Description
A plain-named 1000BASE-SX SFP that Juniper lists for routers, firewalls and some switches, under its own part code 740-031851. Typical roles are Gigabit handoffs between a security gateway or edge router and an adjacent switch inside the same room or building. Its published reach is shorter than the EX/QFX variants, at 200 m and 500 m depending on fibre type, with a transmit window of 770 to 860 nm. The compatibility entry does not state digital monitoring support. Cabling for SFP-1GE-SX: use a duplex multimode patch cable with LC connectors, OM3 or OM4 preferred for the longest reach. The headline reach is 500 m on 50/125 µm MMF · 200 m on 62.5/125 µm MMF, so measure the installed link loss before ordering. The host needs a free SFP cage that runs at 1G; Juniper's tool names MX204 among the platforms where this code is supported, and the model page also gives the minimum software release for each platform. Clean the connectors before insertion and keep dust caps on unused ports.
Typical uses
- Server and storage links to a top-of-rack switch
- Switch-to-switch links inside one data hall or comms room
- Building risers that already have OM3/OM4 multimode fibre
Before you order
- Confirm your switch or router model and software release support the SFP-1GE-SX
- Use OM3 or OM4 multimode patch cords; reach drops sharply on OM1/OM2
- Prices exclude import duties and taxes in your country (DAP)
