Chapter 2 Cards Specifications
2.1 Card Overview
TXPP_MR_2.5G 15454-MRP-L1-xx.x= The 2.5 Gbps Multirate Transponder-Protected-100 GHz-Tunable
xx.xxxx. xx (TXPP_MR_2.5G) card has three sets of ports located on
the faceplate and can be installed in Slots 1 to 6 and Slots 12 to 17. It
processes one 8 Mbps to 2.488 Gbps signal (client side) into two 8
Mbps to 2.5 Gbps, 100-GHz DWDM signals (trunk side). It provides
two long-reach STM-16/OC-48 ports per card, compliant with ITU-T
G.707, ITU-T G.957, and Telcordia GR-253-CORE. Each version of
this card has a different part number.
The TXPP_MR_2.5G card is tunable over four wavelengths in the
1550 nm ITU 100-GHz range. The card is available in eight versions,
covering thirty-two different wavelengths in the 1550 nm range. The
TXPP_MR_2.5G card support 2R and 3R modes of operation where
the client signal is mapped into a ITU-T G.709 frame.
MXP_2.5G_10G 15454-10M-L1-xx.x= The 2.5 Gbps-10 Gbps Muxponder-100 GHz-Tunable xx.xx-xx.xx
(MXP_2.5G_10G) card has9 sets of ports located onthe faceplate and
can be installed in Slots 1 to 6 and Slots 12 to 17. It
multiplexes/demultiplexes four 2.5-Gbps signals (client side) into one
10-Gbps, 100-GHz DWDM signal (trunk side). It provides one
extended long-range STM-64/OC-192 port per card on the trunk side
(compliant with ITU-T G.707, ITU-T G.709, ITU-T G.957, and
Telcordia GR-253-CORE) and four intermediate- or short-range
OC-48/STM-16 ports per card on the client side. The port operates at
9.95328 Gbps over unamplified distances up to 80 km (50 miles) with
different types of fiber such as C-SMF or dispersion compensated
fiber limited by loss and/or dispersion. The port can also operate at
10.70923 Gbps in ITU-T G.709 Digital Wrapper/FEC mode. Each
version of this card has a different part number.
Client ports on the MXP_2.5G_10G card are also interoperable with
OC-1 (STS-1)fiber-optic signals definedin TelcordiaGR-253-CORE.
An OC-1 signal is the equivalent of one DS-3 channel transmitted
across optical fiber. OC-1 is primarily used for trunk interfaces to
phone switches in the United States.
The MXP_2.5G_10G card is tunable over two neighboring
wavelengths in the 1550 nm, ITU 100-GHz range. It is available in
sixteen different versions, covering thirty-two different wavelengths
in the 1550 nm range.
