How Much Do You Know About SONET/SDH SFP Module?

Over the past decades, Ethernet has been the ubiquitous standard of choice for Local Area Networks (LAN). Traditional SONET/SDH standard seems to be gradually migrating to Ethernet. Could it be said that the SONET/SDH is outdated? Absolutely not. With the expansion of packet-based network traffic in the service provider’s network, SONET/SDH is the dominant technology deployed in most metro and long distance networks. The next generation of SONET/SDH equipment continues to be well accepted by Int...

Everything You Need to Know Before Buying CWDM and DWDM SFP+ Transceivers

It is known to us that WDM (Wavelength-division Multiplexing) can increase network bandwidth by allowing data streams at different frequencies to be sent over a single optical fiber. With the advent of this technology, different wavelengths can be assigned to optical transceiver like CWDM SFP+ & DWDM SFP+ transceiver, thus expanding and optimizing the network capacity. This post aims to be a buyer’s guide of 10G CWDM SFP+ and DWDM SFP+ module selection. CWDM SFP+ and DWDM SFP+ Transceiver...

Difference between LED and Laser Light Source

As the wide application of fiber optic system, optical light source plays a more and more important part in it. We known a basic optical fiber system consists of a transmitter, an optical fiber and a receiver. The fiber optic light source, as an important component of the transmitter is modulated by a suitable drive circuit in accordance with the signals to be transmitted. Optical light source is also needed for performing fiber optic network testing to measure the fiber optic loss in the cable ...

A Quick Overview of Cisco GLC-LH-SM SFP Module

GLC-LH-SM is the Cisco 1000Base LX/LH SFP transceiver module, which is one of the most commonly used SFP module. It is hot-swappable and designed to plug directly into SFP/GBIC interface port or slot in your router and switch for Ethernet & Fibre Channel network applications. But in Match, 2013, Cisco announced the end-of-sale for GLC-LH-SM and substituted it with GLC-LH-SMD. But nowadays, there are still third party suppliers providing GLC-LH-SM SFP module, and there are still research resu...

How Many Types of SFP Transceivers Do You Know

Gigabit Ethernet (GE) came into use in 1999 and has been gradually supplanting Fast Ethernet (FE) in wired local networks, due to the fact of being considerably faster. The transmission hardware used for connecting GE supported devices retains the compact Small Form-factor Pluggable (SFP) package. SFP is often called mini-GBIC (Gigabit Interface Converter). Because it is smaller size and has replaced GBIC modules in most 1Gb applications. The initial Gigabit Ethernet hardware standard was produc...
