BIDI/WDM SFP Transceiver
WDM SFP, also called Bi-directional (BIDI) Small Form Factor Pluggable (SFP) transceiver module, is specifically designed for the high performance integrated duplex data link over a single optical fiber. Sopto supplies 155M, 1.25G and 2.5G WDM SFP transceiver modules using a long wavelength DFB laser diode and enable data transmission up to 80km on a single-mode (9/125μm) optical fiber. All our WDM SFP transceivers support DDM functions and fully compatible with your branding devices.
Tips: SOPTO supplies (Original Equipment Manufacture) OEM Service and Third-Party Compatible Fiber Optic Transceivers.

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.
