QSFP28 vs QSFP+
( Difference Between QSFP28, QSFP+ )



QSFP+ and QSFP28 differs in "28" as the name says. QSFP28 is a hot-pluggable transceiver module designed for 100G data rate. QSFP28 integrates 4 transmit and 4 receiver channels. "28" means each lane carries up to 28G data rate. QSFP28 can do 4x25G breakout connection, 2x50G breakout, or 1x100G depending on the transceiver used. While QSFP+ supports the data rate of 40G, 4 channels for transmitting and 4 channels for receiving, each lane carrying 10G. QSFP+ can break out into 4x10G or 1x40G connection.

Usually QSFP28 modules can't break out into 10G links. But it's another case to insert a QSFP28 module into a QSFP+ port if switches support. At this situation, a QSFP28 can break out into 4x10G like a QSFP+ transceiver module. One thing to note is that you can't put a QSFP+ transceiver into a QSFP28 port to avoid destroying your optics.

 

QSFP+ MTP/MPO vs QSFP+ LC
( Difference Between 40G QSFP+ Transceiver With LC Interface And MTP/MPO Interface )




40G QSFP+ Transceivers With LC Interface
From the figure below, we can easily understand the working principle of 40G QSFP+ transceivers with LC interface. In the transmit side, 4 channels of 10G serial data streams at different wavelengths are passed to laser drivers. The laser drivers control directly modulated lasers (DML) with wavelengths. Then the output of the four DMLs are optically multiplexed to a SMF through an industry-standard LC connector, combining as 40G optical signal. In the receive side, the 40G optical signal is demultiplexed into four individual 10G optical data streams at different wavelength. And each wavelength light is collected by a discrete photo diode and amplified by a TIA, and then outputted as electric data. In this process, a 4-wavelength CWDM multiplexer and demultiplexer is used over a pair of single-mode fibers. For transmission distance of this type of 40G QSFP+ transceiver, take 40G LR4 QSFP+ transceiver as an example, it can support an optical link length up to 10 kilometers over the single mode fiber.


40G QSFP+ Transceivers With MTP/MPO Interface
We can easily understand the working principle of 40G QSFP+ transceiver with MTP/MPO interface from the figure below. In the transmit side, the transmitter converts parallel electrical input signals into parallel optical signals through the use of a laser array. Then the parallel optical signals are transmitted parallelly through the multimode fiber ribbon terminated with MPO/MTP fiber optic connector. In the receive side, the receiver converts parallel optical input signals via a photo detector array into parallel electrical output signals. Generally, 40G QSFP+ transceivers with MTP/MPO interface are utilized for short distance transmission over multimode fiber (MMF), like 40G SR4 QSFP+ transceiver, it can support a link length up to 100 meters on OM3 cable and 150 meters on OM4 cable.

What are transceivers?

A transceiver in simple terms can be defined as a device that comprises of both a transmitter and a receiver of analog or digital signals.
Radios and telephones are some of the devices that use transceivers. Network transceivers are used in specific networks like LAN to transmit signals.
Lots of people tend to confuse transceivers and transponders ere is the difference; a transceiver transmits and receives signals anytime while a transponder
only responds to an incoming signal or command.

Transceivers come in three configurations; the chip, board and module style. The chip style is portable and the smallest optical transceiver available.
The board Style unlike the chip style, is in-built in the network system making it permanent while the module Styles are stand-alone devices as they
are not directly installed in the network system.

Modes of Channel operations

Fiber optic transceivers operate in three modes of channels; the simplex, half-duplex, and full-duplex modes.

1. The Simplex mode: This mode of channel operation is one way. It does not send back error information. Since it is one way,
    its use is phasing out and todayit is mainly used in radios.
2. Half-duplex mode: This can only handle a single signal at a time. That is; it can only transmit or receive a signal at a time. Not both.
3. Full-duplex mode: A full-duplex transceiver can handle the reception and transmission of all signals at once. One thing to note though
    is that the transmitter and receiver need to work on different frequencies in order to avoid collisions between transmitted and reception signals.
    Some of the types of Transceivers we offer

GBIC: GBIC (Gigabit Interface Converter) is the media conversion device that connects Gigabit network equipment and fiber optic networks. By use of a GBIC transceiver,
Gigabit network equipment can connect to single mode ports, multimode fiber ports and even copper wires. GBIC is also hot pluggable which enables connection modifications.

SFP: SFP in full is Small Form- factor Pluggable. They are also referred to as mini GBIC due to their similarity in function to the GBIC transceivers though smaller in size.
SFP transceivers are mainly used to link equipment in telecom and data communications like switches and routers. They support applications like Fiber-to-the-desktop (FTTD),
SONET/SDH Network, Gigabit Ethernet, and High-speed computer links among others.

SFP Plus (SFP+): These are an upgraded version of the SFP. The only difference is that they can support up to 10Gbps data rates and are smaller than the 10Gbps X2 and
Xenpak transceivers.

XFP: These are protocol independent optical media conversion equipment used in the SONET/SDH Network, 10G Ethernet and Fiber channel applications. XFP transceivers
are currently the cheapest and the smallest transceivers.

XENPAK: These transceivers support all optical transceiver ports defined in the IEEE 802.3ae. Covering up to 10Km via a G652 multimode fiber he Xenpak transceivers
come in three types which include; Xenpak 10GB SR, Xenpak 10GB LR and the 40km Xenpak 10 GP ER.

X2: These function exactly like the Xenpak because they were built on the Xenpak standards. These optical transceivers?10G Ethernet standards were defined by IEEE in 2002.
