Questions and Answers about Huawei OSN 1500B and Q2CXL1

Q: I buy a Huawei OSN1500B equipped with Q2CXL1, but there will be 622M service, can I change STM-1 module of Q2CXL1 to STM-4 directly?

A: No, you cannot. Q2CXL1 only supports STM-1 eSFP, cannot support STM-4 eSFP.

Q: Then only I can do is buy a Q2CXL4?
A: Yes, you have to change the board.But I suggest you buy Q5CXLLN, it supports STM-1, STM-4 and STM-16 module.

Q: Huawei OSN 1500B Q5CXLLN is perfect, but is there any price difference?
A: Of course, Q5CXLLN is much more expensive than Q2CXLN,not only because Q5 version is universal for STM-1, STM-4 and STM-16 module, but also Q5 version has higher cross-connect capacity than Q2.

Q: Can you tell me their cross-connect capacity difference, that I can have a better evaluation.
A: Higher order cross-connect capacity of Q2CXLN is 20Gbit/s, Q5CXLLN is 60Gbit/s, threes times than Q2CXLN.
