Description
A gigabit short-wavelength optical module for SFP ports, working at 850 nm over duplex multimode fibre. It is the usual choice for linking access and aggregation switches inside a building or across a campus floor plan, where a run stays within a few hundred metres. On 50/125 micron fibre rated at 500 MHz·km the stated span is 550 m, dropping to 500 m on 400 MHz·km fibre and 275 m on older 62.5/125 micron cable. Optical output sits between -9.5 and 0 dBm, and receive sensitivity is specified from -17 to -3 dBm. Digital optical monitoring is built in, so link power can be read from the switch. The module draws about 1 W and is rated for 0 to 70 degrees C. Both ends of a link need matching short-wavelength optics, and the connector is a standard LC duplex pair.
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 J4858D
- Use OM3 or OM4 multimode patch cords; reach drops sharply on OM1/OM2
- Prices exclude import duties and taxes in your country (DAP)
