Between them lies the Optical Distribution Network (ODN) consisting of fibers and passive splitters or couplers. A splitter is a device that divides an optical signal into two or more signals. It can also reassemble signals from multiple signal sources into one signal. The GPON technology is based on Passive Optical Network (PON) technology. Traditionally, telecommunication networks use devices that require power to transmit data from one point to another including processors, memory chips, repeaters, and relays. With ... -

Description GEM is based on the SONET/SDH Generic Framing Procedure (GFP) for handling time division multiple access (TDMA), ATM and Ethernet based traffic without additional encap‐ sulation protocols. Signal transmission from ONTs to OLT uses a type of TDMA. TDMA is a technique used to frame channels of data. In this technique, data communication sessions originating from multiple points are transmitted in turn. Each data communication session is assigned a time slot in the TDMA frame and transmits (or accesses that time slot) only at that time. In order to allow for the transmission of downstream and upstream traffic on a single fiber, different wavelengths are used for both directions. Downstream traffic uses 1490 nm while upstream traffic uses 1310 nm. The ONT employes diplexers (or triplexers, in the case of TV overlay) to separate wavelengths. Downstream data is broadcast from the OLT to all ONTs. Each ONT processes the data destined to it by matching the address at the protocol transmission unit header. The downstream PON signal is broadcast to up to 32 ONTs with a data rate of 2.5 Gbps for voice and data, plus the additional video overlay wavelength division multiplexing (WDM) signal. In the upstream direction transmission of data must be coordinated between each ONT to avoid collisions due to the shared media of the optical distribution network (ODN). Data is transmitted according to control mechanisms configured in the OLT. The aggregate upstream rate is 1.25 Gbps. Figure 1 illustrates the front of the ONT housing. Figure 1.

Page 27: Determining Ont Enclosure Location
Installation CAUTION • This equipment must be connected to a known, reliable earth ground at all times during installation and service. Refer to the National Electrical Code (NEC) and state/local codes for details on grounding requirements. A 6 AWG copper ground conductor shall be used to connect the equipment to earth ground. • This equipment must be serviced by authorized service personnel only. All repair procedures are detailed to allow sub‐assembly level repairs ONLY. Authorized service personnel should not attempt component level repairs or circuit modifications to the printed circuit board. Improper repairs can create a safety hazard. Determining ONT Enclosure Location General ONT mounting requirements are as follows: • Mount the unit outdoors. • Proper airflow in and around the equipment must be maintained at its final mounted location. Siding and other building material should not be installed around the outside of the enclosure to prevent excessive heat buildup and ultimate product failure. • The unit should be mounted within proximity of the AC electrical power meter where the Multi‐Ground Neutral (MGN) is easily accessible. • The unit should be mounted away from down spouts, permanent water sprinklers, or other water sources. • Consideration should be given to proper clearances for opening of the swinging ONT covers. The height of the mounting can vary, however it is recommended that the enclosure be installed at a vertical distance of approximately four feet from grade. This height lends to ease of installation/repair. Naturally, this mounting is dependent on the height of the customer provided inside wire and/or length or location of the buried fiber drop, which is assumed to enter the ONT from the ground upwards. The enclosure is mounted vertically. If at all possible, the enclosure should be surface mounted on a flat surface. 6418770XGX-5B... -

Commissioning and Testing Commissioning and Testing This section provides detailed information on the following: • Turn‐Up, see below • Depending on the local service provider’s requirements the technician may be required to perform additional tests beyond the ONT on the Customer Premises Equipment (CPE) wiring and/or equipment. If this is the case, a GPON power meter may be used to test the upstream and downstream signal types for voice, data and video. • “Secure the Unit” on page 38 • “Test for POTS Line Faults” on page 38 • “Provision Ethernet Interface at OLT” on page 39 Turn-Up Initial turn‐up of the ONT involves applying power and observing LEDs for status infor‐ mation. To complete the turn‐up of the ONT, complete the following steps: 1.Plug the green UPS connector into the male connector of the UPS. 2. Check to ensure the AC, output, and battery LEDs are green and functioning. The UPS is now ready for normal operation. 3. View the LEDs on the ONT as they cycle through start‐up diagnostics. A properly installed ONT cycles through a sequence of operations during startup and power‐up phases. Table 9 on page 38 shows the normal LED status once the startup and power‐up sequences are complete (approximately 30 seconds) In addition to the front panel LEDs, the ONT has LEDs that are integral to the Ethernet RJ‐ 45 jacks. 6418770XGX-5B... -

Page 49: Provision Ethernet Interface At Olt
Troubleshooting Provision Ethernet Interface at OLT Provision and unlock the Ethernet port to be used at the OLT. For the provisioned Ethernet link, use external equipment (for example, a laptop computer) to verify the Ethernet link is active. NOTE Refer to the Total Access 300 GPON 2.5G 2‐Port Access Module Installation and Maintenance Practice (P/N 61187500E1‐5) for details on provisioning the ONT. Troubleshooting Two principles should be kept in mind when troubleshooting an ONT unit: • Because voice and data signals originate at the OLT equipment, a failure of all services normally indicates the problem is before the ONT. A failure at the OLT equipment normally results in a loss of service to multiple customers. • The OLT has diagnostic testing procedures that can monitor the status of every ONT in the system, which very often can direct you to the root cause of the trouble. NOTE If the home telephone wires are connected to the Two‐screw Terminal Bridge, then the RJ‐11 jack serves as a test access point. In this configuration, inserting a telephone cable into the RJ‐11 jack will disconnect the ONT from home wiring and connect the ONT to the inserted cable instead. This allows the home owner or service provider to diagnose ONT or home wiring related problems. Inserting an RJ‐11 jack (such as a telephone cable or telephone test set) into the connector, will connect the telephone set to the Single Family Unit (SFU) and also disconnect the subscriber service from the SFU. Hence fault may be isolated to the SFU or premises wiring. This section describes how to troubleshoot and correct the following: • “Faults Indicated with LEDs” on page 40 • “ONT Trouble Isolation” on page 40 • “ODN Interface Troubleshooting” on page 42 •... -
Page 50: Faults Indicated With Leds
Total Access 300 GigE SFU ONT Installation and Maintenance Guide Faults Indicated with LEDs Begin troubleshooting at the ONT by checking to see if all LEDs are in their normal state, shown in Table 9 on page 38. There are separate LEDs for each Ethernet RJ‐45 jack that appear on the SFU circuit board. If the LEDs are in their normal state, refer to “LEDs in Normal State” on page 40. If the LEDs are in a fault state, refer to “LEDs in Fault State” on page 40. LEDs in Normal State If the LEDs are in the normal state but you are still having problems, perform the following troubleshooting steps: 1.If the trouble is of a random or intermittent nature, check for loose or broken connections at the common mounting platform. 2. If the trouble is solid, remove the Customer Provided Equipment (CPE) wiring and perform the following tests: • POTS tests described in “Test for POTS Line Faults” on page 38. • Ethernet tests described in “Provision Ethernet Interface at OLT” on page 39. Verify the OLT can run and pass the loop‐back tests for the Ethernet port. If the above tests are successful, the indication of the trouble is directed back toward the ... -

Page 53: Cleaning And Inspection Of Components
Troubleshooting The ODN interface within the ONT at the customer premises consists of the elements depicted in Figure 25. Figure 25. ONT Fiber Connection Cleaning and Inspection of Components Because the physical size of the transmission core of the optical fiber is typically only 9 microns in size, debris such as a single particle of dust or smoke or strand of hair can impair the path enough to cause transmission problems. This section provides information and procedures for the following: • “Cleaning Suggestions” on page 43 • “Cleaning the Connectors” on page 44 • “Cleaning the Bulkhead” on page 44 Cleaning Suggestions Following is a list of suggestions for cleaning connectors, ferrules, and bulkheads: • Always maintain dust caps and dust plugs installed when connectors or adapters are not mated. Store spare dust caps in a zip‐lock bag when not in use. • Avoid allowing unmated connectors to touch surrounding unrelated surfaces and do not touch a connector or bulkhead ferrule for any reason other than while performing the cleaning process. • Use a fiberscope or videoscope to verify proper cleaning of connectors prior to mating connecting components together. • Use an appropriate quality fabric type cleaner and pure alcohol (reagent grade, 99.5% pure) when cleaning the endface of connectors. The alcohol can be applied with either ... -
Page 54: Cleaning The Connectors
Total Access 300 GigE SFU ONT Installation and Maintenance Guide Cleaning the Connectors To clean the connector, complete the following: 1.Wrap the cleaning wipe around the exposed connector endface, apply firm pressure, and twist the wipe around the ferrule back and forth in quarter to half‐turn rotations at least three times. 2. Press the endface of the ferrule directly into a clean, wet spot on the wipe and twist the ferrule while applying pressure to perform a wiping action. 3. Inspect the endface of the ferrule with either the fiberscope or videoscope. If further cleaning is warranted, use the fabric type cleaner to continue cleaning according to the cleaner instructions. Remember an angle polished connector is in use so refer to that specific section of the fabric type cleaner’s instructions. Cleaning the Bulkhead To clean the bulkhead, complete the following: 1.Remove any dust caps or connectors from bulkhead. 2. Insert a new fabric spiral wrapped cleaning tip into the ferrule of the bulkhead. 3. Using your fingers, apply a firm pressure to the cleaner as you twist the cleaner handle two or three times to create a wiping action of the cleaning tip on the ferrule endface. 4. Discard the cleaning tip after using on a bulkhead. Signal Level Verification The following sections detail signal level verification if problems are encountered when ... -
Page 55: Upstream Signal Level Verification
Troubleshooting filtering so that you do not obtain an undesired reading of the absolute optical power from all contributing wavelengths. Instead you are trying to measure the individual wavelength optical power levels. 3. Connect optical fiber drop cable to the test equipment as shown in Figure 26. 1490 nm Drop cable OLTS Figure 26. Downstream Test Configuration 4. Verify the test equipment measurement results are within the optical signal level ranges described in Table 11 above. 5. Do one of the following: • If the results are not within range, perform the necessary testing and verification steps to validate points further up the network, towards the OLT, to locate the cause of the optical signal level differences. • If the measurement results are within range, perform the steps in “Upstream Signal Level Verification” on page 45. Upstream Signal Level Verification A valid optical power level delivered by the ONT must be received by the OLT on the GPON to assure proper ONT ranging and operation. The laser output of the ONT is burst mode at 1310 nm that is controlled in the upstream direction by grants given by the OLT. The individual optical power level that should be present at the optical bulkhead that is located on the ONT is listed in Table 12. Table 12.
