CWDM SFP use the SFP interface to connect the equipment and use dual LC PC fiber connector interface to connect the optical network. Typical cwdm sfp include CWDM SFP 1470, CWDM SFP 1490,CWDM SFP 1510,CWDM SFP 1530,CWDM SFP 1550, CWDM SFP 1570, CWDM SFP 1590,CWDM SFP 1610. These CWDM SFP are fully compatible with IEEE 802.3z for 1000Base-X standards and compatible with Fiber Channel Draft Physical Interface Specification.

GLC BX D and GLC BX U are used in pairs, these BIDI SFP transceiver module use 1310nm and 1490nm wavelength via single fiber link, they are Gigabit rate SFP. The GLC FE 100BX U and GLC FE 100BX D are 100Base BIDI SFP, they use 1310nm and 1550nm working wavelength. Bi-directional (BiDi) Small Form Factor Pluggable (SFP) transceiver module series is specifically designed for the high performance integrated duplex data link over a single optical fiber. These transceiver modules are compliant with the SFP Multisource Agreement (MSA). With the hot pluggability, these modules offer an easy way to be installed into SFP MSA compliant ports at any time without the interruption of the host equipments operating online.

x2 transceiver is the 10G fiber optic transceiver, its development was based on former Xenpak standards, X2 10gb transceiver inner function is almost similar with Xenpak, and X2 also can use one transceiver to fulfill all 10G Ethernet optical port function. X2 transceiver is about half size of Xenpak, this enable it suit for density installations.

1000Base T SFP refers to the small form hot swappable fiber optic transceiver that complies with 1000Base-T standards. 1000base-t transceiver is copper SFP transceivers and they use category 5 cables for linking and with a very limited working span. 1000Base T SFP are the SFP transceivers used for Gigabit Ethernet and they work under IEEE 802.3 standards. Typical 1000Base T SFP include Cisco GLC T and SFP GE T.

DWDM SFP is used in DWDM SONET/SDH, Gigabit Ethernet and Fibre Channel applications. dwdm sfp support operation at 100Ghz channel and fully compliant to SFF-8472 MSA. the transmission part of the transceiver adopt a cold DFB laser; the receiver part use a APD photo diode integrated with a TIA, working temperature of this the DWDM SFP range from -5ºC to 70ºC, low power dissipation at less than 1.3W max.
