The Huawei CWDM SFPGE LH40 1551 Transceiver is an eSFP ( Enhanced Small Form factor Pluggable) module that operates with a Gigabit Ethernet (GE) capacity and employs CWDM (Coarse Wavelength Division Multiplexing) technology for enhanced data transmission over single mode fiber. This module is designed for high performance, long distance communication and is specified with a wavelength of 1551nm and a reach of 40km, utilizing an LC connector for compatibility with industry standard fiber optic cabling.

In terms of basic information, the transceiver is compliant with the SFP MSA (Multi Source Agreement), which ensures interoperability with various network equipment from different vendors. It is capable of data rates up to 1Gbps and is compatible with IEEE 802.3z standard for Gigabit Ethernet over fiber. The module draws power from an external source via the IEEE 802.3af standard, commonly known as PoE (Power over Ethernet), which simplifies deployment in network environments.

Transmitter and receiver characteristics of the CWDM SFPGE LH40 1551 are tailored for robust and reliable data transmission. The transmitter is designed to modulate the digital signal onto the optical fiber with high fidelity, ensuring minimal signal degradation over the specified distance and wavelength. It also features an automatic power saving mechanism that reduces module power consumption when not transmitting data.

The receiver is capable of detecting and decoding the optical signal transmitted over the fiber, converting it back into an electrical signal that can be further processed by the network device. It has a high sensitivity to ensure reliable detection even over long distances and in the presence of optical noise.

Additionally, the module is designed with a compact form factor, measuring 120.75 x 84.75 x 25.9 mm, making it suitable for a wide range of network equipment where space is a constraint. It is also constructed with robust materials to withstand harsh operating conditions, including temperatures ranging from  40°C to 75°C, ensuring reliable performance in diverse environments.

In summary, the Huawei CWDM SFPGE LH40 1551 transceiver provides a high quality, cost effective solution for Gigabit Ethernet connectivity over long distances using single mode fiber. Its adherence to industry standards and excellent transmitter and receiver characteristics make it an ideal choice for service providers, enterprises, and data center deployments where reliability and performance are paramount.
