assembly (see Figure 1). The same assembly currently available for use with the TE-206 GbE protection
will be used with the TE-2020. Since the E-GbE module has an MPO connector these splitter/combiner
cables will have to be connected to the MPO-to-LC cables using LC-to-LC bulkheads (4).
Figure 3-54 GigE Protection with 50./50 Splitter/Combiner
The protection groups supported on E-GbE PLM, like SONET OC-n equipment protection, are restricted
ports directly above/below one another (i.e., R1-P1-F1 & R2-P1-F1, R1-P1-F2 & R2-P1-F2, R1-P2-F1 &
R2-P2-F1, R1-P2-F2 & R2-P2-F2). Protected E-GbE ports may provisioned for any/all E-GbE equipped a
TE-2020 node including the Main Shelf and associated OTS2s.
3.11 Point-to-Point 8-Channel Protected DWDM Link
A common application of wavelength division multiplexing is combining multiple single wavelength sig-
nals onto a single fiber for transport between two network locations (e.g. two central offices). This applica-
tion utilizes one or more TE-2020s equipped with DWDM OC-48 or OC-192 ITU PLMs, and two
VLX1010 chassis are at each end. Each VLX1010 chassis is equipped with two DWDM trays: one 8-
Channel Mux, and one 8-Channel Demux.
As shown in Figure 3-55, the 8-Channel DWDM terminal multiplex system consists of two unit types, a
Mux and a Demux. The Mux multiplexes eight DWDM wavelengths and the Demux de-multiplexes the
same eight DWDM wavelengths into/out-of a single ‘common’ port. When deployed back-to-back the
Mux and Demux terminal multiplex devices allow full-duplex transmission of up to eight OC-48/OC-192
R.R4.1NE.ETHP.1 Equipment protection for GbE ports on the E-GbE PLM (all reach versions)
with identical functionality as feature on TE-206
R.R4.1NE.ETHP.2 E-GbE protection utilizes the same external 50/50 optical splitter/combiner
cable assembly originally made available to GbE protection on the TE-206
R.R4.1NE.ETHP.3 E-GbE protection is user provisionable on a per port basis
R.R4.1NE.ETHP.4 E-GbE protection groups are restricted to vertically adjacent port pairs (i.e., R1-
P1-F1 & R2-P1-F1, R1-P1-F2 & R2-P1-F2, R1-P2-F1 & R2-P2-F1, R1-P2-F2
& R2-P2-F2)
