Introduction

Increased electrical & fiber optic cabling within Data Centers drive client installation and verification demands.

Data Center Operations require tools to test fiber-rich, carrier-neutral environments for redundancy, high performance connectivity and disaster recovery with handheld fiber optic transport tools scaled to their networks up to 400 Gbps. Data Center Operations and technicians struggle to install, verify and troubleshoot client connections and Data Center Interconnects deployed daily in expanding data centers. Data Center Operations require a hand-held, all-in-one tool for testing and troubleshooting electrical cables and fiber optic interconnects between servers, switches and routers at all data rates, using any given interface, located anywhere in the data center.

Electrical and Fiber Optic Cables are used Through Out the Data Center, Different Types for Different Uses.

Data Center Operations teams are responsible for the installation and verification of client cabling and transported services, from cloud applications to streaming content. Electrical Ethernet cabling such as Cat5e, Cat6 & Cat6a can be found in most plants for delivery up to GbE rates for patch panels, horizontal or vertical cable managers.

Fiber Optic is common for most rates >1GbE and can vary in types, connectors and lengths depending on the application. MPO (Multi-fiber Push On) trunk cables can support up to 72 fiber strands, can be housed in one MPO, but expensive in nature and used for short distances. Single mode fibers are used for longer distances (10-40Km) and higher data rates (up to 100Gbps), but are cost sensitive due to the optics required for data transmission. Multimode duplex fiber provides high data rates (up to 10 Gbps) over short to medium distances (up to 300M).

Data Centers incorporate a combination of electrical and fiber optic data connections, both short and long distances, and utilize a variety of connectors depending on the type of network element, performance and speed required to support the client service.

Fiber Optic Client Cable Testing

1. Fiber Optic Connector Inspection – How Clean is the Fiber Connector?

Dirty or damaged fiber optic connectors can greatly affect network performance. Scratches, chips and contamination on fiber optic connector end faces reduce transmission quality and increase errors. A digital Video Inspection Probe can reduce these issues by verifying the condition and cleanliness of connector end faces during the installation phase without analog microscopes. The connector image and detailed PASS/FAIL status should be displayed as defined by IEC 61300-3-35 ensuring quality and consistency from connector to connector, technician to technician.

2. Optic Transceiver Analysis – Are My Pluggable Optic Modules Functioning Correctly?

As data rates increase to 40 and 100 Gbps, pluggable optics become more complex and additional points of failure. The pluggable optic (CFP, CFP2, CFP4, QSFP+, QSFP28, CXP) support MDIO (Management Data Input/Output) information of the optic transceiver. MDIO analysis and testing verifies the performance of the pluggable optic and monitors alarms and errors to isolate issues from the fiber optic cable and connector.

3. Fiber Optic Cable Measurement – What is My Total Loss? How Much Loss at Each Termination?

Scratched or dirty connectors at fiber cable connections, such as patch panels and adapters can be detected as fault locations from the excessive optical reflections to support fault finding and troubleshooting of client fiber optic cable connections. An OTDR measurement displays results as a trace showing the fiber optic cable length, macro-bends, losses and size of reflections, as well as an easy-to-view summary of the analysis results. The technician can set Pass/Fail conditions based on client service agreement value for each event, which are automatically identified within the OTDR trace. If the evaluation settings prescribed in the client agreement are set beforehand, the measured fiber optic cable loss status can be easily distinguished visually at the same time as measurement ends.

Electrical Client Cable Testing

1. RJ45 Electrical Cable Inspection – Verify for Shorts and Breaks Within the Wire Pairs

For an RJ45 electrical cable, the test makes it easy to identify failures on electrical cables like short circuits or breaks of a wire pair. The cable test should also indicate the distance from the instrument to the fault. This gives the technician the confidence in knowing the cable quality and if necessary, the location of any faults within the cable.

Client Service Verification – Will Data Connection Support the Client Service?

Selection of the proper benchmark verification test and location will determine client services through the data connection. Each benchmark test addresses a specific client services, demarcation point or equipment to determine if the Service Level Agreement has been met.

Figure 5: Selection of the proper benchmark verification test and location will determine client services through the data connection

RFC 2544 - IETF standards body test typically used for packet-based network equipment or new lines. This traditional benchmark test is used to test the layer 2 “pipe” throughput, latency and frame loss measurements after the physical layer 1 fiber or Electrical cable has been tested.

Y.1564 - ITU standards body test relatively new to the industry, often used to replace RFC 2544 in the operator end-to-end testing scenario but not for individual switch/router equipment. Y.1564 is a benchmark test used to emulate the “services” purchased by a client to verify the SAC (Service Acceptance Criteria) agreed upon between client and service provider.

RFC 6349 - IETF standard body test recently developed. This benchmark test tests the layer 4 TCP communication within the packet-based transport. This test is focused on the client-to-client communication once physical, transport and network layers are tested. Service Providers and clients use this benchmark test to enable deeper testing into the packet and designed to test end-to-end throughput through a client demarcation point or firewall.

The Anritsu Solution:

The Anritsu MT1000A Network Master™ Pro & MT1100A Network Master™ Flex provides complete electrical/fiber optic cable testing along with industry recognized data throughput benchmark testing. The MT1100A utilizes all 40 & 100 Gbps compliant interfaces, including QSFP+, CFP, CFP2, CFP4, CXP and QSFP28 to measure total performance of the transceiver while the MT1000A OTDR and 1000 Base-T & 10 Gbps interfaces using RJ45 & SFP measures total performance of the cables, connections and client data and displays the results in customized report.

The Anritsu Network Master Series supports an industry-unique Scenario Editor Environment Kit (SEEK). The SEEK application allows users to string multiple tests into a single, one button operation icon on the instrument. Technicians can now perform all client cable tests (connector inspection, cable test, TCP throughput) in a single function without additional guidance or instruments.
