The 4×25G-PIN-BOX-LANWDM ROSA is a 4x25Gb/s,
1310nm receiver
optical sub-assembly, for 100G applications, consisting of four
high reliability,
high performance PIN PD ,internalquad TIA and an optical
de-multiplexer.
These elements are packaged in a hermetic, planar package with
an LC receptacle.
The electrical interface is through two flex connects. The
ROSA is intended
for use in QSFP28 modules, serving the 100G BASE-LR4
application for links
up to 10km, per IEEE 802.3ba standard.
