I reached out to several suppliers about the MMA4Z00-NS optical module, but their delivery times were way too long and didn't meet our testing project requirements. Eventually, I placed an order with FS, and now I've received the shipment.

There are very few factories that can provide this product, and I found FS on Google. They have a substantial inventory and offer fast shipping. The packaging was excellent, and the product arrived without any damage. It's been great.

Installation and usage of 2FR4 modules are very convenient. They can be easily matched with our existing single-mode patch cords without the need to purchase additional accessory products.

This product can be connected to my 800G switch, which is very convenient and meets the requirements for short-distance transmission.

The performance of the 800G optical module has surpassed our expectations. It has been running for one week without any issues discovered so far.
