ERA1401 series APD ROSAs are designed for 10 Gbit/s LR-2 and DWDM
applications. This APD ROSA offers high gain and high sensitivity
performance in various optical interfaces: LC/SC receptacles and
an SM fiber pigtails. They can be used in multiple platforms: XFP,
X2, Xenpak, 300pin MSA transponders and line cards.
ERA1402HT series is a fiber pigtail version ROSA with a linear TIA that is designed for a DWDM application.
ERA1401 and ERA1402 series APD ROSAs are made of a high performance APD chip and 3.3V low-noise InP HBT TIA.
