Cisco GBIC 1000Base-ZX Networking Transceiver Adapter WS-G5487

CISCO GENUINE. BRAND NEW. FACTORY SEALED. RETAIL BOXED. LIMITED LIFETIME CISCO WARRANTY. FROM CHICAGO COMPUTER SUPPLY

Overview

When your network must carry Gigabit Ethernet over long distances, you need a transceiver designed specifically for long-haul fiber. The Cisco WS-G5487 is a 1000Base-ZX GBIC designed for single-mode fiber (SMF) links up to 70 km, with the potential to reach even farther in premium fiber environments.

This GBIC module supports Gigabit Ethernet signalling at 1250 MBaud with 8B/10B encoding, making it a dependable choice for backbone links, metro-style connections, and extended enterprise fibre runs. It is not good for multimode fibre deployments, so it is best suited to long-distance single-mode infrastructure.

If you want a genuine Cisco GBIC optic that delivers long-distance performance with stability, the WS-G5487 is a strong match.

FAQs

What is the Cisco WS-G5487 used for?

The Cisco WS-G5487 provides 1G Gigabit Ethernet connectivity over single-mode fiber using the 1000Base-ZX standard for long-distance links.

What is the maximum distance supported by the WS-G5487?

It supports up to 70 km on standard single-mode fiber. In some premium fiber environments, link spans up to 100 km may be possible.

Does the WS-G5487 work with multimode fiber?

No. The WS-G5487 is designed for single-mode fiber (SMF) and will not operate correctly with multimode fiber.

What type of network applications is it best for?

It is best suited for long-haul enterprise backbones, metro-style fiber links, and extended uplinks that require long-distance fiber transmission.

What data rate does the Cisco WS-G5487 support?

It supports 1 Gbps (Gigabit Ethernet) connectivity for long-range fiber deployments.

Does this optic require an attenuator at short distances?

In some short single-mode deployments, you may need attenuation to prevent receiver overload. It depends on your link length and optical budget.

Is the WS-G5487 an SFP module?

No. It is a GBIC transceiver, which uses a proprietary GBIC interface rather than the smaller SFP form factor.

Is this product new and covered under warranty?

Yes. It is a genuine Cisco, brand-new, factory-sealed, retail-boxed, and covered by a Cisco limited lifetime warranty from Chicago Computer Supply.
