28 optical module support backward compatibility?
A: Yes, it supports backward compatibility with 10G rates.
Q: Can an SFP28 port interconnect with a QSFP28 port?
A: Yes, they can interconnect. You may use either a module plus jumper or a breakout cable to do so.
- For the module+jumper setup: The 25G side employs a 25G SR module, while the 100G side uses a 100G SR4 module, with a multimode MTP/MPO to 4xLC harness cable connecting them in the middle.
- For the breakout cable: Utilize a 100G to 4x25G breakout AOC/DAC cable for the interconnection.
