RUIJIE - GE-SFP-LX20-SM1550-BIDI - 1G BiDi LX SFP Module, 1550 nm TX / 1310 nm RX, 20 km, Simplex LC, Single-Mode

GE-SFP-LX20-SM1550-BIDI — 1G BiDi LX SFP Module, 1550 nm TX / 1310 nm RX, 20 km, Simplex LC, Single-Mode

The Ruijie GE-SFP-LX20-SM1550-BIDI is a bidirectional SFP with a 1.25 Gbps data rate for 1000BASE-LX links. It has a simplex LC connector and a 20 km reach over single-mode fibre (SMF).

What the GE-SFP-LX20-SM1550-BIDI is for

Ruijie position this module for data centre and campus networks, where it interconnects switches, routers, servers and network interface controllers. Its rated reach is 20 km over single-mode fibre.

It is a BiDi module that transmits at 1550 nm and receives at 1310 nm, so a single fibre carries traffic in both directions. It therefore works only as one half of a matched pair, with the other end using a module that transmits at 1310 nm and receives at 1550 nm. It supports DDM/DOM diagnostics and draws 1.5 W or less.

Key features

• Bidirectional SFP on a simplex LC connector: 1550 nm transmit and 1310 nm receive
• 20 km (65,616.80 ft.) reach over single-mode fibre (SMF)
• 1.25 Gbps data rate in an SFP form factor for 1000BASE-LX links
• Data diagnosis-capable, with DDM/DOM support
• Power consumption of 1.5 W or less per module
• Interconnects switches, routers, servers and NICs in data centre and campus networks

Full specification

What you will need

You need an SFP port on each end (on network switches or similar equipment) that accepts a 1G SFP module, and single-mode fibre (SMF) terminated with a simplex LC connector. The far end needs the matching 1310 nm TX / 1550 nm RX module, such as the GE-SFP-LX20-SM1310-BIDI. This is a 1G module and will not give 10G speeds.

Buying from Zenith Security Co.

We are a supplier, not an installer. We will go through the GE-SFP-LX20-SM1550-BIDI with you before you buy — which module goes at each end of the link, the fibre type and distance, and whether your switch ports take 1G SFP modules — and depending on your requirements and your area we can recommend a qualified trade installer. We have been operating since 2012 and you can visit our trade counter in Wolverhampton.

What do I need at the other end of a GE-SFP-LX20-SM1550-BIDI link?

A BiDi module that transmits at 1310 nm and receives at 1550 nm, such as the GE-SFP-LX20-SM1310-BIDI. BiDi modules work in matched pairs over a single fibre.

What distance does the GE-SFP-LX20-SM1550-BIDI cover?

Ruijie rate it at 20 km over single-mode fibre (SMF), at a 1.25 Gbps data rate.

Does the GE-SFP-LX20-SM1550-BIDI report diagnostics?

Yes. Ruijie list it as data diagnosis-capable (DDM/DOM). Power consumption is 1.5 W or less.

Can I use the GE-SFP-LX20-SM1550-BIDI in a 10G port?

It is a 1G module, so it needs a port that supports 1G SFP modules and will not run at 10G. Tell us the switch model and we will check.

How quickly can I get it?

Delivery is within 1–3 working days to England, Scotland and Wales. We do not ship to Northern Ireland.

Can I collect or see one before buying?

Yes. Our trade counter is at Unit 3, Park View Centre, 243 Dudley Road, Wolverhampton WV2 3JU. Call first so we can confirm the item is there for you.
