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.
