What is an (Fiber) Optical Transceiver?
An Optical transceiver module is the core part of optical communication devices. It uses fiber optical technology to send and receive data through completing the process of optical signal – electrical signal / electrical signal – optical signal conversion. An optical transceiver module consists of two parts: the receiving part and the transmitting part. The receiving part realizes the photo-electric conversion, and the transmitting part realizes the electro-optical conversion.
Usually, one end of the transceiver will be connected to a cable and the opposite end of will have a special connector for fitting it into specific models of enterprise-grade Ethernet switches, routers or network interface cards
How to Classify Optical Transceivers?
In order to meet a variety of needs of transmission, the manufacturers launched a variety of categories of optical modules. Below are some common methods to classify them.
1)Sort by Rate
400GE optical transceiver module,
200GE optical transceiver module,
100GE optical transceiver module,
40GE optical transceiver module,
25GE optical transceiver module,
10GE optical transceiver module and etc.
2)Sort by Package
The higher the transmission rate of the optical transceiver, the more complex the structure. In order to meet the needs of different structures, a variety of packaging types of optical transceiver modules were designed. For example, XFP, SFP, SFP+ for 10G transceivers, QSFP+ for 40G transceivers, CFP4, CFP2 and QSFP28 for 100G transceivers, as well as the latest OSFP and QSFP-DD for 400G transceivers.
- XFP (10GB Small Form-factor Pluggable) optical module: “X” is the abbreviation of Roman numerals 10, all XFP modules are 10G optical module. The XFP optical module supports LC fiber optic connectors and supports hot plugging. Compared to SFP+ and SFP optical modules, XFP optical modules are larger and longer.
- SFP (Small Form-factor Pluggable) optical module: smaller than XFP, SFP optical modules support LC fiber optic connectors, hot plugging.
- SFP+ (Small Form-factor Pluggable Plus) optical module: SFP+ refers to the increased rate of SFP module, sensitive to EMI.
- QSFP+ (Quad Small Form-factor Pluggable Plus) optical module: four-channel small hot plugging optical module. The QSFP + optical module supports MPO fiber connectors, which are larger in size than SFP + optical modules.
- CFP (Centum Form-factor Pluggable) optical module: length × width × height of CFP is defined as 144.75mm × 82mm × 13.6mm, high-speed, hot plugging and supporting for data communications and telecommunications applications.
- QSFP28 optical module: the interface package size of QSFP28 is the same with QSFP+, which is mainly used in Data Center application.
- OSFP (Octal Small Form Factor Pluggable) optical module: the OSFP is a new pluggable form factor with eight high speed electrical lanes that will initially support 400 Gbps (8x50G). It is slightly wider and deeper than the QSFP but it still supports 32 OSFP ports per 1U front panel, enabling 12.8 Tbps per 1U.
- QSFP-DD (Quad Small Form Factor Pluggable Double Density) optical module: QSFP-DD is a new module and cage/connector system similar to current QSFP, but with an additional row of contacts providing for an eight lane electrical interface. It is being developed by the QSFP-DD MSA as a key part of the industry’s effort to enable high-speed solutions.
