High Reliability SFP28 SR4 25G Optical Transceiver With High Performance 850nm 100m LC MMF

UnitekFiber supplies multimode 25G SFP28 optical transceiver with a center wavelength of 850nm, and conforms to multiple standards and specifications such as IEEE 802.3, SFF-8472, SFF-8402, SFF-8432, and SFF-8431. Unlike other optical transceivers, the internal transmitter of this optic transceiver is a vertical cavity surface emitting laser (VCSEL), so it is suitable to be used with OM3/OM4 multimode fiber with a fiber diameter of 50/125µm.

High Reliability SFP28 SR4 25G Optical Transceiver With High Performance 850nm 100m LC MMF


The Cisco-compatible SFP28 transceiver provides up to 10 km of 25GBase-BX throughput over single-mode fiber (SMF) using 1330nm-TX/1270nm-RX wavelengths via LC simplex connectors. This bi-directional unit must be used with another transceiver or network equipment of complementary wavelengths. Optical transceiver provides 25GBASE Ethernet connectivity options for 25G Ethernet, telecom and data centers. It is fully compliant with SFF-8472, SFF-8402, SFF-8432, SFF-8431, MSA and eCPRI standards.

What are the types of 25G optical modules?

25G optical modules are roughly divided into three types, 25G dual-fiber modules, 25G WDM modules, and 25G BIDI modules.

Is there any damage to the module if it is used for transmission over a short distance of 10m for an 25G optical module of 10km? Do I need to use attenuator?

We need to ensure that the receiving power of the module is not more than the receiver overload power to avoid the module being broken. So to get the 25G LR to work at 10m, you need to add about 3dB attenuation.

Are any of these modules compatible with Huawei Equipment?

Yes, Unitekfiber's optical modules are compatible with Fiberhome, Huawei, ZTE, Cisco, Ericsson, Nokia and other brands.

How much power does this 25G SFP transceiver draw?

The power consumption of this module <1w.

Can SFP28 ports be interconnected with QSFP28 ports?

100G SR4 multi-mode optical modules can be used for interconnection. Under the premise of equipment support, 100G QSFP28 ports can be configured as 4*25G mode, and then MPO-LC fiber jumpers are used to connect 100G SR4 optical modules and 25G SFP28 optical modules.

What is the maximum transmission distance of the 25G SFP28 optical module?

At present, 25G SFP28 optical modules can transmit up to 40 kilometers. There are 25G SFP28 ER, 25G SFP28 bidi, 25G SFP28 CWDM, and 25G SFP28 DWDM.
