Featured Fiber Optic Transceivers

What is Fiber Optic Transceivers?

● Fiber Optic Transceiver, also called Optical Transceiver or Optical Module, is a tiny packaged device employing fiber optic technology to obtain, an input of data through data cables and transmission through data cables.

● Transceiver combines two words, transmitter and receiver. In other words, the optical transceiver comprises an optical transmitter and an optical receiver.

● Gathered in a unit, they are distinct yet carry out coupled tasks utilizing a shared electrical system or a unified device casing.

It is the central transponder that connects communication equipment through optical fiber cabling. It generally includes Transmit Optical Sub-assembly (TOSA, comprising of LD chip) containing laser, Receive Optical Sub-assembly (ROSA, comprising of photo detector PD chip), a driving circuit, and optical and electrical connection. Its schematic is depicted in Figure 1.

By classification of Fiber-Optical Transceivers?

● Fiber Optical Transceivers have a classification according to packaging types (Form factor), the ratio of incoming data, optical interface working mode, operating temperature limit, whether it supports WDM application or NOT, etc. The breakdown is illustrated in the table below.

Classification method	Results
By form factor	SFP, SFP+, SFP28, QSFP28, CFP2, QSFP-DD, OSFP, etc.
By transmission rate	10Gb/s, 25Gb/s, 40Gb/s, 50Gb/s, 100Gb/s, 200Gb/s, 400Gb/s, 800Gb/s, etc.
By working module of ptical interface	Duplex, BiDi
By operating temperature range	Commercial grade (0~70°C), industrial grade (-40~85°C), etc
Whether wavelength division WDM is supported	Gray light module(WDM not supported),color optical module (WDM supported)

● From GBIC packaging to QSFP+ QSFP-DD packaging, the speed of optical devices has increased from 10Mbis to 800Gbps. At the same time, new improvements of the current technique have allowed them to match the requirements of higher rates with smaller changes in the shape.

● Applying the technology of Wavelength Division Multiplexing, we have developed a new colored optical module that has significantly improved data communication speed over the regular fiber cable. With the introduction of the CWDM (Coarse Wavelength Division Multiplexing), LWDM, MWDM, and DWDM modules into the new Optical Network architecture, the folks on the network are now able to experience longer-distance and increased data speeds for the application such as cloud computing, Video on Demand (VoD), devices such as smart TVs, and gaming consoles.

Main types of color optical modules	Channel interval	Scheme	Cost	Major commercial area
CWDM	20nm	uncooled DML+PIN	low	China
LWDM	800GHz	cooled DML+PIN	medium	Japan and South Korea
DWDM	100GHz	cooled EML+APD	high	North America,Japan, and South Korea
MWDM	CWDM wavelength ±3.5nm	cooled DML+PIN	medium	China

Fiber Optic Transceiver Applications

● It is therefore Fiber Optic Transceivers that go their way in the telecommunications and data centers as a result of different characteristics. The area of telecommunications mainly utilizes it for its wireless front, middle, and backbone transmission, FTTX, etc. With data centers comes the utilization of internal data transmission of primary data centers and data centers interconnection. And also serve the wire-headed networking services like Ethernet, Fiber Channel, SONET/SDH/ONT, CPRI, and FTTx and InfiniBand. The platform is available in the form of LAN switches, routers, firewalls, network interface cards, and fiber optic media converters.

Optical Transceiver Key Factors:

Data Rate – The number of inputted bits in each second shown as 1.25G / 10G / 25G / 40G / 100G / 200G / 400G / 800G.

Central wavelength – This defines the waveband for optical signal transmission. So far, a standard fiber transceivers’ full spectrum includes three wavelengths – 850 nm, 1310 nm, and 1550 nm. The former embraces the first, blue-green, and red wavebands respectively.

Transmission distance: the maximum distance over which optical signals can transmit.

It should be clear because the optical transceiver module supports bidirectional transmission where one optical fiber can be used as the input and the output media.
Therefore, the optical signals can be transmitted through the optical transceiver within the range of several kilo meter lengths or more that is one of the advantages of this type of transceiver over the copper based kind.

Connector Type – Connecting to an optical transceiver via the fiber is the basic part. This is the way we gain access to the analog information carried out by the piece of optical fiber. Some of the most widely used connector types comprise LC connectors (cheap SFP and SFP+, M.2), SC connectors (high-speed 10G SFP+ modules, as well as GBIC and XENPAK-based system), ST and FC connectors (used by 1×9 modules), and MPO connectors (as for the QSFP+ module, also 1×9 transceivers).

Fiber mode: Mode of optical fibers defined based on core diameters and features of optical fibers. Optical fibers are classified into single-mode (SMF) and multi-mode fibers (MMF). The multi-mode fibers have large core diameters and can transport light in multiple modes. However, the inter-mode dispersion is greater so they are used to transmit optical signals over short distances. Single-mode fibers (SMF) have a small core size and can transmit light in only one mode with a small dispersion, so they can transmit optical signals for long-reach communication distances.

Optical Transmit power – When two optical transceivers are interconnectsage then one end must send the transmit optical power which is within the range received optical power on the other end, due to transmitter output optical power and receiver input optical power gp (gain and phase), their values must be close in order to minimize crosstalk and link degradation.

Receiving sensitivity – the minimum optical power needed for decoding receive a bit error rate (BER = 10^-12), expressed in dBm.

Extinction ratio – the ratio of the mean optical power with message sent to the mean power with no signal at all, performed in complete modulation. Extinction ratio is the performance in terms of CM value for fiber transceivers.

Fiber Optic Transceiver FAQs

Q: What procedures should be carried out to maintain optical transceivers?

– Dirty optical interfaces of the transmitter have a bad effect on the signal and decrease the signal power. Therefore, maintenance of the transceiver is much necessary. For the field engineer, use the optical-fiber clean tools and follow the steps below.

– Observe the end face of the connector of the transceiver using the end face checker.

– Select the “L” setting for the one-click fiber cleaner and use it to wipe the transmitter assembly.

– To reactivate the motor, push the button and you will feel a vibration, the dirt from the end face will be shaken off.

Q: Am I allowed to connect a single mode fiber with multimode optical module?

– The answer is no because it is known that the single-band transceiver works using a 1310nm or 1550nm laser, while the multimode module usually has an 850nm laser. The conventional transceiver cannot be tuned.

How We Deliver High Quality

The Concept Of High-Quality Products.

The company not only upholds the philosophy of providing customers with high-quality products but is also able to implement and enforce methods in its production.

IQC before assembly

Incoming Quality Control (IQC) and surface-mounted component inspection are significant to fiber optic transceivers before they are assembled. In terms of the fiber optic transceivers manufacturing field, the suppliers must test the optical emitting module (TOSA), optical receiving module (ROSA), an optical transmitting and receiving module (BOSA) to ensure the quality and performance of transceivers. As for the inspection of surface-mounted components, it is mainly used for checking whether the Printed Circuit Board (PCB) is correct and whether there is pollution, so as to ensure the performance of the fiber optic transceivers.

Testing After Assembly

After the assembly of the optical module is completed, a number of parameter tests are needed to test the signals at the transmitting end (TX) and receiving ends (RX). Only when the parameters like average output optical power, extinction ratio, optical modulation amplitude (OMA), bit error rate (BER) tests, etc. are compliant with the MSA standard, the performance and the quality of modules can be justified.

Qualified By International Certifications

When selecting a qualified third-party module manufacturer, their ability to provide optical transceivers that meet common industry certifications, such as ISO 9001, CE (Construction Electricity), FCC (Federal Communications Commission), and RHS (Restriction of Hazardous Substances) standards, is an important consideration.
