What You'll Learn
Ciena switches are used for service delivery
Ciena switches are also used in telecom vendor setups, where they can be shared by multiple customers without the risk of cross-connection or data loss across ports. This feature is important for maintaining data security and privacy for different customers using the same switch.
In networking, Ciena service delivery switches are used to convert media formats, such as from SMF to RJ45. They can also be used for multicast video streaming, where a multicast video stream is input into the Ciena switch and then output to a fiber provider. Ciena switches offer flexibility in terms of configuration, where a port can be a UNI or NNI depending on the user's requirements.
Additionally, Ciena switches provide optical module information, which can be accessed through specific commands. This information includes the port type, link status, working rate, real-time working temperature, voltage, bias current, transmit and receive optical power, and alarm information.
Overall, Ciena switches are versatile tools for service delivery, offering adaptability, future-proofing, and robust data security for a range of applications.

Ciena switches have multiple ports
Ciena is a global leader in high-speed connectivity, offering networking systems, automation software, and services that revolutionize data transmission and network management. Their products include the 3916 Service Delivery Switch, which is an advanced Carrier Ethernet demarcation device with robust Quality of Service (QoS) capabilities for Ethernet business service applications.
The Ciena 3916 switch supports 4 GbE NNI/UNI ports, including two 100/1000 Base-X SFP ports and two dual-mode ports: an RJ-45 10/100/1000 Base-T and 100/1000 Base-X SFPs. This switch also incorporates on-board RFC 2544 Performance Benchmark testing capabilities, enabling end-to-end SLA verification without the need for a truck roll.
In addition to the 3916, Ciena offers a range of other switches, such as the 3801 XGS-PON desktop Optical Network Unit (ONU) designed for small and medium-sized businesses, and the 3924 Platform for 10 Gb/s service delivery. The company also provides the 3926 Platform, a compact and flexible CPE platform, and the 3928 Platform, a cost-effective solution for 10 Gb/s service delivery.
Ciena switches, such as the 3930 model, have multiple ports. These ports can be managed and viewed through specific commands. For instance, the command "port show" displays information such as port type, link status, link duration, and working rate. Additionally, the command "port xcvr show" provides identification details, including the vendor name, model, optical module type, and connector type.
The Ciena switches are not typical enterprise switches but are comparable to the Cisco 3400ME or 3750ME switches. Some users have expressed dissatisfaction with the configuration and organization of these switches, while others have found them to be a good choice for their specific use cases.

They are used by companies such as AT&T
Ciena is a global leader in high-speed connectivity, offering networking systems, automation software, and services that revolutionize data transmission and network management. Their products include the 3916 Service Delivery Switch, which is an advanced Carrier Ethernet demarcation device providing Quality of Service (QoS) capabilities for Ethernet business service applications.
Ciena switches are used by companies such as AT&T to deliver high-speed connectivity and advanced Ethernet capabilities. AT&T utilizes the Ciena 3930 switch, which supports optical modules for enhanced functionality. These switches are deployed in a specific configuration, with Ciena connected to an AT&T Router, followed by a corporate switch or firewall. This setup ensures customer WiFi is separate from corporate assets.
The Ciena switches used by AT&T offer multiple ports, including GbE NNI/UNI ports, 100/1000 Base-X SFP ports, and dual-mode ports. These ports provide flexibility in connecting various devices and networks. The segregation of circuits on the Ciena switches is a key concern for AT&T to prevent data loss or cross-talk between different customers.
Ciena switches are also known for their ease of configuration, reliability, and cost-effectiveness. They are widely used in metro Ethernet services and provide robust support for network applications. However, some users have expressed dissatisfaction with the complexity of their configurations, lack of intuitiveness, and the need for additional purchases to manage them effectively.
Overall, Ciena switches play a crucial role in enabling companies like AT&T to provide high-speed connectivity, advanced Ethernet services, and secure network segregation for their customers.

Ciena switches can be used with optical modules
To view the information of the switch port where the optical module is inserted, input the command "port show". This will display the port type (rate), link status of the optical module inserted in the port, link duration, and working rate, among other information. Another command, "port xcvr show", will show the identification information of the switch port, including the vendor name, model, optical module type, and connector type of the inserted optical module.
Additionally, the command "port xcvr" can be used to enter the "(port/xcvr)" mode, followed by the command "show port Port Name diagnostics" to view the DOM information of the optical module. This provides real-time data such as working temperature, voltage, bias current, transmit and receive optical power, and alarm information.
It is important to note that Ciena switches can have authentication operations for accessing optical modules, and unsupported modules may trigger non-authentication alarms. Moduletek Limited provides compatible optical modules for Ciena switches, ensuring proper functionality and compatibility.
