I. Product Description:
This is a 40G optical module that complies with IEEE 802.3ba and QSFP+ MSA standards.
Key Parameters:
1. Rate and Protocol:
Data Rate: 40.0 Gbps (4x10.25 Gbps)
Protocol: Compatible with 40GBASE-LR4 and OTU3 standards.
2. Transmission Distance:
Maximum 10 kilometers (approximately 6.2 miles). This is a classic long-distance transmission specification, suitable for scenarios such as campus networks and data center interconnection.
3. Wavelength and Technology:
Wavelength: 1310nm window. It should be noted that LR4 uses wavelength division multiplexing technology, actually using 4 different lanes, each lane having one wavelength.
Specific 4-channel wavelengths: 1271nm, 1291nm, 1311nm, 1331nm (in accordance with IEEE standards). Inside the module,
these four wavelengths are multiplexed (Mux) onto one optical fiber for transmission, and then demultiplexed (DeMux) at the receiving end.
So although it is 4 channels, the optical fiber link only requires one pair (two) LC single-mode optical fibers.
4. Interface and Connector:
Interface: Duplex LC. This is the most obvious difference from many other 40G modules using MPO/MTP interfaces (such as SR4).
The LC interface is very common and is consistent with the interface of 10G SFP+ LR modules, making wiring convenient.
5. Optical Fiber Type:
Single-mode optical fiber. Single-mode optical fibers of specifications such as G.652.D must be used to achieve a transmission distance of 10 kilometers.
6. DOM Function:
Digital Optical Monitoring. This is a very important function, allowing network administrators to monitor the working status of the module in real time, including:
Output/Input optical power, supply voltage, laser bias current, module operating temperature. This greatly facilitates network operation and fault troubleshooting.
7. Power Consumption:
Typical power consumption is usually below 3.5W, which is a relatively low power consumption level in QSFP+ modules.
8. Operating Temperature:
Commercial temperature range: 0°C to 70°C.
II. Usage Scenarios and Applications
This FTL4C1QE1C module is widely used in the following scenarios due to its 10km transmission capability and the convenience of the LC interface:
1. Data Center Interconnection:
Used to connect core switches, aggregation switches or routers located in different buildings or different data center rooms within the same campus, to achieve 40G high-speed interconnection.
2. Enterprise Network and Campus Network Backbone:
As a high-speed backbone link between the headquarters and branches, or between core devices of various buildings within a university campus.
3. Access Section of 40G Network Long-Distance Transmission:
In the telecommunications network, it can be used as the access link for 40G signals before entering the metropolitan transmission network.
4. High-Bandwidth Device Interconnection:
Connects high-performance servers, storage devices or network devices that require 40G ports.
