Did you know some good information about transceiver,today I will introducts the transceiver knowledge,they may be the fact that Optical module,sfp module and BiDi SFP.
Optical module:
The optical module comprises with the optoelectronic devices, the functional circuit and also optical interface, the optoelectronic device provides a transmitter and receiver into two parts. Emitting portion is: enter a definite bit rate signal from the internal driver chip processing to get a semiconductor laser (LD) or simply a light emitting diode (LED) to emit a corresponding rate on the modulated optical signal, the automatic control circuit with the internal optical power, so your optical signal output power is kept stable. Receiving portion which may be: the input module of the certain bit rate on the optical signal into a signal by light detecting diode conversion. After preamplifier output electrical signal of the corresponding bit rate.
Said optical module is actually a photoelectric conversion, the transmission side converts the electrical signal into an optical signal, and after that optical signal is become an energy signal with the optical fiber transmission, the receiving end. The sunlight modules include optical receiver module, optical transmitter module, Optical transceiver module, optical transponder module.
FiberStore produce and stock for the wide choice of optical transceivers. The whole fiber transceivers are 100% appropriate big companies like Cisco, HP, Juniper, Nortel, Force10, D-link, 3Com, and backed from a lifetime warranty. Buy confidently. You can easily customize optical transceivers to fit your specific requirements. Write to us individuals chose the item that you just need.
sfp module:
Small form-factor pluggable (SFP) is known as a compact optical transceiver module utilized in optical communications for telecommunication and knowledge communications applications. SFP transceiver given that the upgrade form of GBIC module, possibly be called Mini GBIC. SFP Module are supposed to support SONET/SDH, Gigabit Ethernet, Fibre Channel, Optical Supervisory Channel OSC SFP and various other communications standards.
Fiberstore supply various types of sfp module 100% working with Cisco, HP, Juniper, Netgear, DELL, CWDM SFP , DWDM SFP , BIDI SFP and 10G SFP.
BiDi SFP:
BiDi (Bidirectional) sfp module WDM achieve an optical fiber bidirectional transmission of optical signals. Usually optical module has two ports, TX transmit port RX for getting port; only 1 port within the optical module, to remain filtered from your filter inside optical module, while completing the 1310nm optical signal transmitting and 1550nm optical signal received or vice versa. Therefore, the module can be used in pairs, his greatest advantage is always to save fiber resources.
Fiberstore supply some BIDI SFP products,the bidi sfp cable type is Single-Mode Fiber (SMF),and also the transfer distance we provides BiDi sfp 20km,BiDi sfp 40km,BiDi sfp 80km three kinds from fiberstore.
FiberStore is usually an professional manufacturer and supplier of transceivers. Every one of our transceivers are tested in-house ahead of shipping to that they can get to perfect physical and condition. We guarantee transceivers to get results within your body and each of our transceivers come with a lifetime advance replacement warranty.If you want some transceivers, Gives you a great you're consumers fiberstore.
