Cisco uBR10-SRP-OC12SML DPT WAN Line Card for the Cisco uBR10012 Router

Feature Overview

Cisco uBR10-SRP-OC12SML DPT WAN Line Card

78-13602-01

Feature Overview

The Cisco uBR10 Spatial Reuse Protocol (SRP) OC12 single-mode fiber, long reach (SML) dynamic

packet transport (DPT) WAN line card provides shared IP over SONET capability for the

Cisco uBR10012 router platform.

The Cisco uBR10-SRP-OC12SML DPT WAN line card:

•Accommodates large scale network topology.

The WAN card is deployed in SONET OC-12 DPT rings. The DPT rings are connected to SONET

Add Drop Multiplexers (ADMS) allowing the creation of small or very large rings. Each DPT ring

supports a maximum of 64 nodes.

•Leverages fiber optics capacity at OC-12c line rates.

The WAN card has two SC duplex ports. Each SC duplex port provides the physical connection to

an adjacent device in a DPT ring.

•Supports single mode fiber transmissions.

•Allows data to obtain fair-shared access to the OC-12c rings.

•Supports Version 1 SRP Protocol

•Implements protection mechanisms, including wrap and unwrap, in the event of fiber or node

failure.

The Cisco uBR10-SRP-OC12SML DPT WAN line card requires two card slots. For that reason, the card

is normally installed in Slot 2 and Slot 4 if you are using two cards. If you are using only one card than

install the card in Slot 2, Slot 3 or Slot 4. See Figure 1.

Attenuation

The Cisco uBR10-SRP-OC12SML DPT WAN line card is designed to be used at any distance between

15 and 40 kilometers (km). For shorter distance operations (less than 15 km), use a 10 dBm optical

attenuator on the link (see Figure 6 on page 7) between the two nodes to prevent clipping and over

saturation of the optical receiver. The attenuator should be made of a non-metallic or plastic material.

The exact attenuation value is based on the real cable length or the number of couplers and splicers on

the link. For example, 5 dBm attenuator could be used in a 7 km link.

Note The maximum distance of 40 km assumes that the 1310 nm SMF optical cable attenuation is no more

than 0.5dB per kilometer; and that there is no optical coupler or splicer in on the link (each could add

0.5dB loss).

Cisco recommends the use of a SC/PC female to SC/PC male optical attenuator.

Tip The SC/PC (Standard Connector/Physical Contact) denotes a connector with a rectangular shape.

The surfaces are parallel with respect to the port (not angled). SC/APC (Standard Connector Angled

Physical Contact) denotes an angled surface.

Caution Make sure that you obtain the correct connector type (SC/PC) when purchasing optical attenuators.

Angled SC/APC type mating surfaces can damage the Cisco uBR10-SRP-OC12SML DPT WAN line

card (RX port) interface.

Connectors and Cables

The Cisco uBR10-SRP-OC12SML DPT WAN line card uses a single-mode fiber-optic interface cable

to connect the Cisco uBR10012 router to another router or switch. See Figure 6 on page 7.

Single-mode cables are yellow.

Note Single-mode fiber-optic cables are not available from Cisco Systems.

For SONET or SDH single-mode fiber-optic connections, use one duplex SC-type connector (Figure 4)

or two simplex SC-type connectors. See Figure 5.

Figure 4 Duplex SC Cable Connector

Figure 5 Simplex SC Cable Connector

You can use either a duplex fiber cable or two simplex fiber cables between the DPT port line and the

device to which the DPT port line is connected. If you are using an attenuator with the cable, see Figure 6

on page 7.

Hazardous Voltages in WAN Ports

Attention

Il est vivement recommandé de confier l'installation, le remplacement et la

maintenance de ces équipements à des personnels qualifiés et expérimentés.

Warnung

Das Installieren, Ersetzen oder Bedienen dieser Ausrüstung sollte nur geschultem,

qualifiziertem Personal gestattet werden.

Avvertenza

Questo apparato può essere installato, sostituito o mantenuto unicamente da un

personale competente.

Advarsel

Bare opplært og kvalifisert personell skal foreta installasjoner, utskiftninger eller

service på dette utstyret.

Aviso

Apenas pessoal treinado e qualificado deve ser autorizado a instalar, substituir ou

fazer a revisão deste equipamento.

¡Advertencia!

Solamente el personal calificado debe instalar, reemplazar o utilizar este equipo.

Varning!

Endast utbildad och kvalificerad personal bör få tillåtelse att installera, byta ut eller

reparera denna utrustning.

Warning

Hazardous network voltages are present in WAN ports regardless of whether power to

the router is OFF or ON. To avoid electric shock, use caution when working near WAN

ports. When detaching cables, detach the end away from the router first.

Waarschuwing

Er is gevaarlijke netwerkspanning aanwezig in WAN poorten ongeacht of de stroom

naar de router INGESCHAKELD of UITGESCHAKELD is. Om elektrische schokken te

vermijden, dient u voorzichtig te werk te gaan wanneer u in de nabijheid van WAN

poorten werkt. Wanneer u kabels losmaakt, dient u eerst het uiteinde dat zich het verst

van de router vandaan bevindt, te verwijderen.

Varoitus

WAN-porteissa on vaarallisia verkkojännitteitä riippumatta siitä, onko reitittimen

virta kytketty vai ei. Välttyäksesi sähköiskulta ole varovainen työskennellessäsi

WAN-porttien lähettyvillä. Kun irrotat kaapeleita, irrota reitittimestä kauempana

sijaitseva pää ensiksi.

Attention

Les ports de réseau longue distance (WAN) gèrent des tensions de réseau

dangereuses, que le routeur soit sous tension ou pas. Pour éviter tout risque

d’électrocution, prenez toutes les précautions nécessaires avant de travailler à

proximité des ports WAN. Pour déconnecter les câbles, commencez par débrancher

l’extrémité la plus éloignée du routeur.

Warnung

In WAN-Ports sind gefährliche Netzspannungen vorhanden, auch wenn der Strom zum

Router abgeschaltet wurde. Zur Vermeidung von Elektroschock Vorsicht bei der Arbeit

in der Nähe von WAN-Ports. Beim Abtrennen von Kabeln zuerst das vom Router

entfernte Ende lösen.
