Optical transmitters and network technologies

What is a transceiver?

 

The Transceiver (Telecom) is an interchange module that connects external communication lines, most often an optical cable. Unlike a fixed built-in communications interface, the user can choose the interface – depending on the type of fiber, the speed and the desired distance transfer. Large quantity of required types of active elements in stock. – Fast swapping is possible without changing the entire element, such as a switch or router.

 

In general, transmitters consist of two transmitter and receiver devices. By composing these two words, the name of the transceiver was created. Even when it is only a transmitter on one side and a receiver on the other side of the line (for example, For unidirectional digital video transmission), we still talk about transceivers.

 

A typical transceiver consists of an optical (or metallic) interface with input connectors, interfaces to an electrical signal, custom electronics for signal processing, power circuits, memory and output connector. The entire transceiver is placed in a standardized case.

Optical connector

The most common optical connector used in transceivers is the LC connector, usually in duplex mode.

Some transceivers also use SC type connectors (older types of bushings or some BiDi single-fiber versions).

Picture – SC connector

 

Multiple optical fiber connectors are used for interfaces where multiple optical fibers need to be connected. These MPO connectors are used for 40GBit, 100Gbit or more transceivers. Versions with 12, 24 and up to 32 optical fibers are used in one MPO connector.

In old versions of transceivers, MT-RJ or VF-45 connectors can still be historically encountered.

Digital diagnostics and EEPROM

 

All today’s types of transceivers contain EEPROM type memory (typically 2 x 256 bytes at 0xA0 and 0xA2 addresses) that contains a whole range of transceiver, interface type, line length, baud rate, manufacturer information, serial number, and so on. data can be read using the embedded serial bus SMBUS and SW management of the active element system in which the transceiver is inserted.

For details, see ftp://ftp.seagate.com/sff/SFF-8472.PDF

 

Most types of transceivers should be ordered in the DDMI (Digital Diagnostic Monitoring Interface) version. This feature enables SW management to continuously detect the transceiver’s operational data such as:

 

  • Received power monitoring (Power or OMA)
  • Transmitted power monitoring
  • Bleeding current of Laser – Bias current monitoring
  • Supply voltage monitoring
  • Temperature monitoring
  • Alternatively, Laser Temp / Wavelength, TEC current (Peltier cell cooling current)
  • Alternatively, exceeded alarm limits – Alarm and Warning thresholds

Transceiver compatibility

All transceiver types used are defined by industry standard MSA (MultiSource Agreement). Mechanically and electrically, all transceivers are interchangeable and the user can choose transceivers from a wide range of manufacturers.

Unfortunately, many active device manufacturers (such as Cisco, HP, Brocade, etc.) store additional encrypted information in the EEPROM memory, or opt for a slightly different solution to the internal transceiver electronics, unlike the MSA standard. For these manufacturers, the user must use original transceivers that are designed for a given range of active elements. Alternatively, so-called OEM compatible transceivers, such as Cisco compatible, Brocade compatible, and so on can be used as a cheaper alternative.

When requesting the delivery of OEM compatible transceivers, please specify the compatibility requirement. If the request for compatibility is not specified when ordering, we deliver OEM Cisco transceivers compatible with DDMI digital diagnostics as standard.

Another possible compatibility issue may arise when the MSA transceiver standard allows several versions of an electrical connection – interface. E.g. For a CFP2 type transceiver, it is possible to use the 10x10GBit, 4x25Gbit, 8x25Gbit, 4x50Gbit, etc. if the active element manufacturer supports only some connection variants, only these versions of the transceivers have to be used. Other connection types will not work in that active element. Similarly, the 100 / 200Gbit transceivers with ACO (Analog Coherent Optics) interface type will not work properly with the version of the interface that is only for DCO (Digital Coherent Optics) transceivers. This is true in reverse.

 

 

Transceivers SFP, SFP +, cSFP

SFP transceiver standard is available for a long time and is used for speeds from 100 Mbit / s to about 6 Gbit / s. For higher speeds, the SFP + specification is already used, whereby the interface and connector interface parameters are improved. SFP + transceivers are available for speeds of up to 28 Gbit / s. (also referred to as SFP28). The SFP and SFP + transceivers are mechanically compatible and some devices can use both types within one slot (e.g., 1G Ethernet and 10G Ethernet).

The so-called BiDi (BiDirectional) transceivers have only one output connector (LC or SC) per thread. The built-in WDM filter allows you to merge two wavelengths into one thread. These BiDi transceivers work in a pair where, on one side of the line, the transceiver is a 1310 nm transceiver, and on the other hand a transceiver with a 1550 nm wavelength is used.

CSFP (compact) transceivers are “double” BiDi transceivers. An extension is used to connect two clients (mostly in FTTH 2x 1GBE networks) in one SFP case each one thread.

Older versions of the transceivers, such as GBIC (Giga-Bit-Interface-Converter), are nowadays virtually not used, replaced by more modern types such as SFP,

 

QSFP +, QSFP28 transceivers

The QSFP type transceiver was developed from the SFP type. The prefix Q as “Quad” means that, unlike the SFP transceiver, a total of four data lines are output at the electrical interface. If the QSFP + version is used, the transceiver allows 40GBit / s (4x10Gbit) transfer rate. QSFP28 type transceivers are used for 100Gbit / s (4x28Gbit).

CFP Transceivers

The CFP-type transceiver was one of the first types to allow 40 to 100 Gbit / s to be used. The electrical interface includes 10 lines of 10GBit. Due to its size and power requirements (up to 35W) it is already replaced by QSFP28 or CFP2. For DWDM applications for 100GBit speeds, such as 10x10Gbit DWDM or DWDM 1x 100GBit with a coherent detector, it is advantageous to use its large case.

DAC (Direct Attach Cable)

DAC cable transceiver solutions are based on a strong connection between transceivers using a shielded metallic twin cable. Depending on design and possible length of interconnection, two technologies are used:

Passive Copper Cable – Direct connection of the electrical interface of the device slots. It is only applicable for short distances up to approx. 5 m.

Active Copper Cable – metallic transceivers are equipped with additional electronics that amplify data signals to allow cable to be used over a longer distance, typically up to 15m.

DAC cables, as opposed to the standard 10GBASE-T metallic interface, have significantly less signal delay and lower power demand. The 10GBASE-T interface, using the CAT6A and CAT7 cables, works longer for up to 100m.

AOC (Active Optical Cable)

AOC cable transceivers are used to connect nearby devices. Unlike conventional transceivers that have an optical connector, there is a firm connection of the optical cable to the transceiver. The cost of the connection is thus reduced by the missing optical connector. The potential risk of dirt and insertion attenuation of the optical connector is also eliminated.

However, it is necessary to know the required length of interconnection in advance. AOC uses an optical cable and is available for longer distances compared to a metallic DAC connection cable. And the optical cable is thinner and more flexible than the metallic cable.

In addition to Ethernet technologies, AOC solutions for InfiniBand, HDMI, USB and DisplayPort are also available. Appropriate use of AOC cables is in datacenters.

Ethernet interface standards

The Ethernet standard is defined by the IEEE (Institute of Electrical and Electronics Engineers). Physical interface of Ethernet is given by the IEEE 802.3 standard.

IEEE 802.3 standards are available at http://standards.ieee.org/about/get/802/802.3.html

For individual Ethernet speeds according to IEEE standards, the basic parameters of the optical transceiver interfaces are also clearly understood.

For other types of interfaces (such as CWDM, DWDM, etc.) that are out of the IEEE Ethernet standard, you need to look into individual transceiver datasheets for more detailed parameters and check the required line spacing.

Fiber Channel standard

Fiber Channel technology is used for high-speed data transmission on SANs (Storage Area Networks). The interface standard itself is defined by the INCITS T11.2 committee http://www.t11.org

 

If you use a transceiver outside of a defined Fiber Channel standard – for example CWDM or DWDM technology, the appropriate parameters and the required transmission distance must be checked using a detailed datasheet for the given transceiver.

Standard SDH technology

Standards for SDH (Synchronous Digital Hierarchy) technologies can be found at the ITU (International Telecommunication Union) website www.itu.int .

From the ITU-T Recommendation, the G Series for SDH Technology, we present the basic parameters of the user interfaces for individual transmission rates, according to G.957 specification.

The “I” user interface is designed for Intra-Office connections with a typical distance of up to 2km. Interfaces “S” (Short-Haul) and “L” (Long-Haul) are designed for inter-office interconnection. The next number shows the baud rate (1 = STM 1, 16 = STM16, etc.). The last number in the interface type specifies the wavelength or, optionally, the type of fiber.

For the STM64 interface, we also provide a new interface designation according to G.959.1.
