Product Description
Finisar FTL4C1QE2L-G3 is a high-performance 40G QSFP+ optical module:
1. Model and Manufacturer:
Manufacturer: Finisar
Model: FTL4C1QE2L-G3. This model code contains its key information: 40G, LR4 standard, 10km transmission distance, 1310nm wavelength, LC interface, etc.
2. Physical Packaging:
QSFP+: Full name is "Quad Small Form-factor Pluggable Plus" (four-channel small form-factor plugable). This packaging size supports four independent full-duplex channels and is widely used in 40G network devices.
3. Transmission Rate:
40 Gigabit Ethernet: The total rate can reach up to 40Gbps.
Compliant with standards: Complies with IEEE 802.3ba 40GBASE-LR4 standard.
4. Wavelength and Technology:
Wavelength: Utilizes coarse wavelength division multiplexing technology, simultaneously transmitting four different wavelength optical channels on a single-mode fiber.
These four channels are located near the 1310nm window, with specific center wavelengths of 1271nm, 1291nm, 1311nm, and 1331nm.
Technology: The module internally multiplexes 4 10Gbps optical signals using a wavelength multiplexer to generate a 40Gbps signal, and then demultiplexes it into 4 independent 10G signals at the receiving end.
5. Transmission Distance:
Maximum 10km: Designed for transmission over a distance of up to 10km through OS2 single-mode fiber.
6. Interface Connector:
Duplex LC interface: There is one duplex LC interface on the module panel. Although there is only one physical interface, the internal part uses CWDM technology to carry four logical channels.
7. Digital Diagnostic Function:
DDM: Supports digital diagnostic monitoring function. Through the network management system, the working status of the module can be read in real time, such as:
temperature, power supply voltage, laser bias current, transmission and reception optical power, which is crucial for predictive maintenance and fault troubleshooting.
8. Power Consumption: The typical power consumption is usually lower than 3.5 watts, making it a relatively energy-efficient 40G module.
9. Operating Temperature: Usually within the commercial temperature range, please refer to the product specification sheet for details.
Application Scenarios and Applications
This module is mainly used in scenarios requiring medium to long-distance, high-performance 40G connections, especially in the core layer of data centers and enterprise networks.
1. Data Center Interconnection:
Top-of-rack switch interconnection: Used to connect TOR switches in data centers to build a 40G backbone network.
Hub layer and core layer switch connection: As a link connecting the hub switch to the core switch, or for interconnection between core switches.
2. Enterprise Network and Campus Network Backbone:
Used to connect core network devices in different buildings, with a 10km transmission distance sufficient to cover most campus or enterprise campus areas.
3. 40G Ethernet Links:
Provide high-bandwidth uplink links for server clusters, high-performance computing or storage area networks.
4. Interconnection with 10G Devices:
Through QSFP+ to 4x SFP+ branch optical fiber jumper, a 40G port can be split into 4 independent 10G ports,
used to connect downstream 10G devices, thereby saving switch ports and costs. This is a very common application.
Key Summary and Important Notes
Core Value: Achieve 10km 40G transmission on single-mode fiber.
Fiber Type: Must use OS2 single-mode fiber, incompatible with multi-mode fiber. Compared with other 40G modules:
vs. 40G SR4: The SR4 uses multimode fiber and has a very short transmission distance (usually 100-150 meters), but it is cheaper.
vs. 40G LR4: This is the standard model of the LR4 module, and 10km is its typical distance. There is also the ER4 (40km) module with a longer distance.
Compatibility: Although it is from the Finisar brand, it follows industry standards MSA and usually can be compatible with most mainstream,
brand network devices (such as Cisco, Juniper, Arista, HPE, etc.), but some devices may require command-line unlocking or the use of certified compatible modules.
