Copper SFP Module Among SFP Transceivers

As the improvement of network, it will be important to maintain both configuration flexibility and port utilization for equipment deployed in the intersection of legacy copper and newly installed optical networks. Copper SFP (small form factor pluggable) module ensures the SFP form factor have emerged because the best way to optimize port-level flexibility. The maturation of Copper SFP module is playing a vital role in enabling system designers to meet these objectives while simplifying their inventory and reducing operating costs.

Copper SFP Module

Copper SFP module utilizes a copper line for linking. The copper transceiver includes transmit and receive two decision points, Radiating portion includes laser circuit and optical maser, Receiving part consists of PIN, TIA and Limtiting Amp, completion of digital signal transparent O/E, the E/O conversion functions. Typical copper SFP items like Cisco GLC T and SFP GE T, these SFP modules are used in Gigabit networks and they’re fully suitable for 1000Base-T. SFP GE T may be the copper SFP that are with extended working temperature and DOM support. And I will talk about the common widely used 1000BASE-T copper SFP module below.

1000BASE-T 1000Base T SFP module means the little form fiber optic transceiver that complies with 1000Base-T standards. 1000Base T SFP is copper SFP transceivers and it uses category 5 cables for linking and with a very limited working span. 1000Base T SFP is made for Gigabit Ethernet and it works under IEEE 802.3 standards.

Specifications of 1000BASE-T copper SFP module: 1.25 gigabyte Ethernet over cat 5-cable; Extended case temperature range; Switch, router to switch, router link; High-speed I/O for file severs; compliant using the Gigabit Ethernet and 1000BASE-T standards as specified by IEEE 802, 3-2002 and IEEE 802.3ab; support 1,000 Mbps full duplex data-links with 5-level pulse amplitude modula-tion (PAM) signals; provide standard serial ID information compliant with SFP MSA, which may be accessed with address of A0h via the 2-wire serial CMOS EEPROM protocol; The physical IC can also be accessed via 2-wire serial bus at address Ach; Qualified to satisfy the intent of Bellcore reliability practices; Compliant with SFP MSA specification and SFF-8472 ; Links of narrow, intermediate or long reach with single or Multi-mode fiber; ROHS, CE and FCC certified; DMI feature on request.

FiberStore Technology, a professional fiber optic products supplier, offers the copper SFP module that are made based on IEEE standards, these copper SFP transceivers are suitable to use using the equipment and devices that are with copper SFP slots or ports. The copper SFP module offers a flexible and simple method to be installed into SFP MSA compliant ports at any time with no interruption of the host equipments operation. It enables for seamless integration of fiber with copper LAN connections wherever SFP interface slots can be found. Such system is economical, it saves time, offers flexibility and eliminates the necessity for replacing entire devices once the customers have to change or upgrade fiber connections and you will benefit so much from it.
