SFP 2.5G 20km 1310nm SFP Module Duplex LC DDM
Product Description
The SFP SM series single mode transceivers is small form factor pluggable module for bi-directional serial optical data communications. It is with the SFP 20-pin connector to allow hot plug capability. This module is designed for single mode fiber and operates at a nominal wavelength of 1310 nm.
The transmitter section uses a multiple quantum well laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses an integrated InGaAs detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC.
The SFP SM (I) series are designed to be compliant with SFF-8472 SFP Multi-source Agreement (MSA).
Features :
1. Industry standard Small Form Pluggable (SFP) package.
2. Digital diagnostic monitor interface compliant with SFF-8472.
3. Differential inputs and Differential outputs compliant with LVPECL and CML.
4. TTL signal detect indicator.
5. RoHS compliant.
6. Hot-pluggable capability.

Q&A
Q: What kinds of custom choices are offered in YXFiber?
A: As for customized transceivers, YXFiber offers regular custom choices such as compatibility, transmission distance, operating temperature, label pattern, label colors and etc. What's more, YXFiber welcomes any inquiry for customized products and solutions for all need and specifications.
Q: Why should I trust YXFiber compatible transceivers?
A: Besides the price advantage, we have compared to branded transceivers, YXFiber compatible transceivers also maintain the same performance and reliability. To satisfy our customers' needs of high performance, all of our transceivers are tested multiple times in mainstream original brand switches in our test center before shipped out.
Q: Can we use APC connectors on this?
A: Hi, as the default type is UPC, so it's only can be connected with UPC connectors. Thanks
Q: Once I place an order for my transceivers, how long will it take to receive them?
A: Normally you can receive the goods within 7 workdays
Q: Will using compatible optics in my equipment negatively affect my manufacturer's warranty?
A: No. Network equipment manufacturers do not require that you use only name-brand optics. In fact, when a product fault or defect occurs in the network, and the fault or defect is not attributable to the use of third-party optics, they will continue to provide support for the affected product under warranty or covered by their support program.
