Fiber Optic Transceivers

An optical transceiver (TRANSmitter + reCEIVER) is a transceiving device used in fiber-optic networks to transmit and receive data between remote devices: switches, routers, multiplexers and other telecommunications equipment. Transceivers are interface converters, as they provide interaction between the network device interface and the fiber-optic transmission medium.


Dual-fiber modules are used for bidirectional data transmission via two single-mode or multi-mode optical fibers. In these modules are used TOSA (Transmitter Optical Sub-Assembly) and ROSA (Receiver Optical Sub-Assembly).


Single-fiber modules are designed for bidirectional data transmission via a single optical fiber. In these modules installs BOSA (Bidirectional Optical Sub-Assembly) optical assembly, which combines transmitter and receiver in one optical port.


Transceivers support all protocols used at different data transmission rates:

  • OC-3/STM-1/SDH/FE at up to 155 Mbit/s;
  • OC-12/STM -4/SDH at up to 622 Mbit/s;
  • GBE/FC at up to 1.25 Gbit/s;
  • OC-48/STM-16/SDH/GBE/FC at up to 2.5 Gbit/s;
  • GBE/FC at up to 4.25 Gbit/s;
  • 10GBE/10FC/OC-192/STM-64 at 10 Gbit/s.


Depending on wavelength and rate of the transmitted signal in module transmitters, lasers of various types can be installed:

  • FP (Fabry-Perot) laser;
  • EML (Electroabsorptive Modulated Laser);
  • VCSEL (Vertical Cavity Surface Emitting Laser);
  • DFB (Distributed Feedback) laser.


To carry out the on-line monitoring, DDM (Digital Diagnostic Monitoring) function is used. The DDM function allows for real-time control of the following parameters: input signal (RX) power, output signal (TX) power, module temperature parameters.


UpNet transceivers are compatible with the equipment of widespread international vendors such as Cisco, HP, Juniper, 3com, Extreme, Dlink, Huawei and others, and support the operation of the majority of data transmission protocols.
