The Huawei eSFP-GE-ZX100-SM1550 is a high-performance, single-mode transceiver module designed for Gigabit Ethernet connections. With its 1550nm wavelength and a reach of up to 100km, it ensures exceptional data transfer speeds and reliability over long distances. If the SFP-10G-ER-1310 is connected to a 10Gbase-ER standard optical module (1550nm, 10GE, 40km), the maximum transmission distance is only 20km due to different specifications such as wavelength and receiving sensitivity. Single-fiber bidirectional (BIDI) optical modules must be used in pairs. Every eSFP-GE-ZX100-SM1550 is environmentally tested in its specific port/platform prior to shipping to ensure that they are in perfect. 02315206 - Genuine Huawei eSFP-GE-ZX100-SM1550 Optical Transeiver, eSFP, GE, Single-mode Module (1550nm, 100km, LC) Basic Information Transmitter Optical Characteristics Receiver Optical Characteristics This Huawei eSFP-GE-ZX100-SM1550 Optical Transeiver, eSFP, GE, Single-mode Module (1550nm.
