Transponders and Muxponders
The ONS 15454 transponder (TXP) and muxponder (MXP) cards transport SONET, SDH, 2R, and 3R payload data types across a dense wavelength division multiplexing (DWDM) network. The ONS 15454 TXP and MXP cards include:
 •
The ADM-10G card that operates on ONS 15454 MSTP and DWDM networks to transport optical signals and Gigabit Ethernet signals over DWDM wavelengths. In an MSTP network based on Gigabit Ethernet and OC-3, OC-12, OC-48, or OC-192 SONET line cards, the ADM-10G card transports low bit-rate SONET traffic over DWDM by mapping Gigabit Ethernet and SONET circuits to the same wavelength with multiple protection options.
 •
The GE_XP, 10GE_XP, GE_XPE, and 10GE_XPE cards, which are Gigabit Ethernet (GE) Xponders for the ONS 15454 SONET and SDH platforms. The cards aggregate Ethernet packets received on the client ports for transport on 100 GHz grid, C-band, trunk ports with ITU-T G.709 framing and either forward error correction (FEC) or enhanced FEC (E-FEC). The cards are designed for bulk GE point-to-point transport over 10GE WAN PHY wavelengths, Video-on-Demand (VoD), or broadcast video across protected 10GE WAN PHY wavelengths.
 •
The 10-Gbps transponder–100-GHz–tunable (TXP_MR_10E_C and TXP_MR_10E_L) cards, which are multirate transponders for the ONS 15454 platform. On the trunk side, the TXP_MR_10E_C and TXP_MR_10E_L cards provide a 10-Gbps STM-64/OC-192 interface. There are 80 tunable channels available in the 1550-nm C-band or 82 tunable channels available in the 1580-nm L-band on the 50-GHz ITU grid for the DWDM interface. The TXP_MR_10E_C and TXP_MR_10E_C cards provide 3R transponder functionality for this 10-Gbps trunk interface. Therefore, the card is suited for use in long-range amplified systems. The DWDM interface is compliant with ITU-T G.707, ITU-T G.709, and Telcordia GR-253-CORE standards.
 •

 •
The 10-Gbps transponder–100-GHz–tunable xx.xx-xx.xx (TXP_MR_10E), which is a multirate transponder card for the ONS 15454 platform. The card is fully backward compatible with the TXP_MR_10G card. It processes one 10-Gbp signal (client side) into one 10-Gbps, 100-GHz DWDM signal (trunk side) that is tunable on four wavelength channels (ITU-T 100 GHz grid).
 •
The 2.5G Multirate Transponder (TXP_MR_2.5G) card, which processes one 8-Mbps to 2.488-Gbps signal (client side) into one 8-Mbps to 2.5-Gbps, 100-GHz DWDM signal (trunk side). It provides one long-reach OC-48 port per card, compliant with ITU-T G.707, ITU-T G.709, ITU-T G.957, and Telcordia GR-253-CORE.
 •
The 2.5G Multirate Transponder-Protected (TXPP_MR_2.5G) card, which 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 OC-48 ports per card, compliant with ITU-T G.707, ITU-T G.957, and Telcordia GR-253-CORE.
 •
The 2.5-Gbps Multirate Muxponder-Protected–100-GHz–Tunable 15xx.xx-15yy.yy (TXPP_MR_2.5E) card aggregates various Storage Area Network (SAN) service client inputs (ESCON, GE, FICON, and Fibre Channel) into one 2.5 Gbps DWDM signal on the trunk side. It provides two long-reach OC-48 ports per card and is compliant with ITU-T G.957 and Telcordia GR-253-CORE.
 •
The Muxponder 2.5/10-Gbps (MXP_2.5G_10G) card 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 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 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 Muxponder 2.5/10-Gbps (MXP_2.5G_10E) card 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 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 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 2.5-Gbps Multirate Muxponder-100GHz-Tunable 15xx.xx-15yy.yy (MXP_MR_2.5G, MXPP_MR_2.5G, MXP_2.5G_10G, and the MXPP_2.5G_10G) cards aggregate a mix and match of client SAN service client inputs (enterprise system connectivity [ESCON], Gigabit Ethernet [GE], fiber connectivity [FICON], and Fibre Channel) into one 2.5-Gbps DWDM signal on the trunk side. It provides one long-reach OC-48 port per card and is compliant with ITU-T G.957 and Telcordia GR-253-CORE.

The MXP_MR_10DME_L and MXP_MR_10DME_C cards are DWDM muxponders for the ONS 15454 SDH platform that support full optical transparency on the client side.
Note
The muxponders are labeled 10DME-L and 10DME-C on the faceplate.
 •
The 2.5-Gbps–10-Gbps Muxponder–100 GHz–Tunable (MXP_2.5G_10E_C and MXP_2.5G_10E_L) cards, which are DWDM muxponders for the ONS 15454 platform that support full optical transparency on the client side. The cards multiplex four 2.5-Gbps client signals (4 x OC48/STM-16) into a single 10-Gbps DWDM optical signal on the trunk side. The MXP_2.5G_10E_C and MXP_2.5G_10E_L cards provide wavelength transmission service for the four incoming 2.5 Gbps client interfaces. The MXP_2.5G_10E_C and MXP_2.5G_10E_L muxponders pass all SONET/SDH overhead bytes transparently. The MXP_2.5G_10E_C and MXP_2.5G_10E_L cards are not compatible with the MXP_2.5G_10G card, which does not support full optical transparency.
