Huawei eSFP-GE-SX-MM850 1000BASE-SX 850nm Multimode GE eSFP Optical Module (550 m on OM2, 02315204)

Product Overview

The eSFP-GE-SX-MM850 (Huawei part number 02315204) is an enhanced small form-factor pluggable (eSFP) optical module for 1.25 Gbit/s 1000BASE-SX Gigabit Ethernet links. It operates at an 850 nm center wavelength over multimode fiber with an LC/PC duplex connector and is documented by Huawei for up to 550 m on OM2 fiber and 1 km on OM3/OM4 fiber.

As an eSFP-class module it supports digital diagnostics monitoring (DDM), exposing supply voltage, module temperature, laser bias current, and transmit/receive optical power to the host in real time. Huawei documents an extended operating case temperature of -20°C to +85°C, giving extra margin for poorly conditioned equipment rooms and edge cabinets beyond the standard 0-70°C commercial range.

Typical applications include GE uplinks and access links between Huawei campus switches, routers and servers over existing multimode fiber backbones, such as building risers and short campus runs where 1000BASE-SX connectivity over OM2/OM3/OM4 cabling is already in place.
