EIG System Components

Undersea Equipment

Optical Fiber

Optical fibers provide the transmission paths for the system. These are high-strength, low-loss fibers designed to meet both mechanical and optical requirements for cable manufacture and in-service system performance.

The following types of optical fiber are used in the Tyco Telecommunications provided undersea and LXE-RL land cable of the EIG cable system:

Large Mode Fiber (LMF) Pure Silica Core (PSC) Z-Type Fiber (used for Segment S4.10) Dispersion Flattened Fiber (DFF) P-Type Fiber

EIG CableTyco Telecommunications SL17 Cable SL17 cable provides an optical path for undersea digitalTransmission, Command Channel and LMS signals.

It also provides a power path for the optical amplifiers.

The following types of SL17 undersea cable are installed in the EIG Submarine Cable System:

LightweightSpecial application (SPA) light-wire armored (LWA) single-armored (SA) double-armored (DA)

SL21 SPA cable is used in the trunk cable of BU4D (Segment 4.9)

Lightweight (LW) cable is the core cable for SL17 cable. The other cable types are produced by adding layers of protection.

EIG CableLand CableLand cable is the part of the undersea cable system that provides optical and

electrical connectivity between the beach manhole and the cable station.

Two types of land cable are used

LXE-RL -- Lightguide Express Entry rodent- and lightning-protected cable Provides optical fiber connectivity Prevents bite damage from field rodents. Shielded to provide protection from lightning. Contains same type and quality of optical fibers used in the undersea cable to which it is

joined. Designed for easy installation in cable-station conduits.

High-voltage (HV) cable provides metal conductor continuity needed to power the undersea repeaters Also used for connecting to the ocean ground bed and for accommodating electroding for

cable tracking and fault locating.

EIG undersea components

REPEATERS Repeaters are placed periodically in the undersea cable to compensate for the optical loss of the cabled fiber paths. Optical amplification is obtained with erbium-doped fiber (EDF) pumped by lasers operating at 980 nm. The repeaters also contain circuitry for optical monitoring and electrical power distribution to the optical amplifiers from the current supplied over the metallic conductor of the cable.

All repeaters in EIG are provided by NEC.

GAIN EQUALIZERS The gain shape and noise of Erbium-doped amplifiers in optical repeaters and the loss of cabled glass fibers are not constant over the wavelength band used by dense wavelength division multiplexed (DWDM) systems. Gain equalization in the undersea system is needed to ensure the proper transmission performance on all the channel wavelengths. Equalization is accomplished using passive optical filters at various locations in the undersea system. These passive optical filters have loss-versus-wavelength shapes designed to work together to achieve a desired net gain-versus-wavelength shape for each end-to-end optical path in the system. A single Gain Flattening Filter (GFF) is located in each repater.Gain equalizer tilt filters (GETs) are located in a specially designed cable-to-cable splice box, referred to a gain equalizer joint-tilt (GEJ-T). Shape compensation filters (SCFs) are located, one per fiber path, in a specially designed cable-to-cable splice box, referred to a gain equalizer joint-shape (GEJ-S). Predetermined wavelength filters (PWFs), are optically spliced and secured in qualified undersea plant GEJ housings

EIG undersea componentsBRANCHING UNITS

The BU provides controllable electrical connections among the three cables and the seagroundelectrode. The electrical connectivity within the BU is controlled using an optical signal. Once a particular state is established, that state is held as long as a minimum holding current is maintained through at least one cable. BU power switching enables full or partial recovery in the event of cable faults.

The power state of Type-34A and Type-34B BUs is controlled by optical steering from thecommand channel equipment (CCE) in the terminal stations. For EIG, the BUs will be controlled at least from two cable stations. The CCE is a self-contained circuit pack that uses the same wavelength as the LME to issue commands to the power switched branching units (PSBUs).

All the BUs are oriented such that all trunks are facing Mumbai.

Terminal Station EquipmentThe LTE for the EIG Cable System consists of the following components:

10-Gb/s high performance optical equipment (HPOE) supports bidirectional transmission of the client signal(s) by providing the processing necessary for transmission of those signals to and from the undersea system as one DWDMwavelength. The HPOE supports both directions of transmission for one wavelength for one end of a transmission path. The functions which it provides include the generation of the wavelengths necessary for DWDM transmission, modulation and demodulation suitable for long-haul transmission, forward error correction (both encoding and decoding), transmit signal adjustments, and transmission performance monitoring. The HPOE provides several optional interfaces to customer equipment.Wavelength termination equipment (WTE) combines individual wavelengths from the transmit portions of multiple HPOEs into a DWDM stream. In the receive direction the WTE separates the incoming DWDM stream from the undersea fiber into individual wavelengths for delivery to the receive portions of individual HPOEs for each wavelength.Terminal line amplifiers (TLAs) are provided where optical gain is required to compensate for component loss or to provide specific optical power levels at certain points within the LTE. Typical LTE configurations utilize a TLA to drive the underseatransmission fiber on the transmit side and to amplify the incoming DWDM signal on the receive side. Some LTE configurations require TLAs at other points within the WTE to compensate for additional optical component loss. MPB enhancement equipment at each station is managed by the MPB element management system (EMS). Transmit booster power amplifiers manufactured by MPB Communications are included in the Segment S4.10 design. These power amplifiers work in conjunction with Tyco SLTE and have maximum saturated optical power up to 30 dBm.

Terminal Station Equipment

Initial Loading Equipment (ILE)

The ILE provides channel power management for systems loaded with less than full system design capacity. For the FP providing service between Egypt South and Mumbai, the ILE is employed for the implementation of initial capacity. The technique of simple noise loading is employed for the implementation of initial capacity in Jeddah.

Command Channel Equipment (CCE)

The CCE is a network element (NE) that serves in the command channel path originatingat the Tyco Element Management System (TEMS) and terminating undersea at theType-34A BU and the Type-34B BU.

The CCE is a self-contained circuit pack that uses the same wavelength as the line monitoring equipment (LME) to issue commands to the Type-34A and Type-34B branching units. The branching units include redundant controllers that receive and decode the CCE commands. The supplied CCEs allow either PSBU to be controlled from at least two cable stations. The association of CCE to FP to PSBU controller is shown in the next slide.

EIG Line Monitoring System (LMS)The LMS comprises all of the undersea and terminal equipment for the detection, location, and reporting of faults in the undersea equipment. It consists of:

● Gen3 LME Circuit PackA self-contained circuit pack which resides in the Common Shelf. Supports the monitoring of eight fiber pairsProvides an optical time-domain reflectometer (OTDR) function to locate optical faults along the length of a repeater span.

● High-Loss Loopback CouplersLoopback coupler modules (LCMs) provide optically passive, wavelength-selective HLLB and broadband optical time-domain reflectometry (OTDR) paths between amplifier pairs in the repeaters.

● LMS Software The Gen3 LME is managed by the TEMS including dedicated LMS graphical user interfaces (GUIs).

EIG Element Management System (EMS)

The EMS for the EIG Cable Network is the Tyco Element Management System (TEMS).

For EIG, the TEMS consists of an operations support processor (OSP) server collocated with the NEs in the cable stations. In addition, TEMS client workstations, software, other peripherals, and elements of local area network (LAN) and wide area network (WAN) equipment are provided at each of the cable stations.

TEMS ClientWorkstation

EIG Element Management System (EMS)

In addition to the NE monitoring function, the TEMS complex of OSPs, along with theTEMS client workstations, provides capabilities for surveillance and fault localization ofthe cable system. When connected to the LME, the TEMS provides similar maintenanceand surveillance capabilities for the undersea equipment.

OSPs also provide database support for data storage and support external interfaces,such as a common object request broker architecture (CORBA) northbound interface(NBI) to a network management system.

TEMS and DCN are deployed across EIG cable stations. A new TEMS OSP is providedin Zafarana, Mumbai, Djibouti, Blue City, Jeddah, and Fujairah along with a TEMS clientworkstation.

EIG Network Management System (NMS) The TEMS-NMS is part of the Tyco Element Management System (TEMS) family of software products. Its main purpose is to provide an integrated network view of TEMS-managed resources at the network management layer (NML). TEMS-NMS offers users a cable-system-wide common interface to undersea trails, fault management (including root cause analysis), and performance management, as well as cut-through access to network element (NE) management via TEMS.

EIG DCN Configuration

Data Communications Network

The Data Communications Network (DCN) is a local area network (LAN)/WAN that provides the backbone connection that links the different network management functions. The DCN for EIG provides voice and data services among all network locations. The DCN consists of routers and Ethernet switches. Figure 1-12 shows the proposed EIG DCN high-level architecture. The as-built DCN configuration is subject to change.

Each Gen3 HPOE provides a user channel implemented as part of the forward error correction (FEC) encoding and decoding on the HPOE circuit pack. The user channel provides an Ethernet 10-Base-T link between the local and the far-end station. The bandwidth necessary to provide this communications channel is allocated in the FEC overhead.

Each user channel connects to a router port in the cable station. The routers in different cable stations are then able to communicate with each other through the overhead channels just as though they were connected together with a crossover cable. The routers in each station are connected to IP switches that in turn connect to all the TEMS and networking (DCN) equipment.

Unity System SynchronizationA Symmetricom SyncServer S200 NTP rack mount time server provides timing for TEMS/NMS/DCN. Tyco supplies and installs the synchronization equipment.

The S200 GPS Network Time Server synchronizes clocks on servers for accurate timing synchronization among every NE and TEMS OSP in the network. The S200 provides reliable and secure network synchronization technology by combining multi-port, high-speed and high-capacity network interfaces and versatile GPS timing receiver technology.

The Stratum 1 level S200 derives its time directly from the atomic clocks aboard the GPS satellite system. By using the integrated, 12-channel GPS receiver, visible satellites can be tracked and used to maintain accurate and reliable time. If the GPS reference is ever lost, the S200 can automatically revert to a Stratum 2 mode and retrieve time from other user-designated time servers

It is the Purchaser's responsibility to define a synchronization plan for the SDH network transported over the Tyco DWDM facility.
