Can anyone identify this chip? It's supposed to be a 155mbit fiber optic transceiver, but I'm not sure I can read the logo (GZJL?) and "7901" isn't finding anything...

I think it's just ZJL

@marcan can't find the logo here oddly:

The alibaba website also has a picture search engine we can abuse to identify components.

Unfortunately it doesn't work for this one.

No luck with the chip.
The soldering on the optical device looks a bit suss.

@marcan Suzhou Kaipu Microelectronics Co., Ltd. (operated by Gui Zhilong) sell components with a GZJL prefix. lots of clones. they may have also traded as YGWCO for a while.

@gsuberland @marcan GZJL makes a lot of sense from what I can see printed on the picture.

@marcan Wild, I can't find anything for any variation of that manufacturer logo...
