10+Gbps 0.5mm pitch Stacking Connectors
FX10 Series Electrical Interface for the OIF 100G Long-Haul DWDM Transmission Module (MSA-100GLH)
●Mechanical Features
● 0.5mm Pitch
● Stacking Height : 4 ~ 8mm
● Number of Contacts
With ground plate type : 80 / 100 / 120 / 140
Without ground plate type : 96 / 120 / 144 / 168
● Improved Transmission Efficiency
Between Boards
Transmission characteristics have been improved through a
design that fixes ground plates to both sides of the header
and receptacle.
●With GND Plate Type
● 10 Signal:1 Ground Arrangement
Signal and ground are arranged in a ratio of 10:1 with the
ground plate SMT connected to the board. The ground
stability achieved serves to reduce noise.

● Metal Fittings for Added Solder Weld
Signal contact
Strength
Metal fittings provide greater adhesion to the board,
protecting against peeling. The unique connector design
provides a connection between the fitting and the ground
plate for a stronger ground.

● Suited to High-Density Applications
The signal contact pitch of 0.5 mm produces a smaller
connector utilizing less board area for mounting.
●Cut Section
● High contact reliability
Effective mating length is 1.1 mm for signal contacts.
● Optional Ground Plate
An alternate style without the ground plate is available. The
space provided by the ground plate removal has been filled
with additional signal contacts.

●Insertion-Loss-to-Crosstalk-Ratio(ICR)
The insertion-loss-to-crosstalk-ratio (ICR) with five-
aggressor differential FEXT meets the extrapolated
+
IEEE 802.3ap specification for 10 Gbps.
●Differential Impedance
The differential impedance is within 100 +/- 10 ohms
at 30ps rise time (20% to 80%).
