Overview
The LambdaDriver®
EM2009-FXM/ EM2009-FTXM modules use an applicable across the whole trunk, not just locally. This means that

Trunk lengths can range from a couple of kilometers to hundreds of speed to 10 Mbps speed on the appropriate side.
kilometers.Typical applications include:
SFP-based ports support any Fast Ethernet SFP.
The 4-port models occupy one slot space. The 8-port models occupy
two slot spaces.
1) Point-to-point interconnection of up to 8 LANs, one per port
and fully isolated from one another (unlike with a switching
technology), over one or two fibers.
2) CWDM/DWDM Ring interconnection using up to 8 FE channels/
services per wavelength while allowing the coexistence of
additional services on different wavelengths.
The aggregate trunk speed is 2.5 Gbps (even in the 4-port models) so
that these modules can use regular OC48 SFPs, providing distances
of up to 80 km without power or dispersion compensation. They can
also use CWDM/DWDM SFPs to allow higher service aggregation over
a single fiber or MMX SFP’s for a transport distance of up to 2 km over
Multimode fibers.
Four 4-port models and four 8-port models are currently available:
Each model is identified by two options for the access ports (i.e., For distances greater than 80 km, models with a fixed trunk port can

to 400 km (600 km optional) without the need for DCM’s (Dispersion
