Competition can be cut-throat, especially in the technology field. It sometimes brings out the worst in companies, people, and tactics where the bottom-line is the first, foremost, and only concern. POFLink is not this,we value relationships.And wed love to spend time to create a good reputation of trust and worthiness with a company.

At POFLink, it goes without saying that we know what it takes to stay in business,


POFLink SFP-XFP LLC was established in 2007 as a global leading supplier for fiber optical components with perfect technique & production, abundant technology development capability of photonics products and network items.

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; 1
10GbE OC-192 STM-64 at 10 Gbit/s.

  • CWDM/DWDM Active and Passive systems;
  • transceivers of SFP, SFP +, XFP, QSFP + and other form factors;
  • components and materials for fiber-optic communication networks ;
  • welding and measuring equipment for optical fibers by leading manufacturers.

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. POFLink transceivers are compatible with the equipment of widespread international vendors such as Cisco, HP,Juniper,3com,Extreme,Huawei,Alcatel,Netgear,D-link,Linksys and others, and support the operation of the majority of data transmission protocols.

We offer competitive "Designed and Made in China" pricing, without sacrificing the Quality and Design.For any further interesting or question about our products, including tech/price/delivery/test sample, please feel free to contact us.
