Low-Speed OTN Muxponder Card – APX-OTN-MXP-1G
Product Overview
The Apex APX-OTN-MXP-200G, APX-OTN-TXP-10G and APX-OTN-MXP-1G are OTN line cards for aggregating and transporting lower-rate services over coherent wavelengths. The APX-OTN-MXP-200G concentrates 40G or 10G services onto a 100G or 200G coherent line, the APX-OTN-TXP-10G provides ten 10G transponder ports, and the APX-OTN-MXP-1G maps sixteen low-speed services onto two OTU2 lines.
All three cards carry in-band management over GCC0/1/2 and support SNC/I and SNC/N protection with OTN electrical-layer protection. The APX-OTN-MXP-1G maps ODU0 and ODU1 services onto two OTU2 lines, which suits low-rate access and service grooming at the network edge.

Available Configurations
APX-OTN-MXP-1G Low-Speed Muxponder
Sixteen low-speed clients up to 2.5G, including STM-1/4/16 and FE/GE, are mapped through ODU0 and ODU1 onto two OTU2 lines with OTN electrical-layer protection.
Applications
Metro Service Aggregation
40G and 10G services are gathered onto 100G and 200G coherent wavelengths for efficient metro transport.
Low-Rate Service Grooming
The low-speed card grooms small STM and Ethernet services onto two OTU2 lines, freeing higher-capacity wavelengths for core traffic.
Carrier and ISP Access Networks
Access and aggregation sites use the cards to bring mixed SDH, Ethernet and OTN services into the transport layer.
Utility and Transport Private Networks
Dedicated private networks use SNC/I and SNC/N protection to keep critical services available across the transport layer.
Compatibility
Interoperable with major optical transport and networking platforms. Client interfaces use standard SFP+, QSFP+ and QSFP28 MSA pluggables, the line side follows ITU-T G.709, and all three cards are managed through the host transport platform.
Frequently Asked Questions
What client services can each card aggregate?
The 200G muxponder takes five 40G or twenty 10G clients, the 10G transponder takes ten 10G clients, and the low-speed muxponder takes sixteen clients up to 2.5G.
Which FEC options apply to each line rate?
The 100G line supports G.709 generic FEC or soft-decision FEC, the 200G line uses soft-decision FEC, and 10G OTU2/2e services use I.4 or I.7 EFEC.
What protection schemes are supported?
The cards support SNC/I and SNC/N protection together with OTN electrical-layer protection for carried services.
Can the cards share a chassis with other OTN cards?
Yes. All three are line cards that fit the same OTN transport platform chassis and management as other service cards.
