1. Manufacturer and Model: Ciena 160-9501-900
Ciena: A globally renowned telecommunications network system, software and service company, whose optical network products enjoy a high reputation in the industry.
160-9501-900: This is the unique part number (Part Number) set by Ciena for this product, used for identification, ordering and after-sales service.
2. Technical Standards: 40GBASE-LR4
40G: Indicates that the total transmission rate of this module is 40 Gigabits per second (Gbps).
BASE: Refers to "baseband", that is, single-channel transmission, is a standard Ethernet term.
LR4: The abbreviation of "Long Reach 4". It represents a long-distance transmission standard, using 4 independent laser wavelengths，
(channels) to transmit data on the same fiber, with each channel having a speed of 10 Gbps, combined to 40 Gbps.
3. Channel Technology: 4X10G CWDM
4X10G: Clearly indicates the implementation method of LR4: splitting the total bandwidth of 40G into 4 10G channels.
CWDM: coarse wavelength division multiplexing (粗波分复用). This is the key technology to implement 4 channels. It combines 4 different wavelengths of optical signals into one fiber for transmission at the sending end，
and separates them at the receiving end. The 4 CWDM wavelengths used by the LR4 standard are usually，
around 1271nm， 1291nm， 1311nm， 1331nm (the 1310nm in your title is the central area or abbreviation of this group of wavelengths).
4. Packaging Form： QSFP+
Quad Small Form-factor Pluggable Plus： An industry standard optical module packaging specification. It is compact in size，
has high panel port density， supports hot swapping， and is widely used in ports of 40G and 100G network devices (such as switches， routers)， etc.
5. Wavelength and Transmission Distance： 1310nm 10km
1310nm： Indicates the central wavelength region where the module operates (as mentioned above， it is actually a collection of 4 wavelengths).
10km： Indicates that the maximum theoretical transmission distance of this module on single-mode fiber can reach 10 kilometers.
6. Diagnostic Function： DOM
Digital Optical Monitoring： Digital optical monitoring. This is a very important function， allowing network administrators to monitor the working status of the module in real time， such as：
output/input optical power， supply voltage， laser bias current， module operating temperature， which greatly facilitates the operation and fault troubleshooting of the network.
7. Interface Type and Fiber： Duplex LC/UPC SMF
Duplex： Duplex means that two fibers (one for sending and one for receiving) are required to complete two-way communication.
LC： A small square type of fiber connector， is currently the most mainstream and high-density interface.
UPC： Refers to the end face grinding method of the fiber connector as "super physical contact"，
which is more common in data communication (APC is mostly used in CATV and other scenarios that are sensitive to reflection)
SMF: single-mode fiber (single-mode optical fiber). This type of fiber has a small core diameter and is used for long-distance and high-speed optical signal transmission. In contrast, multi-mode fiber has a shorter transmission distance.
Core functions:
This Ciena QSFP+ optical module is a 40G high-speed network connection module for single-mode fiber, with a transmission distance of up，
to 10 kilometers. It decomposes 40G signals into 4 10G wavelength channels using CWDM technology, combines them, and transmits them over a pair of single-mode fibers, achieving high speed and high port density.
Usage scenarios and applications
This module is mainly used in scenarios that require medium to long-distance and high-bandwidth connections, especially in the core backbone of data centers and enterprise networks.
1. Data Center Interconnect (DCI)
Connects different data center buildings or computer rooms located within the same park or city (within a distance of 10 kilometers) to achieve data synchronization, backup, and load balancing.
2. High-Performance Computing (HPC) and Cluster Interconnection
Provides low-latency, high-bandwidth connections between server clusters or supercomputers that require high-speed data exchange.
3. Enterprise Campus Network/Campus Backbone
Connects core switches or aggregation switches distributed in different office buildings to build high-speed campus network backbone links.
4. Telecommunication Operator Network
Used in metro access networks or aggregation layers to connect 40G services to higher-speed backbone networks.
5. Storage Area Network (SAN) Expansion
Connects remote storage devices, such as extending the storage network through protocols like Fiber Channel over Ethernet (FCoE).
