Understanding the 40G QSFP+ LR4 10km Transceiver for SMF Technology

Newsunn’s 40G QSFP+ LR4 10km transceiver for SMF represents a significant advancement in high-speed networking. Understanding its underlying technology reveals its capabilities for modern data infrastructure.

The QSFP+ Form Factor for 40G Transceivers

The Quad Small Form-Factor Pluggable Plus (QSFP+) form factor is a cornerstone of 40 Gigabit Ethernet. It offers a compact and efficient design for high-density network equipment.

Benefits of Compact Design

The compact design of QSFP+ modules provides substantial advantages. It allows for greater port density on network devices. A single QSFP+ port can aggregate four 10 Gbit/s channels. This aggregation forms a single 40 Gigabit Ethernet link. For example, a 24-port QSFP+ 1U switch can support 96 individual 10GbE connections. This significantly enhances the number of connections available in a limited space.

Hot-Pluggable Functionality

QSFP+ transceivers feature hot-pluggable functionality. Network administrators can insert or remove these modules without powering down the host equipment. This capability simplifies maintenance and upgrades. It also minimizes network downtime, ensuring continuous operation.

LR4 Standard Explained for 10km Transceivers

The "LR4" designation in the transceiver’s name is crucial. It signifies "Long Reach 4-lane" capability. This standard defines how the module operates over extended distances.

Long Reach Capabilities

The LR4 standard specifically targets long-distance transmission. It enables data transfer up to 10 kilometers over single-mode fiber (SMF). This reach makes it ideal for connecting distant network segments. It supports critical applications like data center interconnects and enterprise networking.

4-Lane CWDM Operation

The 40G QSFP+ LR4 transceiver converts four 10G electrical signals into four distinct optical wavelengths. It then multiplexes these wavelengths onto a single fiber strand. At the receiving end, the module performs the reverse process. It demultiplexes the optical signals back into four separate electrical data outputs. This 4-lane Coarse Wavelength Division Multiplexing (CWDM) operation efficiently utilizes the fiber optic cable.

Single-Mode Fiber (SMF) Essentials for 40G Transmission

Single-Mode Fiber (SMF) is indispensable for the Newsunn 40G QSFP+ LR4 10km transceiver. It provides the necessary medium for long-distance, high-speed data transmission.

Core Diameter and Light Propagation

SMF has a very small core diameter, typically around 9 micrometers. This small core allows only a single mode of light to propagate through the fiber. This characteristic prevents modal dispersion, a common issue in multi-mode fiber. Modal dispersion causes light pulses to spread out, limiting transmission distance.

Advantages for Long-Distance 40G Transceiver for SMF

SMF exhibits significantly less signal attenuation over distance compared to Multi-Mode Fiber (MMF). This allows it to transmit data much further. OS2 SMF cables can extend up to 200 kilometers, supporting high data loads. The absence of modal dispersion in SMF enables much longer transmission distances for 40G and 100G links. This makes SMF the preferred choice for the 10km reach of the Newsunn 40G QSFP+ LR4 module.

Newsunn’s 40G QSFP+ LR4 10km Transceiver for SMF: Key Specifications

Newsunn’s 40G QSFP+ LR4 10km transceiver for SMF offers robust performance. Its design meets the rigorous demands of high-speed data networks. This section details the critical specifications that define its capabilities.

Optical Parameters of the 40G Transceiver for SMF

The optical parameters are fundamental to the transceiver’s ability to transmit data over long distances. These specifications ensure reliable signal integrity.

Wavelengths and CWDM Channels (1271, 1291, 1311, 1331 nm)

The Newsunn 40G QSFP+ LR4 module uses four distinct CWDM channels. These channels operate at precise central wavelengths: 1271 nm, 1291 nm, 1311 nm, and 1331 nm. This wavelength division multiplexing allows the module to transmit four 10Gb/s data streams simultaneously over a single fiber. The ITU-T G.694.2 standard defines this specific CWDM wavelength grid.

Transmit Power (Tx)

Transmit power, or Tx power, measures the strength of the optical signal leaving the transceiver. An appropriate Tx power ensures the signal reaches the receiver with sufficient strength. Different manufacturers specify varying ranges for their 40G QSFP+ LR4 transceivers. For example, a common range for Tx output is -7 to 2.3 dBm.

Feature	Value
Brand	WHGEARLINK
Description	QSFP 40G 1310nm 10km LC
Data Rate	40G
Package	QSFP+
Wavelength (nm)	1310nm
Reach	10km

TX output (dBm)	-7 to 2.3
RX Sensitivity (dBm)	-11.5
Power Consumption (W)	<2.5W

Newsunn‘s module delivers consistent transmit power within industry-accepted limits. This ensures optimal signal launch into the single-mode fiber.

Receive Sensitivity (Rx)

Receive sensitivity, or Rx sensitivity, indicates the minimum optical power the receiver needs to correctly interpret the data. A lower (more negative) Rx sensitivity value means the receiver can detect weaker signals. This capability is crucial for long-distance transmission. The Newsunn transceiver features excellent receive sensitivity. It effectively captures attenuated signals after traveling up to 10 kilometers.

Optical Budget for 10km Reach

The optical budget represents the maximum allowable signal loss between the transmitter and receiver. It accounts for fiber attenuation, connector losses, and splice losses. For a 10km reach, the Newsunn 40G QSFP+ LR4 transceiver for SMF provides a robust optical budget. This budget guarantees reliable data transmission over the specified distance. It also accommodates typical infrastructure losses.

Electrical and Mechanical Specifications of the 40G Transceiver for SMF

Beyond optical performance, the electrical and mechanical characteristics define the transceiver’s operational efficiency and physical compatibility.

Power Consumption (Max 3.5W)

Power consumption is a critical factor in data center operations. Lower power consumption reduces operational costs and heat generation. Newsunn’s 40G QSFP+ LR4 module has a maximum power consumption of 3.5W. This figure aligns with industry standards for high-performance 40G transceivers.

Vendor	Product Name	Max Power Consumption
AOA Tech	QSFP-40G-LR4	2.5W
Approved Networks	40GBASE-LR4 QSFP+ SMF 1271-1331nm 10km DDM Transceiver	3.5 W
ETU-Link Technology	40G QSFP+ LR4 10KM LC Optical Transceiver	Commercial: < 3.5W, Industrial: < 4.5W

This efficient power usage contributes to a greener and more cost-effective network infrastructure.

Operating Temperature Range (0 to 70°C)

The operating temperature range specifies the environmental conditions under which the transceiver performs reliably. Newsunn’s module operates within a commercial temperature range of 0 to 70°C. This range ensures stable performance in typical data center and enterprise environments.
