OC3/STM1 SFP Transceiver
The SOPTO industry-standard Small Form-Factor Pluggable Interface Converter (SFP) for packet-over-SONET/SDH (POS), optical networking, and ATM applications are hot-swappable optical interfaces that can be plugged into a variety of ports on Cisco/HUAEI/Juniper and other mainstream router interfaces. OC3/STM1 SFP transceiver is a high performance, cost effective module that provides full-duplex 155Mbps connectivity between switches.
SOPTO SFP optics for POS and ATM applications plug into a variety of SFP-based POS, TDM and ATM interfaces. The SFPs are compatible with the SONET/SDH and ATM standards, and support the digital diagnostic functions specified in the SFF-8742 Multi-Source Agreement (MSA) and the extended operating temperature range from 23 to185°F (-5 to 85°C).
Sopto’s SPT-P3103-02(D), SPT-P1303-20D, SPT-P1303-40D and SPT-P1503-80D modules are OC3/STM1 SFP modules with duplex LC optical interface. We can also provide DDM functions for your equipment if you need. And these 100BASE SFP transceiver modules are 100% compatible with your branding devices.

The SFP transceiver is not standardized by any official standards body, but rather is specified by a multi-source agreement (MSA) among competing manufacturers.
As a practical matter, some networking equipment manufacturers engage in vendor lock-in practices whereby they deliberately break compatibility with "generic" SFPs by adding a check in the device's firmware that will enable only the vendor's own modules.
For example, in 2003 during a routine Internet Operating System (IOS) update on their Catalyst line of switches, Cisco added a feature that would cause the switch to reject optical modules that were not deemed ‘Cisco brand.
Sopto is a professional manufacture and supplier of fiber optic transceivers. All our optical transceivers are tested strictly before delivery and fully compatible with major bands’ equipment.
Sopto provides GBIC, SFP, SFP+, X2, XENPAK, XFP and QSFP+ transceivers, supporting different data rate such as 1G, 2G, 4G, 8G, 10G, 40G, etc. These transceivers can be operated with network switches, routers, firewalls, digital return transceivers and other devices of all leading vendors, such as Cisco, HP, Juniper, H3C, 3COM, D-link, etc.
As a third party vendor, Sopto can supply transceiver modules with good quality and low price for our customers.
