Product Description:
1. Model and Part Number
Model: JNP-QSFP-40G-LR4
Juniper Part Number: 740-052009
Compatible Models: It is also commonly equivalent to the industry-standard model QSFPP-40G-LR4.
2. Form Factor
It adopts QSFP+ packaging. This is a four-channel small form-factor pluggable package, larger in size than the earlier SFP+,
specifically designed for 40G and 100G high-speed connections. It integrates four independent transceiver channels within a single module.
3. Rate and Protocol
Rate: Supports 40 Gigabit Ethernet.
Protocol: Complies with the 40GBASE-LR4 specification in the IEEE 802.3ba standard.
4. Interface and Fiber Type
Fiber Type: Must use single-mode fiber.
Interface: One end of the module is a standard MPO/MTP multi-core interface (for connecting fiber patch cords), and the other end is a QSFP+ interface for the device.
Typically, an MPO to LC duplex branch fiber patch cord is used to connect the MPO interface of the module to the LC interface fiber patch panel in the network.
5. Wavelength Division Multiplexing Technology
It uses CWDM wavelength division multiplexing technology.
It combines four optical signals (channels) of different wavelengths within the module and transmits them over a single-mode fiber, thereby achieving 40G bandwidth on a single fiber. The center wavelengths of these four channels are:
Channel 0: 1295.56 nm, Channel 1: 1300.05 nm, Channel 2: 1304.58 nm, Channel 3: 1309.14 nm.
6. Transmission Distance
The maximum transmission distance can reach 10 kilometers.
7. Digital Diagnostic Function
Supports DDM, also commonly known as DOM.
This means you can monitor the module's operational status in real time through Junos CLI commands (such as show interfaces diagnostics optics), including:
Output/input optical power, supply voltage, laser bias current, module operating temperature. This function is crucial for network operation and maintenance, fault diagnosis, and early warning.
8. Operating Temperature
Typically within the commercial temperature range, suitable for data center and server room environments.
9. Compatibility
This is an original Juniper Networks certified module, specifically designed for Juniper's switches, routers, firewalls, and other network devices (such as QFX series, MX series, PTX series, and other devices supporting QSFP+ ports).
Important Note: Although QSFP+ is an industry standard in theory, to ensure 100% compatibility ,
and stability, it is strongly recommended to use Juniper original or certified compatible modules on Juniper devices to avoid potential compatibility issues and the risk of not receiving technical support. Usage scenarios
The JNP-QSFP-40G-LR4 is mainly used in scenarios that require medium to long-distance, high-performance connections. Typical applications include:
1. Internal interconnection in data centers
Head-of-rack to core switch: In the data center architecture, it is used to connect access layer/aggregation layer switches and core switches, providing high-speed backbone links.
Server aggregation: Connecting high-density 40G switches in high-performance computing clusters or storage area networks.
2. Backbone of campus networks or enterprise networks
Interconnection between buildings: Connecting core or aggregation switches distributed in different buildings within the campus, with a transmission distance of 10 kilometers sufficient to cover most campus environments.
3. Telecommunication operator networks
Metro access and aggregation: Serving as the interface for client connections or base station aggregation connections in the metro network, providing high-bandwidth access.
4. High-performance computing networks
Used for interconnection in HPC clusters that require low latency and high bandwidth.
In addition to Juniper JNP-QSFP-40G-LR4 740-052009 , Liyuan Tech supply a wide range of other Juniper Series transceivers. If you have any need or interest, please feel free to send inquiry to global@chn-liyuan.com
