Chapter 16 Card Reference
16.8.6 MXP_MR_2.5G and MXPP_MR_2.5G Cards
The 2.5-Gbps Multirate Muxponder–Protected–100 GHz–Tunable 15xx.xx-15yy.yy (MXPP_MR_2.5G)
card aggregates various client SAN service client inputs (GE, FICON, and Fibre Channel) into one
2.5 Gbps STM-16/OC-48 DWDM signal on the trunk side. It provides two long-reach STM-16/OC-48
ports per card and is compliant with ITU-T G.957 and Telcordia GR-253-CORE.
Because the cards are tunable to one of four adjacent grid channels on a 100-GHz spacing, each card is
available in eight versions, with 15xx.xx representing the first wavelength and 15yy.yy representing the
last wavelength of the four available on the board. In total, 32 DWDM wavelengths are covered in
accordance with the ITU-T 100-GHz grid standard, G.692, and Telcordia GR-2918-CORE, Issue 2. The
card versions along with their corresponding wavelengths are shown in
Table 16-63 .
The muxponders are intended to be used in applications with long DWDM metro or regional
unregenerated spans. Long transmission distances are achieved through the use of flat gain optical
amplifiers.
The client interface supports the following payload types:
•
GE
•
1G FC
•
2G FC
• 1G FICON
•
2G FICON
Note
Because the client payload cannot oversubscribe the trunk, a mix of client signals can be accepted, up to
a maximum limit of 2.5 Gbps.
Table 16-64 shows the input data rate for each client interface, and the encapsulation method. The
current version of the Transparent Generic Framing Procedure (GFP-T) G.7041 supports transparent
mapping of 8B/10B block-coded protocols, including Gigabit Ethernet, Fibre Channel, and FICON.
In addition to the GFP mapping, 1-Gbps traffic on Port 1 or 2 of the high-speed SERDES is mapped to
an STS-24c channel. If two 1-Gbps client signals are present at Port 1 and Port 2 of the high-speed
serializer/deserializer (SERDES), the Port 1 signal is mapped into the first STS-24c channel and the Port
2 signal into the second STS-24c channel. The two channels are then mapped into an OC-48 trunk
channel.
