Available in three hardware configurations, each FTB-860x offers the industry’s largest TFT screen with unprecedented configuration simplicity via hybrid touchscreen/keypad navigation. Platform connectivity is abundant via Wi-Fi, Bluetooth, Gigabit Ethernet or USB ports, making it accessible in any environment.FTB-860G: 10 M BIT /S TO 10 G BIT/SIf the need is for full Ethernet coverage from 10 Mbit/s up to 10 Gbit/s, › 10 Base-T to 10 gigabit testing› IPv6 testingFTB-860: GIGABIT ETHERNETIf the need is purely for Gigabit Ethernet coverage, then the FTB-860 is › 10 Base-T to 1 gigabit testing› IPv6 testingFTB-860GL: 10 M BIT/S TO 10 G BIT/S LOOPBACK ONLYCombined with the FTB-860G or FTB-860, the FTB-860GL is the most cost-effective solution for GigE and 10 GigE intelligent loopback testing; it supports bidirectional EtherSAM and RFC 2544 testing and offers five › 10 Base-T to 10 gigabit loopback› EtherSAM (bidirectional partner)*› RFC 2544 (bidirectional partner)› Intelligent autodiscovery› IPv6 testing› Ping/traceroute* Contact your EXFO representative to confirm availability.Setting a New GUI Standard: Unprecedented Simplicity in Configuration Setup and NavigationIntelligent Situational Configuration Setup›G uides technicians through complete, accurate testingprocesses(suggestion prompts, help guides, etc.)›R educes navigation by combining associated testingfunctions on a single screen›I ntelligent autodiscovery allows a single technician to performend-to-end testingDedicated Quick-Action Buttons›Remote discovery to ﬁ nd all the other EXFO units›Laser on/off›T est reset to clear the results and statistics while running a test ›Report generation›Save or load test conﬁ gurations›Quick error injectionAssorted Notifications›Clear indication of link status for single or dual ports›Negotiated speed display for single or dual ports›O ptical power status available at all times for single or dual ports›Pass/fail indication at all times for all testsStreamlined Navigation›R emote discovery button available at all times; no reason to leave your current location to scan for a remote unit›T esting status can be maximized to ﬁ ll the entire screen by simply clicking on the alarm status button; whether the unit is in your hand or across the room, test results can be easily determined with a simple glance at the display screen›R FC 2544 conﬁguration is maximized in a single page;no need to navigate through multiple screens to conﬁindividual subtests›R FC 2544 results and graphs are also maximized in a single page; no need to navigate through multiple screens to viewindividual RFC subtest results FO unitswhile running a testdual portsal portstimes for single mes; no reason toemote unite entire screen by ; whether the unit sults can be easily splay screenn a single page; eens to conﬁ gure ximized in a single e screens to viewRAPID, ACCURATE TEST RESULTS AT YOUR FINGERTIPSKey FeaturesIntelligent Network Discovery ModeUsing any NetBlazer series test set, you can single-handedly scan the network and connect to any available EXFO datacom remote tester. Simply select the unit to be tested and choose whether you want traffic to be looped back via Smart Loopback or Dual Test Set for simultaneous bidirectional EtherSAM and RFC 2544 results. No more need for an additional technician at the far end to relay critical information—the NetBlazer products take care of it all.Smart Loopback FlexibilityThe Smart Loopback functionality has been enhanced to offer five distinct loopback modes. Whether you are looking to pinpoint loopback traffic from a UDP or TCP layer, or all the way down to a completely promiscuous mode (Transparent Loopback mode), NetBlazer has the flexibility to adjust for all unique loopback situations.Global Pass/Fail AnalysisThe NetBlazer series provides real-time pass/fail status via text or icons. Clicking on the pass/fail indicator maximizes this important status to full screen, providing instant, easily understood notification whether the unit is in the technician’s hands or across the room.Remembering the Last IP or MAC AddressesField technicians have enough things to worry about and don’t always have the luxury of time to enter the same IP or MAC address test after test. The NetBlazer series remembers the last 10 MAC, IPv4 and IPv6 addresses as well as J0/J1 traces for 10G WAN, even afterthe unit has been rebooted.Traffic GenerationUnparalleled analog visual gauges combined with user-defined thresholds show instantaneously whether or not the test traffic is in or out of expected ranges.Additionally, bandwidth and frame size can be modified on-the-fly without navigating away to a different page, giving technicians instantaneous reaction on the gauges. Traffic generation brings together over 10 critical stats in a very visual and organizedfashion, ensuring that technicians can quickly and easily interpret the outcome of the test.The analog gauges are lined with Green and Red layers to represent the expected thresholds.Real-time bandwidth and frame-size adjustment.Overall pass/fail assessment.Throughput, jitter and latency with visual pass/fail thresholds,analog gauges and digitalreadouts.Frame loss and out-of-sequence notification.Multistream ConfigurationConfiguring multiple streams with proper COS and QOS bits can be a complex task. NetBlazer makes it simpler, with all streams easily selectable and configurable from one location. With large icons located throughout the stream pages, configuration becomes as simple as a touch of a finger. Technicians can define one configuration profile and apply it to all the background streams simultaneously. From there, it is just a matter of making slight tweaks as needed rather than complete configuration profiles per stream.Through ModeThrough mode testing consists of passing traffic through either of the NetBlazer’s two 100/1000 Base-X ports or the two 10/100/1000 Base-T ports for in-service troubleshooting of live traffic between the carrier/service provider network and the customer network. Through mode allows technicians to access circuits under test without the need for a splitter.Supporting 10 Gigabit EthernetThe 10 G igabit Ethernet interface is available in both 10 G igE LAN and 10 G igE WAN modes via a single SFP+ transceiver. All Ethernet testing applications—from BER testing to the full EtherSAM suite—are available for both IPv4 and IPv6. Unique to the 10 GigE WAN interface is the ability to send and monitor SONET/SDH J0/J1 traces and the path signal label (C2). The WAN interface can also monitor SONET and SDH alarms and errors.E THER SAM: THE NEW STANDARD IN ETHERNET TESTINGUntil now, RFC 2544 has been the most widely used Ethernet testing methodology. However it was designed for network device testing in the lab, not for service testing in the field. ITU-T Y.156sam is the newly introduced draft standard for turning up and troubleshooting carrier Ethernet services. It has a number of advantages over RFC 2544, including validation of critical SLA criteria such as packet jitter and QoS measurements. This methodology is also significantly faster, therefore saving time and resources while optimizing QoS.EXFO’s EtherSAM test suite—based on the draft ITU-T Y.156sam Ethernet service activation methodology—provides comprehensive field testing for mobile backhaul and commercial services.Contrary to other methodologies, EtherSAM supports new multiservice offerings. It can simulate all types of services that will run on the network and simultaneously qualify all key SLA parameters for each of these services. Moreover, it validates the QoS mechanisms provisioned in the network to prioritize the different service types, resulting in better troubleshooting, more accurate validation and much faster deployment. EtherSAM is comprised of two phases, the network configuration test and the service test.Network Configuration TestThe network configuration test consists of sequentially testing each service. It validates that the service is properly provisioned and that all specific KPIs or SLA parameters are met.Service TestOnce the configuration of each individual service is validated, the service test simultaneously validates the quality of all the services over time.EtherSAM Bidirectional ResultsEXFO’s EtherSAM approach proves even more powerful as it executes the complete ITU-T Y.156sam test with bidirectional measurements. Key SLA parameters are measured independently in each test direction, thus providing 100 % first-time-rightservice activation—the highest level of confidence in service testing.EX PERT TEST TOOLSEXpert Test Tools is a series of platform-based software testing tools that enhance the value of the FTB-1 platform, providing additional testing capabilities without the need for additional modules or units.The EXpert VoIP Test Tools generates a voice-over-IP call directly from the test platform to validateperformance during service turn-up and troubleshooting.›Supports a wide range of signaling protocols, including SIP, SCCP, H.248/Megaco and H.323 ›Supports MOS and R-factor quality metrics› Simplifies testing with configurable pass/fail thresholds and RTP metricsThe EXpert IP Test Tools integrates six commonly used datacom test tools into one platform-based application to ensure field technicians are prepared for a wide-range of testing needs. › Rapidly perform debugging sequences with VLAN scan and LAN discovery› Validate end-to-end ping and traceroute› Verify FTP performance and HTTP availabilityTEST TOOLS IPEXpert TEST TOOLS VoIPOPTICAL INTERFACESTwo ports: 100M and GigEAvailable wavelengths (nm)850, 1310 and 1550100 Base-FX100 Base-LX1000 Base-SX1000 Base-LX1000 Base-ZX1000 Base-BX10-D1000 Base-BX10-USFP+ OPTICAL INTERFACES (10G)10G Base-SR/SW10G Base-LR/LW 10G Base-ER/EW Wavelength (nm)85013101550Tx level (dBm)–5 to –1–8 to 0.5–4.7 to 4.0SPECIFICATIONSELECTRICAL INTERFACESTwo ports: 10/100 Base-T half/full duplex, 1000 Base-T full duplexGENERAL SPECIFICATIONSSize (H x W x D)130 mm x 36 mm x 252 mm (5 1/8 in x 1 7/16 in x 9 15/16 in)Weight (with battery) 0.58 kg (1.3 lb)TemperatureTESTINGEtherSAM (Y.156sam)Network configuration and service test as per ITU-T Y.156sam.
