How to classify fiber optic transceiver

Optical properties by Category:

 By optical fiber to points, can be divided into multi-mode fiber transceiver and single-mode fiber transceiver.

          Single-mode fiber transceiver: transmission distance of 20-120 km

 Multi-mode Fiber Transceiver: distance 2 km to 5 km, due to the use of fiber is different from the transceiver can transmit not the same, multi-mode transceiver in the normal distance between 2 km to 5 km, while the single mode transceiver covering the range from 20-120 km.Be noted that due to the different transmission distance, fiber optic transceiver itself transmit power, receiver sensitivity and the use of wavelength will be different.



        · Classification according to the required optical fiber:

Single fiber optical transceiver: receiving the data sent in an optical fiber transmission

Two-fiber optical transceivers: receiving data transmitted on a fiber-optic transmission by definition, single-fiber devices can save half of the fiber, a fiber that is in the receive and transmit data, where the fiber is very applicable to resource constraints. These products use the wavelength division multiplexing techniques, mostly using the wavelength 1310nm and 1550nm.



         • Press the working level / rate categories:

      100M Ethernet optical transceiver: work in the physical layer

  10/100M adaptive Ethernet optical transceiver: Working in the data link layer

     At the working level / rate to points, can be divided into single-10M, 100M fiber transceiver, 10/100M self-adaptive fiber-optic transceivers and 1000M optical fiber transceivers. One single-10M and 100M transceiver products work in the physical layer, a layer of work in this product is a bit transceiver to transmit data. The way forward with the forward speed, high permeability, low latency advantages, suitable for a fixed link rate, and because such equipment is not in a previous communication from the normal consultation process, so the compatibilityand better stability.

            · Classification according to structure:

  Desktop (standalone) optical transceivers: stand-alone CPE

    Rack (Modular) optical transceivers: Install the sixteenth-slot chassis, a centralized power supply

    According to sub-structure can be divided into desktop (standalone) rack-mounted fiber optic transceivers and fiber-optic transceivers. Desktop optical transceivers for single users, such as to meet the corridor together on a single switch. Rack (Modular) optical transceiver for multi-user aggregation, such as residential district central office must meet all the switches on the joint, the use of the rack to facilitate the achievement of all the modular fiber optic transceiver for the unified management and unified power, rack-and more domestic product for the 16 slots that can be inserted up to a rack 16 modular optical transceivers.


            · Classification by Type of Management:

   Unmanaged Ethernet optical transceiver: Plug and Play, Set by hardware DIP switch mode power port

   Managed Ethernet optical transceiver: support carrier-grade network management by network management to points, can be divided into managed and unmanaged fiber-optic transceiver-type optical transceiver.



          · Press the power Category:

   Optical transceiver built-in power: built-in switching power supply for telecom power

   External Power Fiber Transceiver: external transformer power supply more equipment to use in the civilian

   Press the power to points, can be divided into two kinds of internal power and external power supply. One built-in switching power supply for telecom power supplies, and more use of external power transformer in the civilian equipment. The former has the advantage to support the wide supply voltage, to achieve better regulation, filtering and power protection equipment to reduce exposure due to external mechanical point of failure; the latter has the advantage of compact and inexpensive equipment.
