HPE H3C JD118A Compatible 1000Base SFP SX Transceiver Module (850nm MMF 550m LC DDM)
The 1000Base SFP SX transceivers are high-performance, cost-effective modules supporting a data rate of 1.25Gbps and 550m transmission distance and support up to 550m link lengths over LC duplex MMF fiber. Each SFP transceiver module is individually tested to be used on a series of Cisco switches, routers, servers, network interface cards (NICs), etc.

How to choose the suitable SFP Module for your networking?
We help more than 1400 clients choose the suitable transceiver quickly. Here are the essential tips.
-
- Check your switch (or other network devices) port-supported speed and ensure it matches the correct SFP.
- Know your existing network cabling types. If you have a multimode fiber cabling structure, then choose the multimode SFP. If you have a single mode fiber cabling, a single mode transceiver is the only choice.
- Know your target link distance and link budget. But remember, choose an SFP that supports longer transmission distances than expected. Otherwise, poor fiber optic cable or a dirty fiber end face may cause a failed link.
- Considering the operating temperature, a commercial-grade transceiver is enough for a typical indoor environment. In harsh outdoor applications, you should use an industrial transceiver.
- Remember to check compatibility with the supplier before ordering. Because the switch can not recognize an incompatible transceiver, it will waste your money and valuable time. So, always choose a proven compatible transceiver.
FAQ
Q: How does the SFP differ from the GBIC module?
A: They are two different form factors and can not replace each other. GBIC is an older version of the form that is bigger. Instead, SFP utilizes a compact size, providing around double port density. In addition, it supports enhanced DDM function for easy operating status tracking.
Q: How do you reprogram the CISCO switches?
A: The following procedure is offered on a trial basis and is not guaranteed to work successfully on all CISCO switches and firmware revisions. It is recommended that you update the firmware on the switch first to make sure the latest revision is installed, increasing the likelihood of success with this procedure. The switch model tested are 2960, 2970G, 3560, 3560G, 3750.
a. Connect to the switch console port and log on in “enabled” mode to allow privileged commands
b. Once enabled, enter “config t” to allow configuration from the terminal
c. Specify which port you would like to configure by entering the command “Interface Gigabit ?/?” where ?/? is the unit and port number you are trying to
re-configure
d. After entering that information, enter “service unsupported-transceiver”
e. Enter “Shutdown”. The switch will respond with a message stating that the port is administratively down.
f. Enter “no shutdown”. You may get a warning(s) about using “Unsupported Transceivers”, but once the messages are done, the port will come online and function normally with the Starview international SFP
Q: How do I choose a SFP for my application?
A: Basic key considerations when selecting an SFP are as followings:
-
- Protocol/data rate used on the equipment
- Optical transmitting wavelength preference
- Optical transmission distance. Note: 60km and above, we recommend user to specify the optical budget required for the link instead.
- Type of fiber used: Singlemode /Multimode, Dual Fiber/Single Fiber
- Form Factor: GBIC, SFP*, SFP+,XFP, etc
DDM preference
For other unique application, please contact our sales staff.
* Please note that SFP is also commonly known as mini-gbic.
