Ethernet Services over SDH SFP in a Single Device
OC-3/STM-1 is a network line with transmission speeds of up to 155.52 Mbit/s (payload: 148.608 Mbit/s; overhead: 6.912 Mbit/s, including path overhead) using fiber optics. Depending on the system OC-3 is also known as STS-3 (electrical level) and SDH SFP. These modules are also used for Fast Ethernet application.

CWDM and DWDM Transceiver Solution
CWDM DWDM transceiver modules are used as a part of CWDM or DWDM networks to provide high capacity bandwidth across an optical network. Fiberland CWDM transceivers can operate on 9/125 single-mode fiber to 40km or 80km by using special CWDM channels (1270nm to 1610nm, in steps of 20nm). While DWDM transceiver can support a link length of up to 40km or 80km on single-mode fiber by using special DWDM channels.

SONET and SDH and Optical Module
SONET Synchronous Optical Network is an ANSI standard used in the United States. SDH Synchronous Digital Hierarchy is an ITU standard used in Europe.Both SONET and SDH are very similar, and both transmit data over fiber optic cables. Both standards are point-to-point synchronous networks that use TDM multiplexing across a ring or mesh physical topology. The ATM standard and the FDDI use SONET as the Physical layer.

What is 100G CFP?

With the continuous development of 5G communication technology, 100G modules are gradually becoming popular. We know that there are many kinds of packages for 100G optical modules. From 2000 to now, the optical module package types have been rapidly developed. Its main package types are: GBIC, SFP, XENPAK, SNAP12, X2, XFP, SFP+, QSFP/QSFP+, CFP, CXP. In the fast-developing network era, some 100G optical modules avoid the risk of being eliminated, and upgraded and revised with the wave of the Internet, such as 100G CFP optical modules.

What is CWDM SFP? Which areas does it mainly apply to?

1. What is the CWDM SFP? The CWDM optical module is an optical module using CWDM technology to implement the connection between the existing network device and the CWDM multiplexer/demultiplexer. When used with a CWDM multiplexer/demultiplexer, CWDM optical modules can increase network capacity by transmitting multiple data channels with separate optical wavelengths (1270 nm to 1610 nm) on the same single fiber.

What is AOC and DAC?

AOC is the abbreviation of Active Optical Cables, which is called Active Optical Cables in Chinese. AOC active optical is to encapsulate two optical modules and cable together. Because the medium of transmission in the middle is optical cable, AOC optical module, which contains laser devices, has a higher price for DAC. However, its optical aperture is not exposed, it has high reliability, and its working distance can be customized for a long distance of less than 100 meters.

What is DWDM SFP? What areas does it mainly apply to?

Dense Wavelength Division Multiplexing (DWDM) technology is capable of transmitting data in an optical fiber using bit wavelength parallel transmission or string line transmission using the wavelength of the laser.It is widely used in different fields of communication networks, including long-distance backbone networks, metropolitan area networks (MANs), residential access networks, and local area networks (LANs).The DWDM optical module is the optical module that uses this technology, so the DWDM optical module has high bandwidth and long-distance transmission characteristics.
