Product Description:
The Juniper JNP-QSFP-100G-LR4 (part number: 740-061409) is a high-performance, industry-standard 100Gbps optical transceiver module.
Here are the core features:
1. Form factor and speed: It adopts the QSFP28 package format. QSFP28 is a four-channel small form-factor pluggable package specifically designed for，
100G applications. Its size is the same as QSFP+ (used for 40G), but it supports a higher single-channel rate (28Gbps).
2. Transmission rate: The total data rate can reach up to 100 Gigabits per second (Gbps).
3. Transmission technology: It uses the CWDM4 standard technology. It splits the 100G signal into 4 independent 25Gbps channels, each using a different CWDM (coarse wavelength division multiplexing) wavelength.
Wavelengths: The center wavelengths of these four channels are 1271nm, 1291nm, 1311nm, and 1331nm.
Modulation method: It uses PAM4 modulation, which is a widely used technology in high-speed transmission (such as 50G/100G/400G), and can achieve higher data rates on a single channel.
4. Interface and fiber type:
Interface: Duplex LC interface. Fiber type: Uses standard single-mode fiber.
5. Maximum transmission distance: Up to 10 kilometers. The "LR" in "LR4" represents "Long Reach" (long distance). The "4" in the model number represents 4 wavelength channels.
6. Digital diagnostic function (DDM/DOM): Supports digital diagnostic monitoring functions. Network administrators can monitor the parameters of the module in real time through the Junos OS command-line interface, such as:
temperature, supply voltage, laser bias current, transmit and receive optical power, which is crucial for troubleshooting and predicting network health status.
7. Compatibility: Although this is a Juniper brand module, due to its compliance with the MSA (multi-source agreement) industry standard,
it is usually also compatible with other network devices that support the QSFP28 CWDM4/LR4 standard (such as Arista, Cisco, Dell, etc.).
However, for stability reasons, Juniper officially recommends using Juniper certified optical modules on its devices.
8. Applications: Mainly used for 100G Ethernet links in data centers, enterprise core networks, and service provider networks.
Usage scenarios
This optical module is mainly used in scenarios that require high performance and long-distance 100G interconnection. Here are several typical usage scenarios:
1. Data Center Interconnection (DCI):
Establish high-speed and large-capacity interconnection links between the same campus or different data center buildings within 10 kilometers. It is used for server clusters, data backup, virtual machine migration, etc.
2. Core backbone connection of campus networks or large enterprise networks:
Connect core switches or routers in different buildings to build a high-speed backbone network, carrying all data traffic of the entire campus or enterprise.
3. High-performance computing (HPC) and storage networks:
In HPC clusters that require extremely low latency and ultra-high bandwidth, connect computing nodes, storage arrays, and switches. The 10-kilometer distance also provides flexibility for distributed computing nodes.
4. Service provider networks:
Used for access and aggregation layers of metropolitan area networks (MAN),
providing high-speed uplink links for commercial customers or mobile bearer networks. 5. Interconnection between 100G switches or between switches and routers:
This is the most straightforward application. For instance, connect the 100G ports of two Juniper QFX series or MX series devices using single-mode fiber through this module to expand the network capacity.
In addition to Juniper JNP-QSFP-100G-LR4 740-061409 , 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
