14.8.1 TXP_MR_10G Card

High-performance devices on this card can get hot during operation. To remove the card, hold it by

the faceplate and bottom edge. Allow the card to cool before touching any other part of it or before
placing it in an antistatic bag.
Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed

circuitry could constitute an energy hazard.
The 10-Gbps Transponder–100-GHz–Tunable xx.xx-xx.xx card (TXP_MR_10G) processes one
10-Gbps signal (client side) into one 10-Gbps, 100-GHz DWDM signal (trunk side). It provides one
10-Gbps port per card that can be provisioned for an STM64/OC-192 short reach (1310nm) signal,
compliant with ITU-T G.707, G.709, ITU-T G.691, Telcordia GR-253-CORE, or to 10 GE BASE-LR,
compliant to IEEE 802.3
The TXP_MR_10G card is tunable over two neighboring wavelengths in the 1550-nm, ITU 100-GHz
range. It is available in 16 different versions, covering 32 different wavelengths in the 1550-nm range.
ITU-T G.709 specifies a form of FEC that uses a "wrapper" approach. The digital wrapper lets you
Note
transparently take in a signal on the client side, wrap a frame around it and restore it to its original form.
FEC enables longer fiber links because errors caused by the optical signal degrading with distance are
corrected.
The trunk port operates at 9.95328 Gbps (or 10.70923 Gbps with ITU-T G.709 Digital Wrapper/FEC)
and at 10.3125 Gbps (or 11.095 Gbps with ITU-T G.709 Digital Wrapper/FEC) 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.
Because the transponder has no capability to look into the payload and detect circuits, a TXP_MR_10G
Caution
card does not display circuits under card view.
For the TXP_MR_10G card, protection is done using Y-cable protection. Two TXP_MR_10G cards can
be joined in a Y-cable protection group. In Y-cable protection, the client ports of the two cards are joined
by Y-cables. A single incoming Rx client signal is injected into the Rx Y-cable port and is split between
the two TXP_MR_10G cards (connected to the Rx client ports) in the protection group. The transmit
(Tx) client signals from the two protection group TXP_MR_10G cards are connected to the
correspondent ports of the Tx Y-cable. Only the Tx client port of the Active TXP_MR_10G card is
turned on and transmits the signal towards the receiving client equipment. See the
and Muxponder Protection" section on page 14-119
If you create a GCC on either card of the protection group, the trunk (span) port stays permanently
Note
active, regardless of the switch state. When you provision a GCC, you are provisioning unprotected
overhead bytes. The GCC is not protected by the protect group.
