Terabeam InGaAs APD receivers on eBay

[Phil Hobbs]

I just bought 31 pieces of an InGaAs APD photoreceiver part, made by
Perkin Elmer for Terabeam (a dotcom sort-of-survivor that was going to
transmit data via 1550 lasers through skyscraper windows).

They have SF11 hemispherical lenses on them, but I haven't taken one
apart to see what's inside exactly. They came with the test data.
Price: 75 cents apiece--probably 0.2 cents on the dollar. If they're
like other PE parts, they're probably 0.2 mm diameter. The rated
bandwidth is 100 MHz.

There are some more on eBay again today from the same vendor, so if
anybody wants some to play with, there's an opportunity.

Cheers

Phil Hobbs
