APPLICATIONS
IEEE 802.3aq-2006
10 Gb/s Ethernet transmission on
legacy multimode fiber.
The Finisar FTLX1341E2 transponder incorporates Electronic Dispersion Compensation (EDC)
which provides correction for the severe modal dispersion that may occur during propagation
through links up to 220m on legacy installed FDDI multimode fiber. The EDC device
incorporates a Feed Forward Equalizer (FFE) and a Decision Feedback Equalizer (DFE). The
EDC also contains sophisticated clock recovery architecture for extracting a robust clock from
extremely distorted signals.
PRODUCT SELECTION
FTLX1341E2
* Maximum reach as defined by IEEE. Longer reach possible depending upon link implementation.

Fibers and Connectors
The transponder has SC receptacles for both Tx and Rx. The transponder is designed for multimode
SC cables, 0° polished endface (PC).
70-pin Connector
The module interface connector is a 70-pin, printed circuit board edge connection with a 0.5 mm
pitch. The appropriate mating connector for the customer PCB is a 70-pin SMT, dual row, right
angled, edge connector, 0.5 mm pitch (Tyco Electronics part number 1367337-1, Molex part number
74441-0003 or equivalent).
Rail Requirement
The X2 rail system required to mount the X2 module is fully defined by the MSA.
(Tyco Electronics part number 1367608-1: designed for belly to belly applications;
and 1367610-1, designed for single sided board mount to fit into the standard host PCB
footprint; or equivalent). For further details please refer to vendor-supplied information.
Aqueous Wash
Finisar X2 transponders are neither solderable nor aqueous washable and are not
intended for these processes.
