SEESUO is one of the largest and best 1.25gbps sfp duplex wdm cwdm dwdm transceiver module manufacturers and suppliers with rich experience. Welcome to buy our high quality products or wholesale our customized 1.25gbps sfp duplex wdm cwdm dwdm transceiver module in stock with our factory.
The SFP transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA) and SFF-8472. The transceiver consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the DFB laser, and the PIN . The module data link up to 80KM in 9/125um single mode fiber. It offers a simple and convenient way to interface PCBs to single mode fiber optic cables in Dense Wavelength Division Multiplexing (DWDM) applications. It is a high performance, cost effective module for serial optical data communication applications.
The optical output can be disabled by a TTL logic high-level input of Tx Disable, and the system also can disable the module via I2C. Tx Fault is provided to indicate the degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of the receiver or the link status with the partner. The system can also get the LOS (or Link)/Disable/Fault information via I2C register access.

FAQ:
What is compatible with 1.25 g SFP?
1.25G-SFP-20DI SFP Transceiver is fully compliant to SFP Multi Source Agreement INF-8074i. Consequently, it means that module is compatible with 80% of networking equipment, where is not implemented a special algorithm for protection against third party modules.
What is DWDM SFP?
Dense Wavelength Division Multiplexing (DWDM) Small Form-Factor Pluggable (SFP) transceiversprovide the high speeds and physical compactness that today's networks require while delivering the deployment flexibility and inventory control that network administrators demand.
What is the difference between CWDM and DWDM SFP?
Compared to DWDM, CWDM is easier to deploy and manage as it needs fewer optical hardware components. Additionally, CWDM uses wider wavelength spacing, which helps bring down costs. CWDM systems generally use 8, 16, or 32 channels, while DWDM systems can support up to 96 channels.

What does dwdm stand for?DWDM stands for Dense Wavelength Division Multiplexing. It is a technology used in fiber-optic networks to increase bandwidth by combining and transmitting multiple data signals simultaneously over the same optical fiber, each using a different wavelength of light. This enables efficient long-distance communication with high data capacity.
-
What is the difference between cwdm and dwdm?The main difference between CWDM (Coarse Wavelength Division Multiplexing) and DWDM (Dense Wavelength Division Multiplexing) is in channel spacing. CWDM uses wider spacing (typically 20 nm), allowing for up to 18 channels, making it suitable for shorter distances. In contrast, DWDM has narrower spacing (0.8 to 1.6 nm), enabling many more channels (up to 80 or more) for long-distance transmission.
