25G SFP28 CWDM article focuses on Passive CWDM (Coarse Wavelength Division Multiplexing) 3rd generation which is one of xWDM technologies. Advancing from 10G Ethernet per channel to 25G Ethernet per channel. A short recap - CWDM multiplexes a number of optical carrier signals onto a...

100G PAM (Pulse Amplitude Modulation) are gaining ground in transceiver market and is encouraged by many but is it THE future? Many also say that future perspectives are grand, full with optimism as this technology is embraced by CISCO, HUAWEI, ARISTA to name a few....

It is quite common when we receive questions from our customers as this example “Hey – we have available one dark fiber between our two network nodes and we need to organize 6x10G bi-directional links over that fiber and distance is about 30km. Future plans...

SFP type and BiDi SFP type optical modules are very popular and widely used in optical communication while CSFP (Compact Small Form-Factor Pluggable) optical transceivers are much more rare. In this article we would like to explain main difference between SFP, BiDi SFP and Compact...

SFP-10G-SR nowadays in 2017 is industry leading mainstream optical module in terms of quantity used. Definitely, 40G and 100G optical transceivers are becoming increasingly popular, but because of stable technology (first SFP+ modules arrived in market already by 2006) and it’s reduced pricing SFP-10G-SR is...

Why 10G Copper SFP+ transceiver is good option to have, but can’t be recommended for mass scale data center deployments? Already more than year 10G Copper SFP+ transceivers have become widely available for networking industry. Also we see raising demand for this product and most...

Already for some time tunable optical transceivers for use in DWDM systems, such as XFP and SFP+ are available for optical networking industry. Current evolution of tunable optical transceivers typically support full ITU-T C-band, allowing dynamically tune transmitter wavelength with 50GHz steps. However, even longer...

It is no secret that most IT companies currently uses or has future plans to start using 3rd party optical transceivers - because of simple fact that they are much more budgetary than Original Equipment Manufacturer (OEM) optical transceivers. Doubts of using OEM hardware or 3rd party hardware are...

On March 2013 Cisco announced launch of it’s proprietary 100G optical transceiver module called CPAK. Unless other pluggable optic form-factors like XFP, SFP+, QSFP, CFP, CFP2/4 with are industry standard (Multi-Source Agreement MSA), CPAK is totally Cisco proprietary. What makes CPAK Different? CPAK was first transceiver using...

The CFP module is a hot pluggable form factor designed for optical networking applications. CFP is acronym from 100G (C = 100 in Roman numerals; Centum) Form factor Pluggable. As name suggests, CFP is introduced to serve as optical transceiver for 100G interfaces. There are...
