Viavi TM400GB-QO

Both variants of this module provide dual-port testing and broad support of multiple interface types with a built-in GNSS receiver for future expansion. The test interfaces include QSFP-DD (2 ports on TM400GB-QQ), OSFP on the TM400GB-QO version, and two SFP-DD physical ports. The reporting of full power consumption is available for all optics types. Capabilities feature native PAM4 and NRZ with CMIS and electrical pre-emphasis support. Superior cooling capabilities enable the support of 400GE ZR/ZR+ pluggable optics.  

The 400G Transport Module provides the following Ethernet rates: 400GE, 200GE, 4x100GE, 100GE with no FEC, RS (528,514) FEC or full KP4 RS (544,514) FEC, 50GE on SFP56, 40GE, 25GE (FEC or bypass), 10GE; 1GE and 10/100/1000. It also supports OTU4, OTU3, OTU2e, OTU1e, OTU2, and 64G Fibre Channel and provides a loopback capability to help test AOC (Active Optical Cable) and DAC (Direct Attach Cable) cables for data center applications.   

Vendor package 400G-NOPT (no transceivers included) includes:

Key Features:

• Dual-port testing up to 400GE. For rates up to 200GE, it is possible to reload a port independently without affecting a test running on the other port; this provides any port, any rate, any time 
• Testing using 400GE, 200GE, 100GE and 4x100GE ZR/ ZR+ pluggable modules. Can set the transmitter to different channel/wavelength/ frequency values and optical power levels. Reporting of coherent receiver statistics. Support of grid granularity down  to 3.125GHz. 
• Support of up to 4 VLAN tags 
• Full line rate bandwidth including Ethernet burst testing.  Support of layer 2 and layer 3 IPv4 testing including ARP, DHCP and IPv6. 
• Packet capture and decode 
• Selection of frame sizes up to 16,000 bytes including random distribution and EMIX 
• RS (544,514) FEC testing for correctable errors up to 15 symbols and uncorrectable errors. Monitoring of  high BER rates with a user settable alarm threshold. As applicable, support of RS(528,514) FEC. 
• Support of a 4x100GE application with 4 independent 100GE engines 
• Key Performance Indicator testing using ATPv3 which provides real-time frame loss, out-of-sequence,  latency, and packet jitter measurements 
• Run Ethernet tests with up to 16 parallel streams 
• Bit Error Rate testing using PRBS patterns in Ethernet frames. Multi-lane unframed BERT is available  as an option. 
• Optics Self-Test for QSFP-DD, OSFP, and SFP devices. Includes pre-FEC and post-FEC BER results with  pass/fail results based on BER theory, PPM offset testing, and temperature monitoring 
• Control of QSFP-DD devices and registers via expert mode. This includes pre-emphasis and per register  access and dump to file. Selection of application codes for CMIS pluggables. Support of both CMIS and SFF8636 devices. 
• Ethernet level testing including QuickCheck, RFC 2544, and Y.1564 SAMComplete™ 
• Selection of host interface based on NRZ (100GAUI-4) or PAM4 (100GAUI-2) for 100GE pluggable devices. 
• Cable Test for AOC, DAC, and AEC cables. Support of a QSFP loopback function to test straight and breakout cables with a single module.
