Txp_Mr_10E_C And Txp_Mr_10E_L Cards - Cisco ONS 15454 DWDM Reference Manual

8.5 TXP_MR_10E_C and TXP_MR_10E_L Cards

8.5 TXP_MR_10E_C and TXP_MR_10E_L Cards
The TXP_MR_10E_C and TXP_MR_10E_L cards are multirate transponders for the ONS 15454
platform. The cards are fully backward compatible with the TXP_MR_10G and TXP_MR_10E cards.
They processes one 10-Gbps signal (client side) into one 10-Gbps, 100-GHz DWDM signal (trunk side).
The TXP_MR_10E_C is tunable over the entire set of C-band wavelength channels (82 channels spaced
at 50 GHz on the ITU grid). The TXP_MR_10E_L is tunable over the entire set of L-band wavelength
channels (80 channels spaced at 50 GHz on the ITU grid) and is particularly well suited for use in
networks that employ DS fiber or SMF-28 single-mode fiber.
The advantage of these cards over previous versions (TXP_MR_10G and TXP_MR_10E) is that there is
only one version of each card (one C-band version and one L-band version) instead of several versions
needed to cover each band.
You can install TXP_MR_10E_C and TXP_MR_10E_L cards in Slots 1 to 6 and 12 to 17 and provision
the cards in a linear configuration, BLSR/MS-SPRing, path protection/SNCP, or a regenerator. The cards
can be used in the middle of BLSR/MS-SPRing or 1+1 spans when the cards are configured for
transparent termination mode.
The TXP_MR_10E_C and TXP_MR_10E_L cards feature a universal transponder 2 (UT2) 1550-nm
tunable laser (C band) or a UT2 1580-nm tunable laser (L band) for the trunk port and a separately
orderable ONS-XC-10G-S1 1310-nm or ONS-XC-10G-L2 1550-nm laser XFP module for the client
port.
When the ONS-XC-10G-L2 XFP is installed, the TXP_MR_10E_C or TXP_MR_10E-L card is required
Note
to be installed in a high-speed slot (slot 6, 7, 12, or 13)
On its faceplate, the TXP_MR_10E_C and TXP_MR_10E_L cards contain two transmit and receive
connector pairs, one for the trunk port and one for the client port. Each connector pair is labeled.

A tri-rate client interface (available through the ONS-XC-10G-S1 XFP, ordered separately):
– OC-192 (SR1)
– 10GE (10GBASE-LR)
10G-FC (1200-SM-LL-L)
–
A UT2 module tunable through the entire C band (TXP_MR_10E_C card) or L band
(TXP_MR_10E_L card). The channels are spaced at 50 GHz on the ITU grid.
OC-192 to ITU-T G.709 OTU2 provisionable synchronous and asynchronous mapping.
The MTU setting is used to display the OverSizePkts counters on the receiving trunk and client port
interfaces. Traffic of frame sizes up to 65535 bytes pass without any packet drops, from the client
port to the trunk port and vice versa irrespective of the MTU setting.
