COMELINK 800G VR4 OSFP Optical Transceiver SR 01 2*400 1*800G with Dual MPO-12 Interface Flat Finned Top Riding HS NVI D

Comelink’s OSFP 2x400G VR4 transceiver module is designed for use in 2x400 Gigabit Ethernet links over 30m OM3 or 50m OM4 fiber. The module has 8 independent electrical input/output channels operating up to 106.25Gbps per channel. This transceiver consists of two transmitter/receiver units, with each operating on 850nm wavelength. The transmitter path of the module incorporates a PAM4 re-timer ASIC with two 4-channel modulator drivers and 8 modulated lasers. On the receiver path, it consists of 8 photodiodes and two 4-channel TIAs, along with the PAM4 re-timer. The electrical interface of the module is compliant with the 400GAUI-4 interface as defined by IEEE 802.3ck, and compliant with OSFP MSA.
What Are the Uses of SFP and How do They Convert Signals?

A SFP is a signal conversion interface for fiber-optic communications, converting large numbers of electrical signals into optical signals and vice versa. We often use various interfaces for interconversion in our daily lives, such as the Type C to USB conversion interface. The same is true for optical modules. Their core purpose is to convert electrical and optical signals. They are called "optical" modules, or "optical" transceiver modules, primarily to highlight the difficulty of processing optical signals.
KEXINT LC Uniboot Duplex OM4 LSZH Magenta Fiber Optical Patch Cord

KEXINT’s range of LC Uniboot style patchcord with integrated push/pull tab are the ideal solution for high density patching environments. The unique push pull tab allows easy finger access and a secure holding fixture for any patching or handling process. The attractive, low profile uniboot connector design utilises round 2 mm duplex cord for neater and denser cable management. For multimode OM4 and OM3 OM5 applications, low loss connectors are used to offer the lowest possible channel loss.
