M2SFP+T Test Module

TECHNICAL SPECIFICATIONS

m2sfp_plus_t

Advanced timing test module for Synchronous Ethernet test applications.

The M2SFP+ is a wire-speed 2-port 10 Gigabit Ethernet test module. Based on Xena’s advanced architecture, the M2SFP+ is a proven solution for testing 10G Ethernet at Layers 2-3. It is available for both the 4U 12-slot XenaBay chassis and the robust transportable 1U XenaCompact chassis.

The M2SFP+ comes complete with Xena’s free XenaManager software - an easy-to-use GUI for handling both routine and advanced test schedules that includes XenaIntegrator, XenaScripting, Xena2544, Xena1564, Xena3918 and Xena2889.

PORT LEVEL FEATURES
Interface category 10G Ethernet
Number of test ports 2 x 10G
Interface options 2 x 10GBASE-SR / LR / ER
Number of transceiver module cages 2 x SFP+
Port statistics 1) Link state, FCS errors, pause frames, ARP/PING, error injections, training packet
All traffic: RX and TX Mbit/s, packets/s, packets, bytes
Traffic w/o test payload: RX and TX Mbit/s, packets/s, packets, bytes
Adjustable Inter Frame Gap (IFG) Configurable from 16 to 56 bytes, default is 20B (12B IFG + 8B preamble)
Transmit line rate adjustment Ability to adjust the effective line rate by forcing idle gaps equivalent to -1000 ppm (increments of 10 ppm)
Transmit line clock adjustment From -400 to 400 ppm in steps of 0.001 ppm (shared across all ports)

IGMPv2 multicast join/leave) IGMPv2 continuous multicast join, with configurable repeat interval
Oscillator characteristics • Initial Accuracy is 3 ppm
• Frequency drift over 1st year: +/- 3 ppm (over 15 years: +/- 15 ppm)
• Temperature Stability: +/- 20 ppm (Total Stability is +/- 35 ppm)

ADVANCED TIMING FEATURES*
Selectable Tx line rate Tx line rate can be referenced to either local clock oscillator (adjustable in steps of 1 ppm), SMA input, or from the Rx line rate for Synchronous Ethernet applications. The Tx line rate complies with SONET/SDH/SyncE with respect to wander and jitter.
Jitter attenuation Selectable loop bandwidth for jitter attenuation: 114 Hz, 229 Hz, 460 Hz, 1864 Hz, or 7834 Hz loop bandwidth
SMA input • 10.0 MHz, or 2.048 MHz Tx line rate reference clock SMA input (Drift/wander is passed from SMA input to Tx line rate)
• 250mV-2.5V, loaded 50 ohm
SMA output • Selectable as either Tx Line Rate Reference (10 MHz, 2.048 MHz, or 156.25 MHz), a trigger output indicating Ethernet start of frame, slave mode pass-through (SMA output = SMA input), or as the Recovered Rx clock(s)
• 700mV, loaded 50 ohm
(*These advanced timing features are only supported for 1000BASE-X optical SFP transceivers.)

TRANSMIT ENGINE
Number of transmit streams per port 256 (wire-speed) Each stream can generate millions of traffic flows through the use of field modifiers

Stream statistics 1) TX Mbit/s, packets/s, packets, bytes, FCS error, Pause
Bandwidth profiles Burst size and density can be specified. Uniform and bursty bandwidth profile streams can be interleaved
Field modifiers 16-bit header field modifiers with inc, dec, or random mode. Each modifier has configurable bit-mask, repetition, min, max, and step parameters. 5 modifiers per stream.
Packet length controls Fixed, random, butterfly, and incrementing packet length distributions. Packet length from 56 to 16384 bytes
Packet payloads Repeated user specified 1 to 18B pattern, an 8-bit incrementing pattern
Error generation Undersize length (56B min) and oversize length (16384 max.) packet lengths, injection of sequence, misorder, payload integrity, and FCS errors
TX packet header support and RX autodecodes Ethernet, Ethernet II, VLAN, ARP, IPv4, IPv6, UDP, TCP, LLC, SNAP, GTP, ICMP, RTP, RTCP, STP, MPLS, PBB, or fully specified by user
Packet scheduling modes - Normal (stream interleaved mode). Standard scheduling mode, precise rates, minor variation in packet inter-frame gap.
- Strict Uniform. New scheduling mode, with 100% uniform packet inter-frame gap, minor deviation from configured rates
- Sequential packet scheduling (sequential stream scheduling). Streams are scheduled continuously in sequential order, with configurable number of packets per stream

RECEIVE ENGINE
