Nokia 3HE15277AA: Product Description
QSFP28: Form Factor package. This is a standard specification for the appearance and electrical interface of optical modules. QSFP28 stands for "Four-Channel Small Hot-swappable", supporting 4x25G channels and specifically designed for 100G applications. It looks similar to QSFP+ (for 40G), but has a higher electrical interface rate.
100G: Transmission rate. The data transmission speed of this module is 100 gigabits per second (Gbps).
FR: Standard Protocol. Representing "100G-FR", it is a 100G optical interface specification defined in the IEEE 802.3ba standard.
Wavelength used: The central wavelength is 1310nm.
Modulation method: PAM4 (Four-level Pulse Amplitude Modulation) modulation technology is adopted, which is the key to achieving high-speed transmission in a single channel.
Physical channel: Single fiber bidirectional (BiDi). The FR standard only uses a single single-mode optical fiber for transmission. Through wavelength division multiplexing (WDM) technology, it simultaneously transmits and receives optical signals of different wavelengths within a single fiber (typically transmitting about 1295nm and receiving about 1300nm, or similar combinations).
2KM: Maximum transmission distance. It can transmit up to 2 kilometers on single-mode optical fiber (SMF).
SINGLE LAMBDA: Single wavelength. This is directly related to the "FR" protocol. Although the QSFP28 has 4 electrical channels (4x25G),
However, it converts and combines four electrical signals into one optical signal (using PAM4 modulation) through an internal Gearbox chip,
and transmits it on the optical fiber using only one optical long-pass (1310nm window). This is different from the scheme that uses four independent wavelengths (CWDM4).
DOM: Digital Diagnostic Monitoring. This is a very important function. The module is equipped with a built-in microcontroller that can monitor，
and report its working status parameters in real time, such as:
Transmit optical Power (Tx Power), receive optical power (Rx Power), operating Temperature (Temperature), Supply Voltage (Supply Voltage)
Laser Bias Current. This enables network operation and maintenance personnel to remotely diagnose the quality of optical fiber links, predict faults in advance, and greatly facilitates network management.
Optical fiber type: Single-mode optical fiber (SMF). This module must be used in conjunction with single-mode optical fibers to achieve a transmission distance of 2 kilometers.
Summary description: The Nokia 3HE15277AA is a commercial-grade optical transceiver module that complies with QSFP28 packaging and the 100G-FR standard. It adopts PAM4 modulation and single-wavelength BiDi technology.
A single-mode optical fiber is used to achieve a maximum data transmission of 100Gbps over a distance of 2 kilometers, and it also supports complete digital diagnostic monitoring functions.
Application scenario: The core design goal of this optical module is 100G high-speed interconnection from short to medium distances, and it greatly saves precious optical fiber resources. Its main application scenarios include:
Data Center Interconnect-DCI
Server-to-leaf switch (ToR) : In large data centers, high-performance computing (HPC) or AI server clusters need to be connected to the top of the cabinet (ToR) switch via a 100G interface.
Spine-leaf Architecture: Build a 100G high-speed backbone connection between the spine (core) switch and the leaf (access) switch. Since the distance between cabinets in the computer room is usually within a few hundred meters, a transmission distance of 2 kilometers is more than sufficient.
2. Intra-Campus Link between Data Center Buildings
Achieve 100G interconnection among different buildings or data center computer rooms within the same park.
A distance of 2 kilometers is sufficient to cover most park scenarios, and since only one optical fiber is needed, it can significantly reduce the cost and complexity of optical fiber cabling.
3. 5G Mobile Fronthaul/Midhaul
In the 5G network architecture, the BBU (Baseband Processing Unit) needs to be connected at high speed with the distributed AAU (Active Antenna Unit).
The 100G-FR module is highly suitable for 5G fronthaul or midhaul networks due to its high speed and single-fiber cost-saving feature.
4. Core of enterprise network and campus network
The interconnection between core routers and core switches in large enterprises or universities requires 100G bandwidth to aggregate traffic and build a high-speed network core.
