Skip to content The Gigabit SFP module (Small Form-Factor Pluggable Transceiver) is a compact, hot-swappable network interface device. It typically refers to an SFP-encapsulated module with a 1.25Gbps data rate, based on the IEEE 802.3z standard’s 1000BASE-X series. Primarily used in network devices such as switches, routers, and firewalls, it converts electrical signals into optical signals or directly connects copper cables to achieve high-speed data transmission.
1.25G SFP modules are commonly referred to as “Gigabit modules” or “GE modules“; 2.5G modules are a “sweet spot rate” that offers higher bandwidth than Gigabit while consuming less power (only one-third that of 10G modules), making them more cost-effective. Both 1.25G and 2.5G SFP modules are “evergreen” products in the SFP packaging category, widely used in enterprise networks, security surveillance, industrial communication, and other scenarios due to their mature, stable, and high-performance-to-cost characteristics. Although there are differences in speed, their packaging and selection logic are largely consistent.
Yingda provide SFP small form factor pluggable modules with best fiber SFP price. All gigabit SFP modules are produced with brand new materials and high-end chips, 100% pass testing and comprehensive compatibility testing. They are widely compatible with switches and servers from brands such as Dell, Aruba, Moxa, Mikrotik, Cisco, HPE, Huawei, ZTE, Ruijie, H3C, etc.
Based on the transmission rate, operating wavelength, fiber type, and interface type of the optical module, Yingda divide gigabit SFP module into dual fiber bidirectional transceiver and single fiber bidirectional transceiver, copper SFP transceiver and PON transceivers. And Yingda can provide various specifications of modules according to customer needs, with specific models roughly as follows:

Confirm the compatibility between the module and the switch/device brand. Some brands (such as Cisco and Huawei) have software restrictions on third-party modules.
Almost all modern SFP modules support DDM, which can read real-time parameters such as temperature, voltage, and optical power of the module through the device, facilitating fault diagnosis and performance monitoring.
SFP module optical ports are mostly LC connector, PON module or GPON modules will use SC connector, and copper to fiber modules use RJ45 connector instead. So please ensuring that the cable match each other.
If using BiDi single fiber transceiver, it is necessary to confirm that the wavelengths of the two end SFP modules are paired (TX/RX are opposite), otherwise the link cannot be established.
Sure, for example, our SFP-1.25G-LSX, SFP-1.25G-BX01-3155, and SFP-1.25G-BX02-3155 are all single mode fiber module that use multimode fiber.
