CN 4200 uses G6/F10A to
multiplex up to 4 STP
signals per wavelength
Only 4 wavelengths
required, immediate 12λ
savings
Can also mux STP w/
other data links (FICON,
ESCON, FC) for additional
wavelength efficiency

Up to 67% lower
wavelength counts
vs. competitive
solutions
Ciena’s approach electrically multiplexes up to 4 STP/ISC-3p or 8 ISC-2 per wavelength

DBA allows secure, aggregation of
multiple services over the same WAN
Different levels of performance (i.e.

Challenges:
Solution:
Need to rate limit each port to ensure the WAN
router is not overrun
No rate limiting required
Bandwidth per storage array is limited (i.e. 25%
available if 4 storage arrays)
DBA dynamically adjusts bandwidth as needed
Need to complete a detailed assessment of the
IP network to ensure packet loss
Ciena ensure 0% packet loss therefore no
assessment required
GbE interfaces compress, require a
